Trust management of services (TMoS): Investigating the current mechanisms

Abstract

Generally, service interactions in dynamic environments comprising cloud computing, Internet of Things (IoT), and etc. occur in an unspecified situation causing trust management a significant aspect. The widespread usage of services in today's vastly high-tech world reveals the rising necessity of trust management in terms of services. In dynamic environments, there are not enough confidences for users to recognize trustworthy service providers. Hence, evaluating and managing the trustworthiness of services is a vital challenge for enabling customers to select trustworthy resources in dynamic environments. To the extent of our knowledge, in spite of the vital role of Trust Management of Services (TMoS), there is not any thorough and systematic work in this scope with a specific focus on services. Thus, this research investigates the current methods of trust management in terms of services, which are published up to February 2020. We have identified 68 papers that are diminished to 22 mostly qualified papers through the article selection process. Also, we have examined and compared the selected papers in terms of their merits and demerits, considering the important parameters in this field. The investigation results point out that the security, scalability, and dynamicity are essential to almost all research. Furthermore, privacy and reliability are the most essential parameters in the field of TMoS. Moreover, the statistical results and information can contribute to future works; also, we have conducted some open issues and future work suggestions that could be an effective roadmap for future researchers in this area.

Dynamic QoS/QoE-aware reliable service composition framework for edge intelligence

“…With the growth of technology, service consumers’ demands are becoming more complex [ 23 ]. Thus, since a single service cannot satisfy them, the system needs to employ several different services to accomplish a request.…”

Blockchain based Decentralized Trust Management in IoT: Systems, Requirements and Challenges

“…In IoT scenarios, where there are a vast number of service providers, IoT objects (service requester or clients) are seriously concerned about the identification of most proper service providers. In dynamic environments of IoT, it is vital for enabling consumers to select trustworthy resources since confidences for users are not enough for recognizing trustworthy service providers and dishonest service suppliers are capable of tricking the unaware clients or service requesters [85]. in such a situation, TM plays a significant role in evaluating and managing the trustworthiness of services.…”

Single‐objective service composition methods in cloud manufacturing systems: Recent techniques, classification, and future trends

“…The users are mostly interested in secure, trustable, and reliable services. 62 Moving computational and storage closer to the end devices can be another roadmap for the future. This idea can be achieved by adopting edge computing 63 technology, which can contribute to the reduction of latency, response time, and energy consumption alongside the improvement in reliability and availability.…”
