The emergence of Internet of Things (IoT) technology brings tremendous benefits to people's lives and work.However, the integration of IoT devices into diverse systems has underscored the pressing issue of security.Safeguarding data confidentiality in IoT systems necessitates the implementation of strong security measures, including authentication, encryption and access control mechanisms.When effectively employed, these measures pave the way for the development of an efficient and secure IoT system, offering substantial benefits to end-users.This paper introduces a novel authentication and access control solution tailored for IoT edge devices.Our suggested approach is applicable to the edge network comprising numerous nodes, enabling the transmission of extensive data within constrained bandwidth based on lightweight symmetric cryptography since it uses Chacha20 algorithm to establishing session key, and maintaining the protocol of identity management and access control more precisely through HoBAC and blockchain technology.We have successfully analyzed the protocol correctness using the scyther tool.The results demonstrate the superiority of the proposed protocol compared to alternative approaches, particularly in terms of communication and time costs.
