Toward trust based protocols in a pervasive and mobile computing environment: A survey

In the blooming era of Pervasive and Mobile Computing, trust has been accepted as a vital factor for provisioning secure, reliable and seamless communications between pervasive computing elements. However, advancing research in the area of trust-based protocol for distributed Pervasive and Mobile Computing might be challenging due to the ambiguity of the concept of trust as well as the variety of divergent trust models, protocols and algorithms in different contexts. In this research, we augment the trust concept and definition from various field of studies and proposed models in the literature and provide general conceptual phases and methods of trust management toward-trust-based protocols, in the context of Pervasive and Mobile Computing. The paper addresses a broad range of techniques, methods, models, applications and desired futures of trust-based protocols. A number of the currently used trust-based protocols are critically reviewed, and this further leads our discussion to the security attacks and mitigation strategies used with trust-based protocols for pervasive and mobile computing. Finally, the paper discusses open research issues. (C) 2018 Elsevier B.V. All rights reserved.
