Wireless sensor networks are use in wide range of applications, such as military, health, scientific, commercial. However, developing sensor network applications is obvious challenging issue, due to extreme resource limitations of nodes, the unreliability of radio communication, and the necessity of low power operation. This paper present pair wise key establishment scheme for wireless sensor network based on LU matrix, hash function and reverse function, which provide secure data exchange between the node and provide full resilience to node capture.
