Secure and efficient ECC speeding up algorithms for wireless sensor networks

No image available for this title
Wireless sensor networks have been widely used in several applications ranging from environmental and health-care monitoring to military uses. Since sensor net- works are typically deployed in hostile environments, broad- cast authentication is a fundamental security service in wireless sensor networks. The slow signature verification in existing schemes always causes high energy consumption and long verification delay for broadcast authentication. In
this paper, we study the secure and efficient ECC speed- ing up algorithms for fast authentication in wireless sensor networks. We propose two fast algorithms based on con- strained triple base number system to improve the efficiency for situations with and without precomputations. These new
algorithms combine the sparsity of constrained TBNS with Yao algorithm to reduce the cost of scalar multiplication. Sev- eral experiments have been conducted using Magma software to assess the performance of the proposed algorithms. Our experiments show that the two algorithms are more efficient
than existing algorithms. Furthermore, the improvement of efficiency will reduce the energy consumption and thus pro-long the network lifetime due to the decrease of computation overhead in signature verification.
