The Research of a Multi-Factor Dynamic Authorization Model
2012 IEEE Ninth International Conference on e-Business Engineering, 2012As there are always changes in trust level, organization structure, attributes of the subject, time strategy and so on, which will cause subject pemissions' change. The traditional static authorization based access control model is not appropriate in this condition.

Dynamic Authorization for 5G Systems
2018 IEEE Conference on Standards for Communications and Networking (CSCN), 20185G Networks are being designed to provide a diverse set of services using Network Slices (NS) that are enabled by Network Function Virtualization (NFV) and Software Defined Network (SDN) technologies. Given the expected diversity of service offerings and variety of connected devices, it's desirable to have a service authorization architecture that ...

Dynamic authorization and intrusion response in distributed systems
Proceedings DARPA Information Survivability Conference and Exposition, 2004 This paper presents an authorization framework for supporting fine-grained access control policies enhanced with light-weight intrusion/misuse detectors and response capabilities. The framework intercepts and analyzes access requests and dynamically adjusts security policies to prevent attackers from exploiting application level vulnerabilities.

Dynamic Authorization of Grid Based on Trust Mechanism
Web Information Systems and Mining, 2011In order to ensure the security of the sharing service in grid, a dynamic authorization model based on trust mechanism is presented, which is grounded on role-based access control. The model provides authorization while the trust worthiness of the bargainers exceeds the trade threshold, and it also introduces the concepts of task and condition into the
