An RSA based certificateless signature scheme for wireless sensor networks
Jitendra V. Singh, Vimal Kumar, Rakesh Kumar · 2015
Due to wide need of wireless sensor networks in environmental monitoring, medical, military, and agriculture, to keep these networks secure and authenticated is very important. Certificateless cryptography is an efficient approach studied widely because it eliminates the need of certificate authority in public key infrastructure. There are no. of security algorithms based on PKC (Public Key Cryptography), ID based schemes certificateless schemes based on bilinear maps assumptions. But implementation cost of these schemes is very high. RSA is a scheme widely applied in real-life scenarios. In this paper we present a RSA based certificate less signature scheme especially for wireless sensor networks. Our scheme provide security against type I attack, type II attack, it also ensures integrity, nonrepudiation and authentication.
