网格中基于身份的源可认证加密系统研究

Study of identity-based encryption and origin authentication for grid

研究了网格中加密系统,分析了已有的适用于网格的基于身份的加密系统,发现该系统存在设计上的安全漏洞,给出了一个基于身份的源可认证加密系统。该系统不仅能够保证信息的机密性、完整性,而且还能实现对密文来源的认证。

By analyzing the security of an existent system-identity-based encryption system for grid,the system was pointed out that it had some secure leak.To solve the problems of authenticating the user s identity,this paper proposed a new scheme was based on identity-based encryption.This system not only can protect data s confidentiality and integrality but also can authenticate the origin s identity.
