While caGrid 1.0 is designed to address use cases in cancer research, the requirements associated with discovery, analysis and integration of large scale data, and coordinated studies are common in other biomedical fields. In this respect, caGrid 1.0 is the realization of a framework that can benefit the entire biomedical community.
Grid systems have huge and changeable user groups, and different autonomous domains always have different security policies. The attribute based access control (ABAC) model, which is flexible and scalable, is more suitable for Grid systems. This paper describes a method of building a flexible access control mechanism that is based on ABAC and supports multiple policies for Grid computing. Firstly an attribute
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
