A secure and efficient user authentication protocol for wireless sensor network

Abstract

To provide the secure communication in wireless sensor networks (WSNs) is one of the challenging issues as the channel used is wireless. User authentication is a mechanism which is used to provide the secure communication in them. In this paper, it is devised a secure and efficient user authentication protocol using hash function for WSNs. It is formally analyzed the security of the proposed protocol using random oracle model and showed informally that it is resistant to various known attacks. Its security is formally verified using AVISPA tool. Its performance analysis along with the related schemes is evaluated in terms of security features, computational, communication, storage, and energy consumption costs. It has computational cost of 9 ms and storage cost of 30 bytes, which are less than the related schemes. Also it is more secure than them.
