Random key Pre-distribution scheme has been proposed to overcome the memory, computation and energy limits of individual sensor in wireless sensor networks. In this scheme, a ring...
Pairwise key establishment is a fundamental security service in sensor networks; it enables sensor nodes to communicate securely with each other using cryptographic techniques. Ho...
— Because of limited resources at sensor nodes, sensor networks typically adopt symmetric-key algorithms to provide security functions such as protecting communications between n...
Sensor networks are composed of a large number of low power sensor devices. For secure communication among sensors, secret keys must be established between them. The establishment...
