制造网格环境下无证书密钥协商方案

Certificateless key agreement scheme under manufacturing grid

为解决网格技术中证书管理的复杂性问题,提出了无证书两方密钥协商新方案。新方案使用了显示认证方法,在随机预言模型下新方案的安全性得到了证明。只要每方至少有一个未泄露的秘密值,那么新方案就是安全的。新方案适合制造网格多信任域环境需求。与其他制造网格环境下密钥协商协议比较,新方案在计算效率上占优。

Currently,certificate management is a complex problem in grid technology.To solve this problem,a novel certificateless two-party key agreement scheme was proposed.This scheme achieved explicit authentication,so its security under random oracle model was verified.It was secure as long as each party had at least one uncompromised secret.This new scheme was apt for the manufacturing grid environment under the multiple trust-fields.Compared with other key agreement protocols under manufacturing grid,the new scheme was more efficient in computing.
