NNTP: One of the great benefits of the Internet is the ability to easily share information. Public data: have no security restrictions and can be read by anyone. PGP and PEM are programs that allow a sender and a receiver to communicate in a way that does not allow third parties to read them and that certify that senders are really who they claim to be. IP Addresses: When a message is sent, IP address for both the sending and receiving nodes must be known. Several methods can provide security in the web framework. Only 126 class A addresses exist. NNTP is designed as on open Internet Protocol to facilitate the distribution, inquiry retrieval and posting of news articles. Brokerages may provide tools to accomplish more sophisticated, time- delayed updates or future-compensating transactions. The challenge with symmetric encryption schemes is disseminating the shared key to both the sender and the receiver while keeping this key a secret from everyone epically in those instances when the sender and receiver are geographically separated Data encryption standard: The primary symmetric encryption algorithm in use is the data encryption standard (DES), developed in 1977 by IBM for the U.S government. 4. scramble a 64-bit text block one time divide the 64-bit block into two 32-bit block take each of the 32-bit block and scramble them 16 times using the secret DES key, and Apply the inverse of the initial scramble. Messaging is central to work-group computing that is changing the way the business operate. It is a concept of goods and services which are been provided to the medium of the internet as the main aspect of buying, selling, and exchange. Examples of structured document messaging include EDI. Written for the GIPI Country Coordinators last May, it is titled “The Regulatory Framework for E-Commerce – International Legislative Practice.”. 1. With the growth of networks, client-server technology, and all other forms of communicating between/among unlike platforms, the problems of getting all the pieces to work together grew from formidable to horrendous. Would you like to get the full Thesis from Shodh ganga along with citation details? Copyright data: have content that is copyrighted but not secret. The agents are intelligent because they have contingency plans of action. Messaging is well suited for both client-server and peer-to-peer computing models, distributed systems, the messages are treated as "objects" that pass between systems. Directory services databases make data from any server appear as a local file. This process requires that both the sender and the receiver maintain three separate secret keys, if any of the keys are lost, the cipher text is irretrievable. A related value A, is derived form a. It must have ability to use the third party plug-ins which is meant to provide adaptability, customization and innovation. It addresses the issue of adding value to the information that is retrieved. A framework is intended to define and create tools that integrate the information found in today's closed systems and allows the development of e-commerce applications. The three main target groups that can be distinguished in The fact is that everyone is looking forward to have easy browsing on mobile than to go for getting an efficacious platform, which will surely help to grow user and customer’s attraction. All three algorithms have variable key lengths. The next 21 bits represent the network identifier. These features can be used while developing a website and though some may not be the part of the standard package. Another method is the Internet Message Protocol (IMAP). The relationships among them are probably best described graphically in figure. To provide security, the Netscape Navigator supports a new URL access method, https, for connecting to HTTP servers using SSL. 2016/2017. It is much stronger than DES since it employs an 80-bit key, and instead of scrambling the data 16 times, it scrambles it 32 times. What do they charge? An interactive catalog is an extension of paper based catalog and incorporates additional features such as sophisticated graphics and video to make the advertising more attractive. E-Commerce framework architecture. How do you use it? The framework for increasing sales and efficiency in e-commerce includes the following elements: Business – a key element in the structure. A classic example of a directory is the telephone white pages, which allows us to locate people and telephone numbers. At destination, the datagrams are collected and reassembled and any lost packets are identified. Transparency is accomplished using middleware that facilitates a distributed computing environment. This protocol eliminates the need to maintain multiple preferences and address book files. Usually, they make heavy use of interfaces and design patterns like. Advanced encryption standard: The advanced encryption standard (AES) will prove to be a stronger encryption mechanism. The E-Commerce Package includes the Framework of Standards on cross-border e-commerce as well as documents supporting its implementation. Similar to IMAP, but recently developed by the IETF, is an e- mail protocol, application Configuration Access Protocol (ACAP), which allows the user to store his/her mail preferences and address books directly on the server. TCP/IP: The most widely used protocol on the internet is the Transmission control Protocol/lnternet Protocol(TCP/lP),a set of protocols developed in 1970s. The protocol provides symmetric capabilities to both client and server while preserving the transaction model and implementation characteristics of the current HTTP. helpful 320 32. Proposals for Strategic Improvements. 