Efficient Pairing-Free Certificateless Signature Scheme for Secure Communication in Resource-Constrained Devices

Abstract

With the development of wireless communication technology, many network systems are interconnected with large number of smart devices and internet to gather and share electronic data. Due to its open nature, the data transmitted over public networks. Thus ensuring privacy and data security are of great importance. Also computing power, storage and bandwidth requirements are the main constraints in the development of many applications. To resolve these security and efficiency issues, this letter presents an efficient pairing free certificateless signature scheme. This scheme is proven secure and unforgeable. Finally, the comparative analysis shows the efficiency of our scheme.
