Abstract In order to resolve the problems of concentrating key management and over-consumption on certificate maintenance in space network, an identity-based distributed key management scheme is proposed. On the basis of the properties of space network, the method for constructing distributed private key generators is put forward. According to identity-based cryptography proposed by Boneh and Franklin, the scheme designs the methods of updating private key, updating host-key shares and negotiating session key. Analysis and simulation show that the scheme can meet the safety requirements and has good scalability.
