Security is one of the core concerns in group communication in wireless sensor networks (WSNs). Secure group key management schemes are responsible for secure distribution of group keys among valid nodes in a group. We are representing a secure group re-keying scheme with compromised nodes revocation in WSNs. This scheme represents function of joining and leaving of nodes in a group. As WSNs are exposed to threats, so compromised node revocation is a challenging task. Our main focus is revocation of compromised nodes from a group without re-grouping. And also when a compromised node is revoked; it is unable to join any new group in future. In the scheme, we are updating the pre-deployed keys as well as current group keying material. Thus compromised node is unable to continue with current and future groups. Scheme is examined for verification of its computational and security requirement.
