Web Service Trust: Towards A Dynamic Assessment Framework

Spanoudakis, G. and LoPresti, S. (2009). Web Service Trust: Towards A Dynamic Assessment Framework. Paper presented at the International Conference on Availability, Reliability and Security, 2009. ARES '09, 16 - 19 Mar 2009, Fukuoka Institute of Technology, Fukuoka, Japan.

Abstract

Trust in software services is a key prerequisite for the success and wide adoption of services-oriented computing (SOC) in an open Internet world. However, trust is poorly assessed by existing methods and technologies, especially in dynamically composed and deployed SOC systems. In this paper, we discuss current methods for assessing trust in service-oriented computing and identify gaps of current platforms, in particular with regards to runtime trust assessment. To address these gaps, we propose a model of runtime trust assessment of software services and introduce a framework for realizing the model. A key characteristic of our approach is the support that it offers for customizable assessment of trust based on evidence collected during the operation of software services and its ability to combine this evidence with subjective assessments coming from service clients.
