Security Management in Wireless Sensor Networks With a Public Key Based Scheme

Among several Public Key (PK) schemes proposed for Wireless Sensor Networks (WSNs), Elliptic Curve Cryptography (ECC) based algorithms have a proven and acceptable performance for low-powered sensor nodes. However, the use of certificates in such a scheme consumes a huge amount of bandwidth and power. Considering the constrained resources of sensors, here the authors propose an efficient PK-based security scheme for WSN. Their analysis and simulation results show that their scheme demonstrates good performance for the current generation sensor nodes.
