The increasing prominence of wireless ad hoc networks is stimulating greater interest in developing adequate security mechanisms for securing applications involving these innovative networks paradigms. Adapting wired network security schemes-particularly those involved digital certificates-to wireless ad hoc networks environments, poses many difficulties, primarily for two reasons: the limitation of computational resources, and the absence of centralized entities for performing critical key management tasks such as certificate revocation. This paper proposes a certificate revocation scheme for wireless ad hoc networks. Their revocation scheme not only provides a measure of protection against malicious accusation attacks, but it also effectively eliminates the window of opportunity whereby revoked certificates can be used to access network services.
