This paper presents the design and implementation of an efficient elliptic curve (EC) based key management scheme for wireless sensor networks in applications with high security concerns.The schemes available in literature are well analyzed and integrated architecture for two EC based key management protocols are developed and compared.The basic functions of authentication and random number generation are implemented using EC based algorithms instead of standard algorithms such as SHA or AES for optimized design of overall structure through hardware reuse.The proposed architectures are implemented over GF(2 163 ) on a Kintex 7 FPGA board using Xilinx ISE.The EC point multiplication is done using Lopez-Dahab algorithm and the finite field elements are represented using Gaussian normal basis to reduce the computational complexity and resist side channel attack.
