The research proposed an approach that based on domain partitional Markov decision process to make decisions about the protection and defense against cyber attacks. We partitioned the network into several security domains. Markov decision models were made in each domain, with each state established by situational awareness. Strategy sets were set according to the system states. Cost-benefit factors...
Even though trust plays a significant role during decision-making in open collaborative environments, still end-user trust mechanisms have not be deployed in the EGEE grid computing setting. In this paper, we conduct a preliminary investigation on the integration of the trust paradigm in that environment, with a special focus on achieving end-user trust in an intuitive and practical manner.
Trust management is important for agent cooperation and security in multi-agent system. Based on rough sets theory, a new trust evaluation method is proposed. The method divides attributes into necessary or unnecessary, calculates attribute weight, and then evaluates trust values by using a decision-making method. Finally, an example shows that it is efficient to evaluate trust by using the method.
Information privacy typically concerns the confidentiality of personal identifiable information (PII) and protected health information (PHI) such as electronic medical records. Thus, the information access control mechanism for e-health services must be embedded with privacy-enhancing technologies. Role-based access control (RBAC) model has been widely investigated and applied to various applications...