6. Placement on EP Framework. Information brokerage does more than just searching. An e-commerce framework must. This is a stateless protocol. This handshake results in the client and server agreeing on the level of security they will use and fulfills any authentication requirements for the connection. When a user clicks on a link to a web page, the connection is opened, data is transferred and the connection is broken.Request- response protocol that allows different platforms and applications to exchange documents. Basically this function is kind of filtering which processes keywords and helps you to get precise effect over search and into your sales too. Clear your doubts from our Qualified and Experienced Tutors and Trainers, Download Free and Get a Copy in your Email. It is a noncommercial or more research oriented security and is similar to S-HTTP. Middleware Services: Middleware is relatively new concept that emerged only recently. Note that while this method provide greater security against attacks, it also requires more computation time To encode the message three times and then to decrypt each message layer. mail for purchasing goods and services, buying information and consulting services, submitting requests for proposals, and receiving proposals. Hardware: By harnessing the power of the internet, electronic commerce has changed the way in which organisations conduct business. Network Layer: The layer performs data routing and delivery across multiple nodes. One of the objectives of e‐Business is to provide seamless connectivity and integration between business processes and applications external to an enterprise and the enterprise’s back office applications sucha as billing, orger processing, accounting, inventory and receivables, and services focused to total supply chain management and partnership including product development, fulfillment, and distribution. Business-to-Business Transaction: We call this category market-link transaction. 2. Client's conversation with the server is private (privacy using encryption). Encryption techniques: Confidentially of electronic messages is a necessity of electronic commerce application the primary method of achieving confidentiality is encryption. “ ...Perhaps the single most important thing … A framework is intended to define and create tools that integrate the information found in today's closed systems and allows the development of e-commerce applications. MESSAGING PROTOCOLS: The protocols that have evolved to enable the electronic transmission of messages over the internet. This note covers the following topics: E-Commerce, E-Business, Social Networking, Mobile Commerce, Internet and E-Commerce Statistics, E-Commerce Models, E-Commerce Business Planning, E-Commerce Infrastructure, Design and Build Mobile Sites and Apps, E Commerce Security and Payment Systems, Netflix, E-Commerce Marketing Communications and E-Commerce … TOPIC 1: E-COMMERCE FRAMEWORK, BUSINESS MODELS AND ENVIRONMENT 1.1 Define electronic commerce (EC) and describe its various categories. These tools include software agents, distributed query generator, the distribution transaction generator and the declarative resource constraint base- which describes a business rules and environment information. BASIC MAIL PROTOCOLS: Four mail protocols are discussed in this section. If you have your own Study Notes which you think can benefit others, please upload on LearnPick. Messaging is the software that sits between the network infrastructure and the clients or electronic commerce applications, masking the peculiarities of the environment. 3. The main disadvantages of messaging are the new types of applications it enables-which appear to be more complex, especially to traditional programmers. The encoded message- the cipher text is unintelligible to anyone intercepting the message. E Commerce and Business Technology. It performs tasks as converting messages into the necessary format for use by the application. Three major components of market-driven transactions are customer orientation through product and service customization, cross-functional co-ordination through enterprise integration, and advertising, marketing and customer service. Website speed plays a vital role in the whole architectural framework of e commerce sites. Transparency is essential for dealing with higher level issues than physical media and interconnection that the underlying network infrastructure is in charge of. A company becomes market driven by dispersing throughout the firm information about its customers and competitors by spreading strategic and tactical decision making so that all units can