Abstract
systems play an important role to achieve network security. Handling the issue of certificate revocation in wired network is somewhat easy compared to the MANETs. In wired network when the certificate of a malicious node get revoked then the certificate authorities add the information about the revoked node in to certificate revocation lists (CRLs) otherwise broadcast the CRLs to each and every node present in the network or either store them on accessible repositories. Whereas the certificate revocation is a challenging task in MANETs and also this conventional method of certificate revocation is not useful for MANETs due to absence of centralized repositories and trusted authorities. In this paper, we propose a threshold based certificate revocation scheme for MANETs which will revoke the certificate of malicious nodes as soon as it detect the first misbehavior of nodes. The proposed scheme also solves the improper certificate revocation which can occur due to false accusations made by malicious node also the problem of window of opportunity where revoked certificates get assigned as a valid to new nodes.
