Authentication based elliptic curves digital signature for ZigBee networks

Abstract

Elliptic Curve Cryptography (ECC) is emerging as an attractive public-key cryptosystem, in particular for internet of things. Compared to the well known cryptosystems such as RSA, ECC offers equivalent security with smaller key sizes. In this paper, we propose an authentication mechanism based on ECDSA (Elliptic curve digital signature algorithm) signature for ZigBee networks. Our system guarantees an end to end authentication between communicating entities. Security analysis and performance evaluations show that our new mechanism is resource efficient and it can resist several kinds of attacks.
