This paper presents a distributed user authentication scheme in wireless sensor networks. Our scheme is based on the self-certified keys cryptosystem (SCK), and we have modified i...
Secure communications in wireless ad hoc networks require setting up end-to-end secret keys for communicating node pairs. Due to physical limitations and scalability requirements, ...
Many key pre-distribution techniques have been developed recently to establish pairwise keys for wireless sensor networks. To further improve these schemes, researchers have propo...
— Key predistribution is a popular technique for key distribution in sensor networks. The schemes available in current literature using this approach are for nodes with no or lim...
— In Wireless Sensor Networks (WSNs), symmetric key schemes may be used to provide security. Recently, a class of random key pre-distribution techniques have been proposed and in...
