Abstract: This paper proposes a key agreement protocol in satellite network based on bilinear pairings. It analyzes the characteristics of the satellite network and gives the implementation procedure of the protocol. Security analysis demonstrates that the key agreement protocol can resist active and passive attacks without key trusteeship problem and the key generating process is uncontrolled. Performance analysis demonstrates that the protocol can increase the efficiency of the session key agreement, it is more satisfied with needs of key generation in real satellite network.

Key words: satellite network, bilinear pairings, discrete logarithm problem, key agreement, active attack
