Research on Hierarchical ID-based E-government Grid Authentication Model
基于分层身份的电子政务网格认证模型研究

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 Authentication Model) based on HIBC.HIAM overcame the efficiency drawback of PKI-based authentication mechanism,combined with security service of GSI,and was feasible to deploy.
