Abstract

Since identity authentication system itself has a certain degree of computational complexity, in order to achieve full homomorphic encryption, secure two-party computing protocol needs to be introduced, which will increase amount of additional computation and computational complexity. Therefore, a method is proposed in this paper to improve credibility by introducing feature vector model in power grid authentication, which is improved on the basis of IMSAKA. Moreover, it is an important way to improve security of access layer in IMS network through effective authentication and authentication on IMS network.
