Hierarchical and declarative security for grid applications (2003) [4 citations — 3 self]
Abstract:
Abstract. Grid applications must be able to cope with large variations in deployment: from intra-domain to multiple domains, going over private, to virtually-private, to public networks. As a consequence, the security should not be tied up in the application code, but rather easily configurable in a flexible, and abstract manner. Moreover, any large scale Grid application using hundreds or thousands of nodes will have to cope with migration of computations, for the sake of load balancing, change in resource availability, or just node failures. To cope with those issues, this article proposes a high-level and declarative security framework for object-oriented Grid applications. In a rather abstract manner, it allows to define a hierarchical policy based on various entities (domain, host, JVM, activity, communication,...) in a way that is compatible with a given deployment. The framework also accounts for open and collaborative applications, multiple principles with dynamic negotiation of security attributes and mobility of computations. This application-level security relies on a Public Key infrastructure (PKI). 1
