An XML Standards Based Authorization Framework for Mobile Agents
نویسندگان
چکیده
An outstanding security problem in mobile agent systems is resource access control, or authorization in its broader sense. In this paper we present an authorization framework for mobile agents. The system takes as a base distributed RBAC policies allowing the discretionary delegation of authorizations. A solution is provided to assign authorizations to mobile agents in a safe manner. Mobile agents do not need to carry sensitive information such as private keys nor they have to perform sensitive cryptographic operations. The proposed framework makes extensive use of security standards, introducing XACML and SAML in mobile agent system. These are widely accepted standards currently used in Web Services and Grid.

An Agent-Based Architecture Using XML for Mobile Federated Database Systems
We advocate the use of agents to model a system that allows us to integrate and protect information stored in both mobile and fixed devices, while trying to preserve a consistent authorization state. We propose a system called HAFS, which makes use of an object oriented access control data model to enforce security across the mobile federation and XML as a language to re present and exchange th...

This document defines a framework for authorization policies controlling access to application-specific data. This framework combines common locationand presence-specific authorization aspects. An XML schema specifies the language in which common policy rules are represented. The common policy framework can be extended to other application domains. Schulzrinne, et al. Standards Track [Page 1] R...
متن کاملA Policy Validation Framework for Enterprise Authorization Specification
The validation of enterprise authorization specification for conformance to enterprise security policies requires an out-of-band framework in many situations since the enforcing access control mechanism does not provide this feature. In this paper we describe one such framework. The framework uses XML to encode the enterprise authorization specification, XML Schema to specify the underlying acc...