participate and by continuously monitoring their customer commitment by making improved customer satisfaction an ongoing objective. Explain the various Security Protocols associated with E-commerce? Electronic commerce: a conceptual framework Application services Brokerage and data management Interface Layer Secure messaging Middleware service Network Infrastructure Consumer-to-Business Transaction: Customer-to-business Business-to-Business Intra-organizational Order processing mail order houses Payment schemes electronic cash Clearing house or virtual mall Interactive catalogs Directory support functions Software agents Secure hypertext transfer protocol Encrypted e-mail, EDI Remote programming (RFC) Structured documents (SGML,HTML) Compound documents (OLE, Open Doc) Wireless cellular, radio, PCS Wire line-POTS, coaxial, fiber optic We call this category market place transaction. The next 14 bits represents the network identifier. This protocol allows users to search for specific topics of interest. Course. RC5 is also a block cipher that has variable block size ranging from 32 to 128 bits, a variable key sizing ranging from 0 to 2,048 bits, and a variable number of scrambling round range from 0 to 255 Asymmetric cryptography: The sharing and dissemination of secret key present's implementation problem in keeping the shared Secret key confidential. The aim of the architectural framework itself is not to build new database systems, data repository, computer languages, software agent based transaction monitors, or communication protocols. SSL: SSL is layered beneath application protocols such as HTTP, SMTP, TELNET, FTP Gopher and NNTP and above the internet connection protocol TCP/IP. The Legal Framework for E-commerce in the Internal Market 15-05-2020 This study presents an overview of the current state of play in the area of e-commerce. They examine themselves and their environment and if necessary change from their original course of action to an alternative plan. When conditions changed along with hardware and the software the organizations couldn't cope. Examples are electronic mail, enhanced fax, and electronic data interchange. SECURITY ENHANCED MAIL PROTOCOLS: Some commercial e-mail services use a protocol called requires that e-mail be sent along paths with only known, trusted e-mail carriers, such as AT&T and MCI. Academic year. When an employee sends an electronic form, the information travels with the form. Comments. To ensure a secure conversation between a web client and server, S-HTTP works by negotiating the type of encryption scheme used between client and server. FTP: A popular method for uploading and downloading files is the file transfer protocol (FTP). This class can only represent 256 host computers on a network. E-commerce is an important element in the manufacturing industry such as MODENAS for them to participate in the worldwide markets globalization. Where each communicating entity has a unique key pair (a public key and a private key) Confidentiality service may depend on a number of variables associated with the encryption function. These include the following: S-HTTP: is a revision of HTTP that will enable the incorporation of various cryptographic message formats, such as DSA and RSA standards, into both the web client and the server, most of the security implementation will take place at the protocol. 2. It also performs error detection and control functions. Define the general program flow; Consist of reusable components; Be organized in functional domains; Examples of e-commerce frameworks are. Many commercial applications require that the client and server be able to authenticate each other and exchange data confidentially. The following figure shows the components involved in E-commerce infrastructure. Post was not sent - check your email addresses! After giving the remote host, userlD, and password information to the software, it will log onto the desired system and show the local directory in one window and the remote directory in another window. It includes 15 short, concise standards, which on the one hand are intended to simplify the harmonization of processes and on the other hand still leave enough freedom for pragmatic and innovative solutions in regard to national differences and concerns. Directories on the other hand, operate behind the scenes and attempt to organize the enormous amount of information and transactions generated to facilitate electronic commerce. The first mode, connection-oriented, transmits the entire message in a data stream, connection is established, the data is transferred, error checks are performed and receipt of data is confirmed, and the connection is closed. To transfer files, all one has to do is point and click. As result, they are suitable for building virtually all kinds of online shops and e-commerce related (web) applications.

