Internet of Things privacy security protection access control Research

The application of the Internet of Things will become more and more extensive, and solving the problem of access control of the Internet of Things nodes and the problem of privacy and security protection is the focus of current research in the field of Internet of Things security. This paper proposes an access control model based on a mixture of attributes and roles, which has a good security protection effect on the entire system. Aiming at the possibility of various types of privacy leakage in the information transmitted in the Internet of Things, a two-way authentication mechanism between the master node and the terminal base station is proposed. Analyze the mixed access control model of this article. Users check in to simulate the model of this solution. On this basis, simulation comparison analysis is simulated, attribute encryption and time constraints are introduced, which protects users ‘privacy and security, and solves the problem of The increase of roles takes up too much resources, causing uneven resource allocation and waste. Let attribute-based access control and role-based access control work together, which is in line with a safe and efficient access control model.
