| Abstract: | Existing Key management schemes for Ad Hoc networks usually use of threshold secret sharing cryptography so that the functions of traditional central services are shared and provided by all or parts of the nodes in the networks.This paper proposes a dynamiclly key management scheme(DKMS) based on bilinear pairing for Ad Hoc networks.The scheme can dynamically adjust shareholders and the secret sharing threshold by using secret redistribution.And by using the dishonest nodes of the network the verifiable secret sharing is detected and cleared.Thus it enables the network to have high security.The result proves that the scheme is correct,secure and robust for Ad Hoc network systems. |
