With increased focus on wireless communications, Mobile Ad hoc NETworks (MANETs) are attracting much attention in recent years. MANET is an infrastructure less mobile network formed by a number of self organized mobile nodes which is different from traditional networks that has a fixed infrastructure. Certificate revocation is a major security component in mobile ad hoc networks. Because of their wireless and dynamic nature, MANETs are vulnerable to security attacks from malicious nodes. Certificate revocation mechanism plays an important role in securing a network. When the certificate of a malicious node is revoked, it is denied from all activities and isolated from the network.
