Comparative Study of Elliptic Curve Cryptography Hardware Implementations in Wireless Sensor Networks

Abstract

A comparative study of hardware implementations of Elliptic Curve Cryptography (ECC) in Wireless Sensor Networks (WSN) is presented in this paper. The study covers important parameters like the underlying finite field, representation basis, occupied chip area, consumed power, and time performances of these implementations. Additionally, most of the reviewed implementations were implemented on Application Specific Integrated Circuits (ASIC) and only one was implemented on Field Programmable Gate Array (FPGA). Likewise, most of these implementations were implemented over the binary fields GF(2) and using polynomial basis
