An Efficient Key Predistribution Scheme in Wireless Sensor Networks
Hangyang Dai, Hongbing Xu · 2007
For security services in wireless sensor networks, key management is a fundamental building block. In this paper, we propose a triangle-based key predistribution scheme by combining polynomial-based scheme and the triangular deployment model. The analysis in this paper indicates that our scheme can increase the probability of direct key establishment and that of indirect 2-hop key establishment by more than 10% over previous schemes.
