A Large-scale System Authorization Scheme Proposal Integrating Java, CORBA and Web Security Models and a Discretionary Prototype
نویسندگان
چکیده
This paper presents an authorization scheme for large-scale networks that involves programming models and tools represented by Web, Java and CORBA. The authorization scheme is based on structures and concepts introduced in Web, Java and CORBA for security. A discretionary prototype is presented here, where the solutions adopted involving a concrete scheme are discussed. This scheme was developed in order to simplify authorization policy implementation in these systems. These policies are based on well-known literature security models as the Access Matrix Model and on the discretionary policy objects of CORBA Security Specification.

متن کاملDistributed Systems Security
A distributed system is a set of autonomous units connected through some network. The most used distribution architectures are CORBA, DCOM, and RMI. CORBA is an architectural standard for interoperability of systems using different operating systems and languages. DCOM is Microsoft's distribution architecture for COM components. It only allows interoperation of Microsoft's systems. RMI (Remote ...
متن کاملAccess control in ultra-large-scale systems using a data-centric middleware
The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between sub-systems is increased, achieving more scalable and dynamic access control system becomes an im...
