Abstract

Secure communication is an open challenge for Ubiquitous Sensor Network (USN) collecting valuable information. Sensor nodes have highly constrained resources like limited battery power, memory, processing capabilities etc. These Limitations make infeasible to apply traditional key management techniques such as public key cryptography or other complex cryptographic techniques in the USN. Based on polynomial key pre-distribution protocol, we propose a novel key predistribution technique to establish a pairwise key between sensors. In our scheme, we adopt the Probabilistic Randomness concept on the basis of Grid Based Scheme in a way to achieve improved resiliency over large number of node compromise compared to the existing key predistribution schemes. Beside substantial improved resiliency, it also provides high probability and efficiency in establishing pairwise keys both in direct or path discovery method. Security analysis shows the effectiveness of our scheme in terms of resiliency improvement with little additional overheads in memory and communication.
