摘　　要：为保障空间信息网络认证与密钥分发的安全性,本文提出了一种基于椭圆曲线密码系统的公钥管理方案,提供入网认证、密钥协商和密钥更新等功能,实现了认证性、抗重放和前向/后向安全性等多种安全目标。对于卫星间的认证和密钥协商,本方案仅需卫星之间进行3次交互即可完成。通过对方案进行安全性和效率分析,证实了本方案在空间信息网络中的实际可用性以及同现有公钥管理方案相比效率上的优越性。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 security.For interstellar authentication and key agreement,our scheme only requires 3 interactions between the satellites.We provide a security 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.
