Research Status and Development Trends of Access Control Model
The main task of access control is to prevent unauthorized accesses to information resources.Conflict detection and resolution mainly solves problems caused by various security policies among different information systems.With the development of computer and communication technology
several access control models have appeared such as discretionary access control
mandatory access control
role based access control
task-based access control
access control for distributed environment and cross-domain
spatiotemporal attribute based access control and security attribute based access control
etc.The paper analyzes and summarizes the existing domestic and international research situation in the field of access control and conflict detection and resolution from the theoretical research and application aspects
indicates exiting problems in ubiquitous networks for the cyber-physical society
and points out some development trends of fine-grained and multi-level security access control model and scalable method for its policy.
