A heterogeneous cross-domain authentication model based on access Tickets in virtual cable television network

摘要

The virtual cable television network is a cable television system with virtual assets, users in the network may have different authentication mechanisms. In order to meet corporate users across heterogeneous virtual, trusted domain request service is required. This paper proposes a bill based on the access authorization authentication scheme across heterogeneous domains. The scheme is based on VCA certification model, the Kerberos AS and the PKI domain as the domain where the CA Enterprise Domain external authentication node, generate its extracellular domain users access, the domain resources authorization bill and the session key, and then realize PKI and Kerberos cross-domain authentication, domain user and session key agreement. Article on the safety and efficiency of the program are analyzed. Analysis shows that this scheme can resist various attacks, with high security, and higher than the efficiency of alternative solutions for virtual cable television network, efficient resource sharing of cross-domain security provides an effective solution.
