Abstract—With the development of network service technology such as grid computing, cloud computing, the cooperation among multiply domains is needed for these intelligent services that have the unlimited space and the unlimited speed. This paper proposes a new union authentication protocol of cross-domain that can ensure the security of resource access in different domains, where the register keys of members in one domain are submitted to the key authentication center, rather than the private keys. This authentication protocol can avoid the shortcoming that it is complex to deliver certification in the traditional crossdomain authentication based on PKI and prevent the authority counter from pretending to be a member to access resources in other domains in the current identity-based authentication. The performance analysis shows that the proposed authentication protocol has good anonymity and can track the entities when there are the inconsistent cases. At last, a prototype system that can implement the authentication protocol is given.
