A Random Key Management Scheme Based on Hash Chain in Wireless Sensor Networks
نویسندگان
چکیده
Key Management Scheme is an important factor to improve the safety performance of Wireless Sensor Networks (WSNs). The existing schemes can’t simultaneously meet the high demand of connectivity and anti-destruction to WSNs. We propose a key management scheme base on random Hash chain. The scheme firstly does multidimensional treatment for the key pool, and then uses a Hash Function to hash the key pool into several of key chains, which raises the relation among the keys. The high-relation makes any twice selection of key-set to contain one same key at least, which highly raise the connectivity of WSNs. Our scheme also deploys a small number of auxiliary nodes chain in WSNs. The chain will help WSNs to authenticate node identity and distribute keys among the isolated nodes. Simulation experiments demonstrate that the scheme not only raises the connectivity of WSNs, but also highly enhances the anti-destruction of WSNs.

The establishing of a pairwise key between two nodes for encryption in a wireless sensor network is a challenging issue. To do this, we propose a new deterministic key pre-distribution scheme which has modified the multiple key space scheme (MKSS). In the MKSS, the authors define two random parameters to make better resilience than existing schemes. Instead of a random selection of these parame...

An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
