Secure Path Key Establishment for WSN

Several path key setup strategies make the assumption that node capture attacks are equally likely to affect every node in a wireless sensor network. However, in crucial applications like border surveillance and crisis management, this supposition might not hold true, making such schemes unworkable. In order to lower the issue of key exposure, this article suggests an attack matrix (AM) that determines the attack coefficient of sensor nodes based on where they are located in the sensor field. The disjoint path key establishment is an attack-resilient path key establishment method that is developed using the AM. The suggested scheme outperforms the current path key establishment technique in terms of performance, and the likelihood of key recovery and the path compromise ratio are used to confirm that they are resistant to node capture. The outcomes show how well the suggested strategies work to lessen the effects of node capture.
