Security of SOA based on TPM

SOA has the characteristic of abstraction, loose coupling and interoperability, but there are some defect related to security and trust. How to specify and verify functional and non-functional requirements for service-oriented architectures had received much attention recently. This paper is to employ a hardware-based trust mechanism called Trusted Platform Module to bootstrap trust in a service-oriented architecture. This paper propose an architecture that serves to monitor remotely hosted web services and give an assurance about their integrity. The results show that it is feasible to effectively monitor web services in a service oriented architecture for privacy and integrity.
