摘要
随着电子商务的不断发展及应用的深化,电子商务交易的安全性也越来越得到人们的重视。如何确保交易信息的保密性、完整性、真实性和不可抵赖性,已经成为迫切需要解决的问题。利用以公开密钥加密技术为基础的认证机构CA,及其颁发的数字证书,能够很好的解决上述问题,并保证交易各方身份的确定性。认证中心CA是电子商务交易中公正的、权威的第三方机构。
     本文围绕电子商务中的认证机构CA进行了探讨,包括加/解密技术、数字签名技术、认证机构CA的组成及其在电子商务中的地位和作用、数字证书概念和作用,我国认证机构的发展现状及存在的问题等,并对其中涉及到的一些问题进行了比较分析和思考,并提出了自己的观点。最后以网上证券交易为实例,提出了网上证券交易的身份认证解决方案,分别是建立证券公司企业级CA、建立RA和建立受理点,还对提出的三种可行方案进行了分析和比较。
With the development of the electronic commerce and the deepening of it's application, more importance is attached to the security of the online trading. How to insure the safety > confidentiality > integrity and non-repudiation of the trading information has become urgently to be solved. By using the public key infrastructure certificate authority and it's digital certificate, can solve the above problems, and at the same time can guarantee the reliability of people's identity. Certificate authority
    ( CA ) is the impartial, authoritative third party in the trading of electronic commerce .
    This thesis mainly discussed CA and something related to it in electronic commerce, including encryption and decryption algorithm
    ( DBS, RSA ), digital signature, digital certificate, the constitution and the function of CA in electronic commerce , the development status and the problems encountered of the CA in our country. After careful comparison and analysis, I propose some ideas and suggestions of myself. At the last chapter, by discussing the securities online trading, I propose three possible means to prove the investor's identity, they are: building CA of the stock company, building RA ( register authority) and building LRA (local RA) .
