Building on the q-composite random key pre-distribution solution, a single-group hash function-based key pre-distribution solution for wireless sensor networks is proposed. The key pre-distribution phase utilises the one-way feature of the Hash function to preload the keys, effectively hiding partial key messages of the nodes, and an assailant is only able to break the partial keys in the network by the backtracking mechanism through the key messages of the captured nodes. Both the results of theoretical and simulation analysis show that the scheme is more efficient than the q-composite scheme, obtaining higher resistance to capture attacks and reduced computational overhead, while guaranteeing the same network security connectivity, storage and communication capabilities.
