Abstract

Abstract

The key management schemes bsaed on Distributed Certificate Authority resolve the difficulty to adopting concentrating key management in space networks, but result in some new threats of authenticated key. Based on discribing and analyzing the threats suffered by authenticated key of space networks, a measurement method for security intensity of authenticated key is proposed. The method can quantitatively measure the security intensity of authenticated key according to the setting of parameters, such as threshold value, key-update period etc. By analyzing the impact of threshold value and key-update period on authenticated key security, a method of setting the two networks security parameters reasonably is given.
