Advanced lightweight multi-factor remote user authentication scheme for cloud-loT applications

摘要

With the ongoing revolution of Internet-enabled devices, Internet of Things (IoT) has emerged as the most popular networking paradigm. The enormous amount of data generated from smart devices in IoT environment is one of the biggest concerns. Cloud computing has emerged as a key technology to process the generated data. The confidential data of user from IoT devices is stored in cloud server and the remote user can access this data anytime, anywhere and at any place from the cloud server. This makes remote user authentication a critical issue. This paper proposes a lightweight remote user authentication scheme for cloud-IoT applications. The formal security analysis using BAN logic and random oracle model confirms that the scheme is resilient to known security attacks. Furthermore, the scheme is formally verified using AVISPA tool which confirms the security against multiple security attacks.
