CERIAS Tech Report 2003-31 A FRAMEWORK FOR ROLE-BASED ACCESS CONTROL IN GROUP COMMUNICATION SYSTEMS
In addition to basic security services such as confidentiality, integrity and data source authentication, a secure group communication system should also provide authentication of participants and access control to group resources. While considerable research has been conducted on providing confidentiality and integrity for group communication, less work focused on group access control services...
متن کاملCERIAS Tech Report 2004-74 A FRAMEWORK FOR ROLE-BASED ACCESS CONTROL IN GROUP COMMUNICATION SYSTEMS
In this paper we analyze the requirements access control mechanisms must fulfill in the context of group communication and define a framework for supporting fine-grained access control in client-server group communication systems. Our framework combines rolebased access control mechanisms with environment parameters (time, IP address, etc.) to provide support for a wide range of applications wi...

Tripunitara, Mahesh V. Ph.D., Purdue University, December, 2005. A Theory Based on Security Analysis for Comparing the Expressive Power of Access Control Models. Major Professor: Ninghui Li. We present a theory for comparing the expressive power of access control models. Our theory is based on reductions that preserve the results of security analysis. Security analysis is an approach to the ver...
متن کاملGeneralized Temporal Role Based Access Control Model (GTRBAC) Part I Specification and Modeling
A temporal RBAC (TRBAC) model has recently been proposed that addresses the temporalaspects of roles and trigger-based role enabling. However, it is limited to constraints on enablingof roles only. We propose a Generalized Temporal Role Based Access Control model (GTRBAC)that is capable of expressing a wider range of temporal constraints. GTRBAC is capable ofexpressing periodic ...
متن کاملCERIAS Tech Report 2005-23 AN UPDATE PROTOCOL FOR XML DOCUMENTS IN DISTRIBUTED AND COOPERATIVE SYSTEMS
Securing data is becoming a crucial need for most internet-based applications. Whereas the problem of data confidentiality has been widely investigated, the problem of how to ensure that data, when moving among different parties, are modified only according to the stated policies has been so far not deeply investigated. In this paper, we propose an approach supporting parallel and distributed s...
