基于小区体制的B to C 方案

摘要

针对小区体制，提出一种达到安全要求但不经CA(Certificate Authority)认证的B to C方案，引入一次一密的加密方法，即在传送信息中加入了不确定因素，每次传送信息所用的密钥都不相同，使密文在有限时间内难以破解且避免了固定密钥容易泄密的缺点。在本方案中，加密算法是公开的，密钥为解密的唯一方法。本方案具有运营成本低廉、实时快速的特点，特别适用于小区体制的网上购物。%A new scheme is advanced in the B to C commerce based on areola system where the trusted third party authorzation is not required. In the scheme, the idea of one encryption one time is proposed and the encryptional programme is opened and the key is kept only. So, the company economizes the cost and attain the security and the realtime according to the scheme.
