Heterogeneous Cross-Domain Identity Authentication Scheme Based on Proxy Resignature in Cloud Environment
2020
Mathematical Problems in Engineering
Based on proxy resignature, the signature transformation between trust domains of different cryptographic systems is realized with the help of the cloud authentication center, so as to achieve cross-domain access between users and cloud service providers in heterogeneous environment. Hierarchical ID tree realizes the uniqueness of identity in communication, and the security of heterogeneous cross-domain identity authentication is enhanced by the two-factor authentication of "password + key" and
