This work presents a key management mechanism tailored to sensor networks called SENSORLock. Our main contribution is to propose, analyze, and demonstrate the feasibility of SENSORLock for secure symmetric key distribution solving the stored key exposure problem. Simulation results reveal that such mechanism introduces very low processing overhead, in the order of nanoseconds, and an estimated power consumption quite similar to existing approaches. Besides, practical experiments indicate that the scheme can be deployed by off-the-shelf sensors, such as MicaZ and TelosB.
