摘      要：In order to meet the authentication requirement of the revoking frequently and dynamic network environment,a revocation scheme for the cloud computing environment is proposed.The entering,leaving,revoking and authentication of entities are implemented based on the public key cryptography and the secure dynamic one-way accumulator,and the cross-domain property is also supported.The results show that the proposed scheme is provable secure to realize the identity authentication,session key agreement and key update with entity secrecy and perfect forward secrecy etc.In the cloud computing environment,compared with the existing schemes,this solution has a higher level of security,better performance and more comprehensive problem solving for revocation.
