Trust-Based Composition of M2M Application Services

The end-user integration for M2M application service creation and the decentralisation of M2M application service platforms are creating new possibilities for different application fields in the M2M domain. However, besides several advantages, these improvements inherit several security-related issues such as intentionally or accidentally misconfigured M2M application services harming other end-users in the M2M community. This research focuses on evaluating the trustworthiness of new joining decentralised M2M application services provided by end-users. Therefore, this publication presents a novel concept for trust evaluation by combining several model-based testing techniques. Moreover, it defines an approach for trust-based M2M application service selection and composition for end-user consumption. Finally, the overall framework for functional verification and trust evaluation is optimised by full decentralisation of all involved entities.
