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. 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. Messaging is gaining momentum in electronic commerce and have many advantages. One person can start the form, mail it to the next person, fill it, mail it to the next, and so on. E-commerce is the buying and selling the goods and service through digital communication. The relationships among them are probably best described graphically in figure. When it comes to managing the data, it is mandatory to get precise and accurate details over the data. The next 21 bits represent the network identifier. 2. Explain the various Security Protocols associated with E-commerce? Frame work of E-commerce Infrastructure Common business services infrastructureMessaging and information distribution multimedia content and network publishing N/w infrastructure Interfacing infrastructure Policy making support areas 1.People-buyers,sellers,intermediaries, services.IS people 2.Public policy-taxes ,legal , privacy issues,regulations … At present, credit card numbers, financial records, and other important information are not encrypted and can be intercepted by any internet hacker. Public data: have no security restrictions and can be read by anyone. TCP operates at the transport layer of the OSI model, while IP operates at the network layer. This protocol fully encrypts all the information in both the HTTP request and the HTTP response, including the URL the client is requesting , any submitted form contents (including things like credit card numbers), any HTTP access authorization information (user names and passwords) and all the data returned from the server to the client. this is called reliable protocol since delivery of all guaranteed, if packets get lost along the way, they are automatically resent. The remaining 24 bits identify the specific host. 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. 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. Aimers (Laravel, Symphony, Typo3, Flow) Spyker (Symfony only) Sylius (Symfony only) The key framework feature which are vital for eCommerce businesses are: 1) Quality Search Functionality Information brokerages dispatch agents capable of information resource gathering, negotiating deals and performing transactions. It is a noncommercial or more research oriented security and is similar to S-HTTP. Information Brokerage and Management: The information brokerage and management layer provides service integration through the notion of information brokerages, the development of which is necessitated by the increasing information resource fragmentation. 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. Another protocol, Privacy Enhanced Mail (PEM), was put forth by IETF and the IRTF in late 1980s. A one-one-zero in the first three bits represents this class. When an employee sends an electronic form, the information travels with the form. 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. FTP is a common tool used for uploading web documents to a server. 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. They offer an environment for building e-commerce applications quickly. If you have your own Study Notes which you think can benefit others, please upload on LearnPick. The second mode, connectionless splits the message into packets or datagrams and sends them intermittently to the destination. The basic DES encryption steps are : 1. Architectural Framework of E Commerce. Through e-governance, government services will be made available to citizens in a convenient, efficient and transparent manner. 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. RC2 and RC5 are block cipher algorithms and RC4 is a stream cipher. 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. E Commerce and Business Technology. Examples of structured document messaging include EDI. 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 designing part also needs to be done very carefully. It must have ability to use the third party plug-ins which is meant to provide adaptability, customization and innovation. 1. 5. IT & Computer Subjects, Computer Science, IT, BBA ... Factors Influencing The Consumer Perceptions To Buy Online. To maintain the relationships that are critical to delivering superior customer value, management must pay close attention to service, both before and after sales. A windows version of FTP, WinFTP, makes file transfer procedures trivial. Placement on EP Framework. 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? By harnessing the power of the internet, electronic commerce has changed the way in which organisations conduct business. 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. UNIT-II Explain architectural framework for electronic commerce? It can be broadly defined as the process of buying or selling of goods or services using an electronic medium such as the Internet. You can … The framework of e commerce is designed in such a way that It offers more flexibility when surfing from one page to another. The next 14 bits represents the network identifier. Secret data: existence is a secret. 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. FTP: A popular method for uploading and downloading files is the file transfer protocol (FTP). 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. 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. Security socket layer (SSL): uses RSA security to wrap security information around TCP/IP based protocols. allow replacing all parts of the framework code; forbid changes in the framework code itself; contain bootstrap code to start the application; be extensible by user-written code; E-Commerce frameworks should. This presentation is based on a memorandum written by James Dempsey, the Global Internet Policy Initiative’s chief lawyer. Some collaborative workgroup software, such as Netscape's Collabra, is built to be compatible with NNTP-compliant servers so that interactive discussion group session can be held. The following figure shows the components involved in E-commerce infrastructure. At destination, the datagrams are collected and reassembled and any lost packets are identified. E-commerce frameworks must be based on a strong architectural model. Post was not sent - check your email addresses! An encryption process that uses a block cipher technique takes a fixed block text 64bits. It defines actually how e-commerce implemented, how online trading or business can be done. 2. The layers are Application Layer: This layer is a service used to communicate with the actual application in use. helpful 320 32. This gives users and applications transparent access to data, computation, and other resources across collections of multi-vendor, heterogeneous systems. 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. It addresses the issue of adding value to the information that is retrieved. E-Commerce frameworks are flexible enough to adapt them to your specific requirements. One advantage of S-HTTP is that is supports end-to-end secure transactions. Information brokers, for example are rapidly becoming necessary in dealing with the voluminous amounts of information on the networks. E-Commerce frameworks should. The encoded message- the cipher text is unintelligible to anyone intercepting the message. The benefit of SSL over S-HTTP is that SSL is not restricted to HTTP, but can be used for security for FTP and TELNET, among other Internet services. 3. 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. Class D and Class E: These classes are reserved for special and experimental purposes. Network News Transfer Protocol (NNTP) is an IETF standard that is explained in its basic form in RFC 977. 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.
