Secure group communication is one of the important secure services for the applications of wireless sensor networks because they are widely used in military as well as civilian operations. It is not very practical to assume the secure communication channels existing between group manager and each of its members just after the deployment, since most pair-wise key pre-distribution schemes in wireless sensor networks are connected with little probability. It means that it is probabilistically success for group manager and each of its members to build a secure communication channel using the pre-distributed pair-wise key at the initialization of wireless sensor networks. In this paper we propose the improved self-healing key distribution scheme which could add a strange node with coalition of t+1 group members. A so-called strange node is the node which has no secure communication channel with the group manager. We prove in an appropriate security framework that our scheme is self-healing with revocation property and extendable property under t+1 coalition. Finally, we provide a comparison in performance between our results and other existing solutions.

Keywords:Self-healing, Revocation, t+1 coalition, Group key distribution, Wireless Sensor Network.
