Abstract:

Due to long time delay, broad coverage area, limited node capability and high mobility in mobile space self-organized networks, it is difficult to recognize the identity of node efficiently and safely. In order to solve the question, this paper put forwards a scheme based on random key graph, with which two nodes could prove the identity each other if they have a same edge from the random key graph based on DH protocol. At time, pre-configurationidentity authentication protocol is suggested for distributed networks, space entities get part of the material of identity authentication so as to recognize all legal nodes identity directly and indirectly according to parameters including network size, key graph scale, connective probability, and recognizing the legal identity of neighbor nodes successfully is a high probability event.So the scale of secret value for node identity can be lessened in the condition of guaranteeing the efficiency of identity authentication with increasing the number of certificates.

Key words: space self-organized networks, random key graph, identity authentication, regional autonomy
