Original scientific paper In the past decades, several trust models have been proposed to enhance the security of Mobile Ad hoc Networks (MANETs). The conventional trust models fail to express the notion of uncertainty during the establishment of trust relationships between mobile nodes. Furthermore, they lack in considering the context attributes in trust evaluation. This paper proposes a subj...

In a complex dynamic cloud computing environment, both analyses of abnormal behavior of users and confirming incredible users are effective security measures. Fuzzy mathematics is used to reflect the ambiguous judgment of experts, and AHP method is used to compute the weight for each attribute of network users’ behavior. So a comprehensive way is used to evaluate user’s trust value based on FCE...

Mobile ad hoc networks (MANETs) have been utilized to execute many applications in diverse environments. Trust is an effective mechanism to cope with misbehaving nodes. However, implementing trust in MANETs is confronted by several obstacles, i.e., no centralized authority, dynamic environments, and limited observations which hinder trust accuracy. In this work, we propose a novel logit regress...

The trust solutions to routing networks are faced with the evaluation of behavior trust and how to exactly evaluate the behaviors under the circumstance of existing recommend deceptive behavior such as providing fake or misleading recommendation. In this paper, by learning trust relationship from routing network, a trust evaluation model based on Grey Clustering Theory is proposed. The model ad...
