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.
