Continuous Authentication in Internet-of-Things Systems

Continuous authentication (CA) is a new approach to user authentication in distributed systems. Its main principle is that unlike a “traditional” approach, where a user is only authenticated once at the beginning of a session, in CA the user’s identity is re-verified throughout the entire session. In this paper, distributed system continuous authentication algorithms that can be used with IoT systems are investigated. They include methods using such technologies as Blockchain, machine learning, and biometrics. Based on the results of the analysis, a prospective CA algorithm is outlined.