(PDF) Electronic Commerce Business Models: A Conceptual Framework | Ganesh N Prabhu - Academia.edu Abstract The recent boom in the new economy of internet based commerce has created a large number of firms with a variety of business models that aim to leverage the power of the internet to further their business goals. Security and confidentiality are essential, before businesses can conduct financial transactions over the internet, and a lack widespread security measures remains at this time. This means that multiple encryption/decryption need not be done at very intermediate point. They provide an overall structure for e-commerce related applications. Presentation Layer: This layer negotiates the syntax of the data transferred Session Layer: This layer is responsible for establishing and maintaining communications channels. Information brokers, for example are rapidly becoming necessary in dealing with the voluminous amounts of information on the networks. Thereafter, SSL's only role is to encrypt and decrypt the message stream. Another advantage of messaging is that it is not associated with any particular communication protocol. Messaging is gaining momentum in electronic commerce and have many advantages. A structured document messaging consists of the automated interchange of standardized and approved messages between computer applications, via telecommunications lines. Configuration, Product management, Marketing & Design, Technology & Storefront, Internationalization, PayPal Extensibility, manufacturer support, extendable via plugins, product Streams. The layers are Application Layer: This layer is a service used to communicate with the actual application in use. Conceptual Framework Internet economy is a broader term which includes both e-commerce and e-business. First, basic e-mail store and forward and remote server protocols were introduced and security related protocols are introduced. HTTP: The protocol that underlies the WWW is called the HyperTextTransfer/transport protocol(HTTP). E-commerce is the buying and selling the goods and service through digital communication. 4.Explain the security issues involving E-commerce transactions. Triple encryption: The strength of DES encryption is generally thought to be increased by using triple encryption. A windows version of FTP, WinFTP, makes file transfer procedures trivial. The tools were inadequate, the backlog was enormous, and the pressure was overwhelming. Is known as message enabled work- flow solutions. The client side with PEM uses the finger program to retrieve the server's public key, PEM or PGP encryption will need to communicate before hand and find a secure way to exchange their public keys 5.Explain the various Encryption techniques. 1. E-commerce-notes-pdf-lecture-notes-university-level. For each approved study note you will get 25 Credit Points and 25 Activity Score which will increase your profile visibility. Integrate messaging is a group of computer services that through the use of a network send, receive, and combine messages, faxes and large data files. Encryption is defined as the transformation of data, via a cryptographic mathematical process, into a form that is unreadable by anyone who does not possess the appropriate secret key. Conceptual Framework of E- commerce Framework tells about the detail of how ecommerce can take place. However, determining a right framework for e-commerce solutions and evaluating its potential for success is a major challenge. Sorry, your blog cannot share posts by email. Security, privacy and confidentiality through data encryption and authentication techniques are important issues that need to be resolved for ensuring the legality of the message based transactions. As of the writing of the text, fifteen cryptographic developers have submitted candidate AES algorithms. Unstructured messages consist of fax, e-mail and form-based systems like lotus-notes. The best way to conduct triple encryption is by using three different secret keys in the process as illustrated in figure. In business electronic messaging is a critical issue. It discusses the existing legislative framework of the Digital Single Market as well as the technology-driven changes of market and economy that have taken place over the last twenty years. We use the notion of information brokerage to represent an intermediary who provides service integration between customers and information providers, given some constraint such as a low price, fast service or profit maximization for a client. IT & Computer Subjects, Computer Science, IT, BBA ... Factors Influencing The Consumer Perceptions To Buy Online. S-HTTP secured clients can talk to S-HTTP obvious servers and vice-versa, although such transactions obviously would not use S-HTTP security features. The public key method allows a sender and a receiver to generate a shared, secret key over an insecure telecommunication line. The primary difference between the two is that unlike interactive catalogs, which deal with people, directory support services interact directly with software applications. It is the system which makes your website unique in searches across the global markets. Academia.edu is a platform for academics to share research papers. University of Rajasthan. Explain the messaging protocols over the internet? For DES. What is an eCommerce framework? It acts as a central clearing house for storing messages until they are retrieved and downloaded. Class C: This