Abstract: Utilising the Grid for conducting scientific research often involves a certain level of security risk, in particular when limited knowledge about the service provider is known before hand. This paper reports our experience of integrating an Attack-Tolerant Information Retrieval (ATIR) service with Taverna, a popular workflow tool among the UK e-science community, to support secure information query in a biology context. This paper presents the system architecture that has been used for the integration and the corresponding implementation details. Performance studies show that the overhead of ATIR server side processing is trivial ( < 5%) compared with the total processing time of the integrated Taverna. Our experimental results also show that the major processing overhead is caused by the Taverna enactor operations which consume no less than 50% of the total processing time.
