Abstract:

This paper proposes a secure identity authentication scheme for space-ground integrated network based on bilinear pairing. In the process of authentication, the two-way authentication between entities in the network can be completed without the participation of a third party, and the session key will be negotiated during the authentication process. The key provides confidentiality protection for the subsequent data transmission. In addition, the security of the proposed scheme is based on the elliptic curve discrete logarithm difficulty problem(ECDLP) and the elliptic curve computational Diffie-Hellman difficult problem(ECCDHP). It has high security and can defend against various forms of attacks. Finally, thisp paper conducts a theoretical analysis for the scheme of the feasibility and effectiveness.

Key words: space-ground integrated network, bilinear pairing, two-way authentication, key agreement
