Implementing a Trusted Service-Oriented Network Environment

Trust has become an important feature of security. Originally having its roots in the social sciences, it has fast moved into the field of computer science and more recently into the domain of network security. It is becoming important for scientists to model human trust, especially in a network environment where a lack of trust between network devices, such as routers, can result in poor quality of service and an increase in security compromises. In a network environment there is no “behaviour” indicator for routing devices about other devices on their forwarding path. Thus, relying on another routing device might be difficult if a secure and reliable service is not available. In this paper we present our ongoing implementation of trust in service-oriented network environments and explain how trust is implemented between network devices.
