Wireless sensor networks (WSNs) consists of small nodes with constrained capabilities to sense, collect, and disseminate information in many types of applications. As sensor networks become wide-spread, security issues become a central concern. In this paper, we identify the Security requirements of key management in WSN. The secure management of the keys is one of the most critical elements when integrating cryptographic functions into a system. An outline of hybrid cryptography, one way hash and Key infection schemes are discussed in this paper. Along the way we analyze the advantages and disadvantages of current secure schemes. Finally, we aim to provide efficient key management operations for secure communications in WSN.
