Abstract
Key management and authentication are essential modules for network security provisioning especially for Wireless Sensor Networks (WSN). Make available these two services by using symmetric cryptosystems in software implementation are challenging that’s not providing a perfect trade-off between resilience and performance. Asymmetric approaches with public key cryptosystems, specifically Elliptic Curve Cryptography (ECC) with implementation in hardware target can meet this challenge. The main focus of this paper is to provide a comprehensive use and comparative hardware implementation study of ECC for WSN security. In our study, we addressed the state of the art in research works related to ECC hardware implementations for WSN and discussed some enhancements and future works.
