Aiming at the problems of the existing single sign-on technology in the domain of Cross-domain authentication and stability, this paper designs a new identity authentication model, models the trust relationship between different identity management domains in the Cross-domain authentication, and makes clear the responsibilities and permissions of the members in each domain. At the same time, for the special requirements of cross-domain authentication, this research designs a set of off-line authentication method which is independent of domain protocol, and can conduct secure Cross-domain authentication in the case of the core node being off-line. Finally, this paper proposes a unified solution of Cross-domain identity, which allows users to unify their identities within different identity management domains. Based on the above research, this research designs and realizes the corresponding authentication protocol. The experimental results show that the identity authentication protocol designed by this research institute can deal with the problem of single sign-on between different trust domains and has excellent resistance to single point failure.
