基于云端计算的安全访问代理机制的研究

Research on security access proxy mechanism based on cloud computing

为了解决登录多种云端服务器需要管理多个账户和若干付款通道的问题,采用代理签章技术和椭圆曲线密码学,通过注册、预先计算、连线认证、离线认证四个阶段完成基于云端计算的安全访问代理机制。实现了单一账号登陆、离线认证功能、用户隐私保护、没有重复计费问题和登录密钥安全等技术要求,并降低了通信成本和计算成本。

In order to solve the problem when login multiple cloud server need to manage many accounts and several payment channels,this paper proposes a security access proxy mechanism based on cloud computing between the proxy signature and elliptic curve cryptography. It consists of registration, precomputing,line and off-line certification. It achieves single account login,offline authentication,user privacy protection,no duplicate billing issues,login key security,and reduces the communication costs and computational costs.
