Introduction to Laboratory Research : Evaluation of a Distributed Key Certification using Accumulators in very Constrained Wireless Sensor Networks

In this work we demonstrate that the distributed key certification accumulator based protocol proposed in [1] works well on low-power and memory constrained devices such as WSN430 and MB851 sensors. We observed that in large-scale sensor networks, accumulators based on elliptic curve cryptography (ECC) are much more convenient to use than secure Bloom filters because of their larger memory footprint. Obtained times of computation are very promising, and totally acceptable. In small-scale networks, computations using Bloom filters are faster than with ECC-based accumulators.
