A new pairwise key establishment scheme for sensor networks
Sujun Li, Siqing Yang, Suying Zhu, Fuqiang Yan · 2010
Due to resource constraints, achieving key management in sensor networks is non-trivial. In this paper, we propose a new pair-wise key establishment scheme based on the combination of pre-distribution scheme and Hash function. In our scheme, keys stored in a node which include two parts, the greater part are transformed by Hash function and the rest are come from the global key pool directly. Theoretical analysis and simulation results show that the proposed scheme can achieve a high local connectivity, a strong resilience against node capture at the cost of low storage overhead.
