【正文】 s facing emerce, in this based on security technology from the perspective of development trend of emerce. Ⅱ . Emerce model Modern emerce technology has focused on the establishment and operation of the work of stores. Network in the department stores and real stores no distinction between structure and function, differences in their function and structure to achieve these methods and the way business operate. Web store from the front view is a special kind of WEB server. WEB site of modern multimedia support and a good interactive feature as the basis for the establishment of this virtual store, so customers can, as in a real supermarket pushing a shopping cart to select goods, and finally in the checkout check out. These online stores also constitute the three pillars of software: catalog, shopping cart and customer checkout. Customers use an electronic currency and transaction must store customers and stores are safe and reliable. Behind the store in the work, enterprises must first have a product storage warehouse and administration。然而，電子商務這種基于 Inter的開放式的數(shù)據(jù)交換是的其安全具有很大的脆弱性，安全問題是制約電子商務發(fā)展的一個核心和關鍵問題。其中建立安全認證體系是關鍵。作為一個安全的電子商務系統(tǒng)，首先必須具有一個安全、可靠的通信網(wǎng)絡，以保證交易信息安全、迅速地傳遞；其次必須保證數(shù)據(jù)庫服務器絕對安全，防止黑客闖入網(wǎng)絡盜取信息。 （ 3）加大對網(wǎng)絡安全技術的投入，提高網(wǎng)絡安全技術的水平。 。很多安全問題都存在技術的原因，所以更應該加大技術研究的資金，不斷推進舊技術的發(fā)展，并研究新的安全技術。 (一 )、加密技術 為保證數(shù)據(jù)和交易的安全、防止欺騙 ，確認交易雙方的真實身份，電子商務須采用加密技術，加密技術是指通過使用代碼或密碼來保障數(shù)據(jù)的安全性。網(wǎng)上交易的安全問題意味著： 有效性 :保證網(wǎng)上交易合同的有效性，防止系統(tǒng)故障、計算機病毒、黑客攻擊。網(wǎng)絡商店和真實商店在部門結構和功能上沒有區(qū)別，不同點在于其實現(xiàn)這些功能和結構的方法以及商務運作的方式。 Third, enterprises should also be responsible for product aftersales service, This service may be through works, may not. Inter transactions are usually a first Pay the bill and getting goods shopping. For customers, convenience is that the goods purchased will be directly delivered to their home, but hard to feel assured that the goods can not be confirmed until the hands reach into their own hands, what it is. Therefore, the credibility of the store work and service quality is actually the key to the success of emerce. Ⅲ .the key to development of electronic merce Emerce in the telemunications work to develop. Therefore, the advanced puter work infrastructure and telemunications policy easing the development of electronic merce has bee a prerequisite. Currently, tele services, high prices, limited bandwidth, the service is not timely or not reliable and so the development of emerce has bee a constraint. Speed up the construction of telemunications infrastructure, to break the telemunications market monopoly, introduce petition mechanism to ensure fair petition in the telemunications business, to promote working, ensure to provide users with lowcost, highspeed, reliable munications services is a good construction target work environment, but also all of the world mon task. Emerce the most prominent problem is to solve the online shopping, trading and clearing of security issues, including the establishment of emerce trust between all the main issues, namely the establishment of safety certification system (CA) issues。 we need to build em
