With the rapid deployment of the Internet of Things and cloud computing, it is necessary to enhance authentication protocols to reduce attacks and security vulnerabilities which affect the correct performance of applications. In 2019 a new lightweight IoT-based authentication scheme in cloud computing circumstances was proposed. According to the authors, their protocol is secure and resists very well-known attacks. However, when we evaluated the protocol we found some security vulnerabilities and drawbacks, making the scheme insecure. Therefore, we propose a new version considering login, mutual authentication and key agreement phases to enhance the security. Moreover, we include a sub-phase called evidence of connection attempt which provides proof about the participation of the user and the server. The new scheme achieves the security requirements and resists very well-known attacks, improving previous works. In addition, the performance evaluation demonstrates that the new scheme requires less communication-cost than previous authentication protocols during the registration and login phases.

<p>Wu-Chieu proposed an enhanced remote user authentication scheme to improve the security of a user-friendly remote user authentication scheme with smart cards. However, we demonstrate that their scheme is vulnerable and susceptible to the attacks and can easily be cryptanalyzed. Their scheme performs only unilateral authentication (only client authentication) and there is no mutual authentication between user and remote system, so their scheme suscepts from the server spoofing attack. Furthermore, their scheme is slower in detecting the wrong input-password, and users cannot change their passwords. This paper proposes an efficient and secure remote authentication scheme to solve the problems found in Wu-Chieu’s scheme. In addition, the computational costs and efficiency of the proposed scheme is better than other related published schemes.</p>
