| Abstract: Wireless sensor network (WSN) has unique nature which is different from other kinds of networks. It contains a large number of sensing devices which are limited in energy, computation power, and communication capabilities. WSNs are used in applications where the sensors have physical interactions with its environment and are accessible by any one. This makes them more vulnerable to various security threats. However, establishing secure communications is an open and difficult issue for WSNs. Exchanged information over WSN is to be secured by encryption and the use of an efficient key management protocol. Key management, in general, involves both the key establishment and key distribution. Traditional key management is difficult to apply in WSN due to its nature. In this paper, we present new protocol for key establishment and key distribution, referred to as cluster-based key management for WSNs, which is based on Eschenauer and Gligor (EG) key pre-distribution scheme. Our proposal covers the aspects of key generation phase using minimum number of keys generated in the pool, and re- keying phase using two key rings in each sensor node, to overcome the related drawbacks of the EG. | ||
