This paper describes the application of EDI in electronic commerce, analysis of the open-edi solutions to security problems discussed EDI applications and security of legal protection. Introduction EDI will be business to business commercial transactions between the documents and information data files, use of computer networks and communication networks to standardized file format, the use of electronic means in the computer applications and computer application systems and directly to the information business exchange and processing. EDI is used between the computer transmission of business information, including daily consultation, planning, procurement, Arrival Notice, Request, payment, financial reports, etc., especially when the telecommunications sector after the introduction of value-added network services, such private information exchange system has been great development. EDI's research has focused on the automatic message processing and standardization, with the EDI system based on Internet open appearance and rapid development, EDI has become a security must be closely watched and in-depth study of important issues. EDI Overview EDI technology is the business according to a recognized standard file from one computer to another computer, the electronic transmission of up method, because EDI greatly reduces the paper notes, so people also called the image of EDI as a "paperless trading" or " paperless transactions. " EDI originated in Europe and the United States 60 years, first for the U.S. transportation industry, the real development is lagging behind in the 80's, and its application to create a "paperless trading" in the new era, which was described as a "commercial revolution structural "After repeated applications through continuous improvement and gradually extended to all over the world. Currently, the developed countries and some developing countries in Europe and America, EDI has become the most basic means of foreign trade and contact, are widely used in trading companies, customs, commodity inspection, banking, transportation and insurance sectors or industries, and has achieved huge economic benefits to its users at an annual growth rate of 40%, as a new type of trade, EDI has begun to become a leading international trade. EDI has the following characteristics: (1) EDI data is sent by general business information, such as invoices, orders, etc., not the general notice; (2) EDI is the use of the object with a fixed All rights reserved.

EDI Application in Electronic Commerce E-commerce (Electronic Commerce) is an open network environment of the Internet, browser-based, server applications ways to achieve the consumer's online shopping, online transactions between merchants and online electronic payment of a new business model. EDI lies in the realization of computer hardware and software, communication networks and data interface between the three aspects of standardization, the development of e-commerce play a key and decisive role. 2.1 EDI's role in e-commerce links In normal business transactions, buyer seller orders. Sellers receive orders to carry out its internal processing of paper writing paper, ready for delivery, paper bills, including invoices and so on. The buyer after the receipt of goods and invoices, write checks, sent to the seller, the seller holds the check to the bank to cash. To open a bank notes, a summary of this amount is recognized. EDI system, a production enterprise is to bring the buyers and sellers in the trade process all the paper-based documents from the EDI communication network to send, all done automatically by the computer (or most) process. Specifically: 1) to send the goods owners (such as the manufacturer) after receiving the order specified cargo program and a list of the delivery of goods and delivery schedule and other information sent via EDI to the logistics and transport the goods owners and the owners plan to receive the goods specified ; 2) then send the owners of goods according to customer requirements and delivery of goods ordered plans to issue delivery instructions, picking sorting, print out the logistics of goods bar code labels and stickers on the box of goods, while the variety of delivery of goods, quantity, packaging and other information sent via EDI to the logistics transport and receive goods owners, vehicle deployment orders issued pursuant to referrals; 3) logistics and transport owners to take to the owners of cargo shipped the goods, the use of the goods vehicle scanning reading devices to read bar code logistics label and the transport of goods with the previously received data verification to confirm delivery of goods. 4) Finally, the owners receiving the goods arrived, the goods by scanning the reading device reads the bar code logistics label, and with the previously received data check, the carriage of goods, out of receiving the invoice, goods storage: same time, through EDI to the logistics and transport owners and the owners sent the goods to send confirmation of receipt. 2.2 EDI in the supply chain Management In supply chain management applications, EDI is the supply chain is an important tool for information integration. Is also a partner in the cooperation between enterprises of effective technical means of information interaction, particularly in the global economy, global trade cooperation, it is a link in the supply chain, each node in the enterprise business applications for medium. 2.3 EDI's benefit evaluation 1)The parties to the transaction information transmitted via computer communication network, and instantly, which amounts, can greatly shorten the supply chain business operations between the time of each node; 2) As a computer information processing is done automatically, without human intervention, except to save time outside the business can significantly reduce the error rate process, thereby reducing the cost of data processing errors. 3) save inventory costs of all nodes in the

3 438 Computer and Information Technology enterprise. Greatly reduced after the use of EDI supply and demand sides of the business processing time, which need to be reducing inventory, reducing inventory costs. 4) Save the personnel costs of each node enterprise. After the use of EDI is no longer need to manually fill in a form, single, binding, packaging, mailing and a series of processes, can save human nature; 5) to achieve paperless trading enterprises of each node, a substantial savings in paper, printing, storage and mailing costs, which reduces the cost of trade documents; 6) The internationalization of the firm, as the business use of EDI, business is no longer subject to geographical constraints, but to the world. 7) The application in the supply chain EDI, can eliminate a lot of uncertainty factors. The most important supply chain uncertainty is the ultimate consumer demand, consumer demand must be made on the final forecast as accurate as possible, the needs of the supply chain but also on information from this demand forecast. EDI security mechanism EDI standard digital technology used to replace manual document packet transmission, to achieve the automatic order generation, transmission and processing, greatly improving the efficiency and effectiveness of business activities, transactions can not be fully comparable to the great advantage. But it is in the EDI message as e-commerce and traditional commerce with the same legal effect as manual documents, and more difficult to verify than manual document, and thus how to ensure a true and complete EDI message and the safe, reliable, has become a development is based on Internet EDI system, the key to open. To achieve the Internet, secure transmission of EDI messages should be resolved authentication, confidentiality, data integrity and refused to deny the problems, of which identity is made unilaterally, and unilaterally to close the true identity of the other mutual authentication; is confidential message that there is no interpretation of theft by unauthorized persons; data integrity refers to the packet data is not lost, altered or damaged; unilateral rejection is issued can not deny the message issued by EDI, and the agencies can not deny that received unilateral of EDI messages. More familiar for both sides, more business, the case of a large amount of data communications, can be a virtual private network VPN, dedicated agreed by the parties encryption and authentication algorithms, re-set on the IP datagram packet and ESP header and the latter part of All the inner IP data encryption, which in both the internal network to establish an encrypted tunnel between security gateways, both to ensure data security, and simplify the mutual authentication complexity and unfamiliar for both sides, business exchanges less data traffic is relatively small, the true identity of identity not only includes the identification, but also on the credibility of the confirmation, CA certificate should be the core encryption and authentication system to ensure data transmission security. Conclusion In short, EDI standardization of data packets through the realization of the automatic generation of business documents, transport processing, you can use VPN or a CA certificate-based encryption and authentication system to ensure their safety, and only really, really involved to solve the legal EDI questions to EDI technology as the core e-commerce will be a healthy development.
