Completely self-organization Ad hoc networks key management scheme based on elliptic curve

according to the current key management scheme exist large computation, trusted centre and key update cycle size is difficult to determine problems, we proposed a scheme that is based on ECC fully self-organization Ad hoc key management in this paper. The scheme use ECC instead of RSA for large computation; in order to solve trusted centre, we use fully self-organization; by using a double key update to overcome the regular updating cycle size problem. Computational cost of this program has a small computation safe, reliability and good scalability for large-scale Ad hoc network.