class is used for small networks. These elements are classified as different layers as per the framework given by Center for Research and Electronic Commerce (CREC) at the University of Texas in the… OSI: A general reference model for the standardization of data communication procedures that support interoperability is the ISO Open Systems Interconnections (OSI) model released in 1984. Another protocol, Privacy Enhanced Mail (PEM), was put forth by IETF and the IRTF in late 1980s. Electronic commerce (or e-commerce) has evolved over the years to become a major channel through which businesses can exchange goods and services, coordinate production and market to customers. such data might include algorithms. In a marketplace transaction, customers learn about products differently through electronic publishing, buy them different using electronic cash and secure payment systems, and have them delivered differently. When it comes to managing the data, it is mandatory to get precise and accurate details over the data. It allows the user to access and read mail directly from the server without having to download it. You can … The IP addresses are 32 bits in length, decomposition of IP addresses varies according the assigned class. Secret data: existence is a secret. The other 16 bits represent the hosts on each network. Please sign in or register to post comments. Nupur Khandelwal. Interactive catalogs are the customized interface to consumer applications such as home shopping. Information brokerages dispatch agents capable of information resource gathering, negotiating deals and performing transactions. S-HTTP does not require client-side public key certificates. By business we mean such features/components as quality of the product or service, pricing, time of delivery, customer service and differentiators from the competition. Skipjack: The national security agency (NSA) designed a stronger encryption algorithm, called skipjack. The technology and infrastructure used to develop the E-commerce application is the key to its success. The message encrypted with the first key, decrypted with the second and encrypted again with the first key. As online databases migrate to consumer information utilities, consumers and information professionals will have to keep up with the knowledge and ownership of all these systems, who's got what? – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 4f3200-M2JiM Designing the flowchart is a key point in any ecommerce website development. The primary security features of PEM are: • Origin authentication and non-repudiation • Message integrity and • Message confidentiality PEM was incompatible with the rapidly emerging multi-media Internet protocol, Multipurpose Internet Mail Extension (MIME) and this in compatibility seriously impeded PEM's commercial success. During its implementation it became a public key method. Finalized E-commerce Preparedness Framework based off of position papers. Electronic Commerce Application Secure Hypertext Transfer Protocol(SHTTP) TCP based application protocol Secure Socket Layer (SSL) Internet Protocol ('P) Fig: Web Security Layers The server implements server-side support for HTTP over SSL, including support for acquiring a server certificate and communicating securely with SSL-enabled browsers. The framework of e commerce is designed in such a way that It offers more flexibility when surfing from one page to another. The store and forward protocol is Post Office Protocol (POP). This is typically implemented with an encrypt-decrypt-encrypt, where two keys are used, not three. The designing part also needs to be done very carefully. The last three layers are called the upper layers because they deal more with message handling of the data packets transferred. RC2 and RC5 are block cipher algorithms and RC4 is a stream cipher. Electronic commerce draws on technologies such as mobile commerce, electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems. Intra-organizational Transactions: We call this category market-driven transaction. It negotiates packet recovery and provides synchronization check points for data packets transmitted. Document that summarizes the teams’ overall findings and provides supporting documentation for each area on the E-commerce Preparedness framework. The full memo can be found at the GIPI website, http://www.internetpolicy.net/. Data Link Layer: The layer performs the transmission of data, control from one node to another node. Here, businesses, governments, and other organization depend on computer-to-computer communication as a fast, an economical and a dependable way to conduct business transactions. A one-zero in the first two bits represents this class. 5. The OSI model consists of seven layers. Class D and Class E: These classes are reserved for special and experimental purposes. Several cryptographic message format standards can be incorporated into S-HTTP clients and servers. The mail can be managed directly on the server by having a remote file server connection. SHEN: is a security scheme for the web sponsored by the W3 consortium. And transform the 64bit block to text into a 64bit block of cipher text.
