Trust Metrics Model for Distributed System Access Control

Abstract

With the massive growth of Internet technology and data resources, the scale of entities involved in distributed systems and the complexity of the system continue to increase, and higher requirements are placed on the quality of data transmission. Provide support for the integration and integration of information resources and services. However, the access security of the system needs to be considered when sharing information, so it is necessary to implement access control on information resources to avoid computer access security problems. In this paper, a distributed system access control model system is constructed, and the inter-domain access control module is tested for concurrent access. The test results show that with the increase of concurrent access, the system response time and throughput change smoothly, and the system is relatively stable. In the simulation experiment of the trust quantification model, with the increase of the number of successful accesses, the trust degree will also increase; with the rejection of the access request, the trust degree will decrease.
