Edge-cloud collaborative application scenario is more complex,it involves collaborative opera-tions among different security domains,frequently access-ing and exiting application system of mobile terminals.A cross-domain identity authentication protocol based on privacy protection is proposed.The main advantages of the protocol are as follows.1)Self-certified key genera-tion algorithm:the public/private key pair of the mobile terminal is generated by the terminal members them-selves.It avoids security risks caused by third-party key distribution and key escrow;2)Cross-domain identity au-thentication:the alliance keys are calculated among edge servers through blockchain technology.Cross-domain identity authentication is realized through the signature authentication of the alliance domain.The cross-domain authentication process is simple and efficient;3)Revocab-ility of identity authentication:When the mobile termin-al has logged off or exited the system,the legal identity of the terminal in the system will also become invalid imme-diately,so as to ensure the forward and backward secur-ity of accessing system resources.Under the hardness as-sumption of discrete logarithm problem and computation-al Diffie-Hellman problem,the security of the protocol is proven,and the efficiency of the protocol is verified.
