Revisiting Path-Key Establishment of Random Key Predistribution for Wireless Sensor Networks
Taekyoung Kwon, JongHyup Lee, JooSeok Song · Information Security and Cryptology · 2009
In this short paper, we revisit the random key predistribution methods for wireless sensor networks with regard to their intrinsic phase called the path-key establishment. First we show that the path-key establishment is less practical than expected and may degrade the performance of key establishment significantly. We then propose a novel path-key establishment method for those schemes and analyze its advantageous performance improvement.
