Abstract

With high-speed move and frequent cross-domain, the problem of certificate authority (CA) is a security bottleneck in the Satellite-Earth (S&E) Integration Network. A mobile-certificate authority Method based on PKI (Public Key Infrastructure) is proposed in this paper. Based on the RSA algorithm, the method realizes the anonymous authentication between neighboring nodes. It distributes the private key component to n nodes according to the threshold theory, and then realizes multi-node collaboration certification and dynamic permission-recovery. In addition, combining with distributed authentication and chain certification, this paper achieves distributed PKI and provides certification basis for high-speed nodes. This method frame, which is no-central, self-adaptive and traceable, could fulfill the quality of the S&E Integration Network. The experiments showed that the success rate and safety of it is much better than traditional distributed certification method. The method has far-reaching military value
