Wireless sensor network is become more popular because of its various applications in day-to-day life. Communication security is one of the most important challenges in wireless sensor network. Key generation and distribution are also important in wireless sensor network, so the authors have effective security mechanism for that. Tree based key generation techniques uses shortest path matrix and MRD code matrix for key generation and distribution. It raises the security as well as scalability of the network than the other techniques.
