Blockchain-based group signature for secure authentication of IoT systems in smart home environments

Abstract

ABSTRACT Current solutions that rely on a single-server architecture have privacy, anonymity, integrity, and confidentiality limitations. Blockchain-based solutions can address some of these issues but face challenges regulating behaviour and protecting access policy privacy. This study proposes a new approach to securing a smart home environment to overcome these limitations.The proposed architecture is based on a group signature scheme, which allows multiple IoT devices to securely exchange keys and authenticate each other without needing a central authority. Our experimental results indicate the effectiveness and efficiency of the proposed architecture and provide insights into its security and privacy features compared to existing IoT authentication methods.
