Trustworthy Web Service-Business Activities (WSBA) using an Efficient Byzantine Fault Tolerance Algorithm

In order to provide the services related to coordination, all the stipulated Business Activities (WS-BA) rely on the Byzantine Fault Tolerance (BFT) based lightweight mechanism for trustworthiness. The main objective of this paper is to provide security and less overhead to the initiator. The ultimate idea of the proposed work is to deploy a trustworthy third party services for the entire coupling and coordination services for the multiple business activities of an organization or enterprises. It can also be executed using the cloud services which will be much easy for large scale companies. In this paper we use BFT algorithm which handles lightweight ordering of sources and provides a standard way of communication between the client and the actual system coordinator. It also deals with Web Services-Business Activities-Initiator service which resolves some issues related with the security to the initiator, coordinator and participants. We also use timestamp or nonce to provide security to the coordinator and the initiator during the request and response between them.
