Abstract

Information and Computing Sciences

virtual organization

business process

authorization architecture

chord protocol

In this paper, a distributed architecture has been proposed in order to support an authorization service more precisely in dynamically created Virtual Organizations (VO). In comparison with other existing architectures such as Akenti, VOMS and TAS, our architecture uses certificates on top of the distributed agent architecture for managing requested resources among the VOs. The most obscure issue in distributed agents is finding the proper node that keeps the particular requested certificates In this paper, Chord's Finger Table has been improved to add extra search abilities on the ring architecture of Chord. The process of locating keys can be implemented on the top of the improved Chord by associating a key with each data item, and storing the key/data item pair at the node to which the key maps. In this article, a theoretical analysis is presented for simulations, which shows improvement in the number of passed hops to locate keys in the proposed method in comparison of standard chord, so it's more cost efficient.
