A TRUST AND REPUTATION MODEL FOR WEB SERVICE SELECTION

摘要

With many enterprises moving towards a service-oriented architecture (SOA), the web service is becoming a standard method of sharing data and functionality. Furthermore, web service and service-oriented architecture are being also adopted by enterprises as a competitive advantage to drive business revenues. However, with an increasing number of services providing similar functionalities, it becomes critical for service oriented computing (SOC) to discover the trustworthy services so as to best fit the business needs. Hence a good web service selection mechanism with consideration of trust and reputation is the key component for successful operation of SOC [6]. Up to now, very few research results take all possible security scenarios into consideration, so the designed trust and reputation models may not function well all the time. The accurate and robust trust and reputation management mechanism should be able to effectively handle all possible threats. Hence, based on our earlier review of security threats [7], an adaptive and integrated model of trust and reputation is proposed.
