Design and Analysis of The Public-key Management Scheme for The Space In-formation Network
To ensure the security of authentication and key distribution in the space information network,this paper proposes a public-key management scheme based on the elliptic curve cryptosystem.With the capacity for network access authentication and key agreement/update,this scheme can achieve various security goals,such as authenticity,anti-replay,and forward/backward securi-ty.For interstellar authentication and key agreement,our scheme only requires 3 interactions between the satellites.We provide a se-curity and efficiency analysis for our scheme,and show that the proposed scheme not only satisfies the actual availability in the space information network,but also performs better than other existing public-key management schemes.
