摘要

Wireless sensors are highly resource constrained in terms of memory, power and processing capability. However, critical applications of wireless sensor networks demand security features to be implemented. Further, when the thrust is miniaturization, provision of security features becomes challenging. Researchers have approached this problem and provided schemes such as SPINS, TinySec, TinyPK, Localized Encryption and Authentication Protocol(LEAP), Elliptical curve Cryptography(ECC), etc. TinySec is the most successful implementation to date. In this paper, we present some enhancements to the basic TinySec security features by providing an efficient key update mechanism on top of TinySec. The simulation results show that the memory overhead for this scheme is 1.66% and the computational cost is minimal. There is no latency or bandwidth overhead. Additionally to being feasible for implementation on current sensors, this scheme will be feasible on future miniaturized sensors with limited resources.
