Realizing a Secure Federation of Multi-institutional Service Systems
نویسندگان
چکیده
This paper proposes an extended framework for service provision for ubiquitous spaces based on Kerberos. The framework allows groups of services and information about ordinary users that are managed on an organizational or personal level to be combined, handling service systems with different management bases as units of Space, while defining the security relations between different spaces. A combination of spaces merges two spaces on equal terms allowing the spaces to use each others services, while a fusion of spaces represents a power-relationship where one space are allowed to use resources in another space.

Enhancing Multi-Agent Systems with Peer-to-Peer and Service-Oriented Technologies
Peer-to-peer and service-oriented technologies have emerged as the dominant means for realizing scalable and interoperable distributed applications. This incontrovertible fact seems to nullify the expectation of multi-agent system researchers that agents could play a fundamental role in realizing such applications. However, from a deeper analysis, it is plain that neither peer-to-peer nor servi...
متن کاملPrivacy-preserving GWAS analysis on federated genomic datasets
BACKGROUND The biomedical community benefits from the increasing availability of genomic data to support meaningful scientific research, e.g., Genome-Wide Association Studies (GWAS). However, high quality GWAS usually requires a large amount of samples, which can grow beyond the capability of a single institution. Federated genomic data analysis holds the promise of enabling cross-institution c...
متن کاملMulti-Objective Lead Time Control in Multistage Assembly Systems (TECHNICAL NOTE)
In this paper we develop a multi-objective model to optimally control the lead time of a multistage assembly system. The multistage assembly system is modeled as an open queueing network, whose service stations represent manufacturing or assembly operations. The arrival processes of the individual parts of the product, which should be assembled to each other in assembly stations, are assumed to...
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...
متن کاملSemantically Federating Multi-agent Organizations
We believe that successful co-operation between multi-agent systems providing services in a specific domain can be realized by constructing an infrastructure that supports the semantic interoperability between them. In this paper, we introduce a conceptual architecture for the semantic interoperability of multi-agent systems in the large-scale. The most important element of the proposed concept...
