Trust is one of the most concerned obstacles for the adoption and growth of cloud computing. Although several solutions have been proposed recently in managing trust feedbacks in cloud environments, how to determine the credibility of trust feedbacks is mostly neglected. In addition, managing trust feedbacks in cloud environments is a difficult problem due to unpredictable number of cloud servi...

Trust management is one of the most challenging issues in the emerging cloud computing. Although many approaches have been proposed recently for trust management in cloud environments, not much attention has been given to determining the credibility of trust feedbacks. Moreover, the dynamic nature of cloud environments makes guaranteeing the availability of trust management services a difficult...

Trust management is becoming crucial in open systems because they may contain malicious and untrustworthy service providers. Trust management in multi-agent systems (used to model open systems) has gained a huge amount of attention from researchers in recent years. In our previous work, we proposed a generic agent trust management framework, called ScubAA, which is based on the theory of Human ...

Trust is an essential component for secure collaboration in uncertain environments. Trust management can be used to reason about future interactions between entities. In reputation-based trust management, an entity’s reputation is usually built on ratings from those who have had direct interactions with the entity. In this paper, we propose a Bayesian network based trust management model. In or...

To secure a wireless sensor and actuator network (WSAN) in cyber-physical systems, trust management framework copes with misbehavior problem of nodes and stimulate nodes to cooperate with each other. The existing trust management frameworks can be classified into reputation-based framework and trust establishment framework. There, however, are still many problems with these existing trust manag...

The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...

Nowadays, peer-to-peer (P2P) streaming systems have become a popular way to deliver multimedia content over the internet due to their low bandwidth requirement, high video streaming quality, and flexibility. However, P2P streaming systems are vulnerable to various attacks, especially pollution attacks, due to their distributed and dynamically changing infrastructure. In this paper, by exploring...

The rapid growth of communication technologies in the past years has enabled development of collaborative peer-to-peer applications. The reliable collaborative application must implement some methods which help to detect malicious entities and avoid collaboration with them. Such systems are based on building trust relationships between entities; their design is difficult due to a decentralized ...

The widespread use of the Internet signals the need for a better understanding of trust as a basis for secure on-line interaction. In this paper we provide and discuss existing works on trust management models in the area of Multi Agent Systems and highlight the shortcomings. Our proposed model is not presented as the final solution to the issue. This new model will have a mechanism that allows...

The entities participating in a context-aware service platform need to establish and manage trust relationships in order to assert different trust aspects including identity provisioning, privacy enforcement, and context information provisioning. Current trust management models address these trust aspects individually when in fact they are dependent on each other. In this paper we identify and ...
