The Access Control Technology of Domestic Gateway in Nuclear Safety-Level DCS System

This paper discusses the important position of network security of domestic gateway in nuclear DCS information security from the perspective of nuclear power energy security. Currently, domestic gateway devices suffer from no connectivity restrictions, which can reduce their network security attributes. In order to solve the problem, this paper first demonstrates the positive significance of access control technology, then proposes an access control model that meets the requirements, and finally the model is verified theoretically and tested. The access control model proposed in this paper is expected to provide theoretical and practical application references for the development of nuclear power information security and promote the development of information security in the nuclear power industry.
