Abstract:

To tackle key management in sensor networks, we borrow concepts from natural biological systems to handle this problem, and a lightweight key management scheme which is applicable to smart dust sensor networks, key infection and evolutionm, is proposed. We first propose a probability model to analyze the security of the key infection protocol, and then introduce a new variant of the key infection protocol, Group based Key Infection, to improve its security performance. By combining key infection with a lightweight key pre-distribution scheme, a more secure key distribution scheme, Group based Key Infection with Key Pre-distribution, is proposed. To thwart on-going cryptanalytic attacks, a key evolution scheme with key synchronization is proposed to continuously renew shared keys. Analytical results show that the proposed scheme presents a viable trade-off between security and resource consumption for smart dust sensor networks.
