Navigating Zero-Knowledge Authentication in the IoT Landscape: A Comprehensive Survey

Abstract

With the growing demand for Internet of Things devices and their usage in day-to-day life, security is the prime factor that needs to be considered. In Internet of Things devices, authentication factors such as biometric factors are usually sensitive in nature. There is a need for some strong authentication mechanism that ensures negligible data breaches in a system. Zero-knowledge authentication is a modern cryptographic technique that proves knowledge without its disclosure, ultimately boosting security by avoiding any kind of storage or exposing sensitive data. This paper aims to analyze the properties of zero-knowledge proof and how it helps in preserving the security of IoT devices. The paper not only discussed the IoT architecture and analyzed the design of zero-knowledge authentication in various Internet of Things networks but also mentioned the limitations and future directions.
