Distributed Key Management for Ad Hoc Network
Li Xiao · Journal of Wuhan University · 2009
We briefly survey the recent works regarding key management of Ad Hoc network,and then analyze elliptic curve cryptography(ECC) that is appropriate for Ad Hoc network mainly owing to its smaller key size and a high security level.Following this lead,we further propose a practical distributed CA-based key management scheme for Ad Hoc network based on ECC,which includes key generation,new node entry and share refreshing.Finally,share refreshing of this scheme is simulated.The simulation proves that the scheme can improve the security,efficiency and robustness of Ad Hoc network.
