A Trust Model Based on Cloud Model and Bayesian Networks

Bo Jin, Yong Wang, Zhenyan Liu, Jingfeng Xue
2011 Procedia Environmental Sciences  
evaluation using bayesian networks Subject trust is a context-specific concept, but neither existing trust models based on cloud model consider context information explicitly.  ...  So, we propose a trust model to combine cloud model and Bayesian networks, which can represent and evaluate the uncertainty of trust more accurately and efficiently. 2.Trust representation using cloud  ...  We consider two context attributes and both have two states as described in previous section, so there are four different context situations.  ...

Trust and Regulation Conceptualisation: The Foundation for User-Defined Cloud Policies [chapter]

Jörg Kebbedies, Felix Kluge, Iris Braun, Alexander Schill
2016 IFIP Advances in Information and Communication Technology  
This work introduces a conceptual approach to user-centric policy management for cloud usage, combined with an underpinning holistic trust approach.  ...  Trust has to be established as a separate infrastructural concept determining the level of user adjustability.  ...  Once a root of trust is authenticated based on the trust policy, a security context is established through a Trust Point capable of enforcing cloud-specific policies in regard to this regulation layer.  ...
