摘要
在网格环境中,PKI公钥管理方式对GSI认证效率产生一定的制约,而基于IBC的认证机制轻量、高效,密钥管理较为简便,改进了TLS握手协议,在此基础上提出一种适用于电子政务网格的基于HIBC的认证模型HIAM(Hierarchical ID-based Authentication Model),该模型克服了基于PKI的证书认证机制效率方面的缺点,通过与GSI的结合,重用GSI提供的安全服务,同时便于部署。
In grid environment, the authentication efficiency of GSI is restricted by the key management methods of PKI. IBC-based authentication mechanism is lightweight, efficient and of more convenient key management. Therefore, this paper improved TLS handshake protocol and proposed a model named HIAM (Hierarchical ID-based Authentica- tion Model) based on HIBC. HIAM overcame the efficiency drawback of PKI-based authentication mechanism, com- bined with security service of GSI, and was feasible to deploy.
