Abstract
Wireless sensor networks (WSN) are composed of multiple sensor nodes with limited storage, computation, power, and communication capabilities and are widely used in various fields such as banks, hospitals, institutes to national defense, research, and so on. However, useful services are susceptible to security threats because sensitive data in various fields are exchanged via a public channel. Thus, secure authentication protocols are indispensable to provide various services in WSN. In 2019, Mo and Chen presented a lightweight secure user authentication scheme in WSN. We discover that Mo and Chen’s scheme suffers from various security flaws, such as session key exposure and masquerade attacks, and does not provide anonymity, untraceability, and mutual authentication. To resolve the security weaknesses of Mo and Chen’s scheme, we propose a secure and lightweight three-factor-based user authentication protocol for WSN, called SLUA-WSN. The proposed SLUA-WSN can prevent security threats and ensure anonymity, untraceability, and mutual authentication. We analyze the security of SLUA-WSN through the informal and formal analysis, including Burrows–Abadi–Needham (BAN) logic, Real-or-Random (ROR) model, and Automated Verification of Internet Security Protocols and Applications (AVISPA) simulation. Moreover, we compare the performance of SLUA-WSN with some existing schemes. The proposed SLUA-WSN better ensures the security and efficiency than previous proposed scheme and is suitable for practical WSN applications.

Summary
Wireless sensor networks (WSN) are widely exploited in terms of enormous applicability [1] and have been used in various fields such as smart homes, smart factories, healthcares, and environmental monitoring [2,3,4,5,6,7,8]. If data collected by SNs is exposed, a malicious adversary can obtain the private information of users such as daily routines and habits in the house, and can use the information for criminal purposes In these application scenarios, smart devices are resource-constrained in terms of computation, communication, and storage overheads, and it is not suitable to apply asymmetric. We prove that their scheme suffers from many drawbacks, including masquerade and replay and session key exposure attacks, and does not provide user anonymity, untraceability, and mutual authentication. Their scheme is not suitable for WSN environments because it requires high communication and computation costs. We propose a secure and lightweight three-factor authentication protocol for WSN (SLUA-WSN), considering the efficiency of smart devices and improving the security level of Mo and Chen’s scheme [15]
