| Abstract | <p>We propose an access control scheme to improve the security of a cross border health data access running under distributed systems such as OpenNCP that cooperate through message exchanges. The scheme allows messages that request data and services to cross different regional or national nodes after they are verified for security issues both by the sender and the receiver. It rejects those access requests that are detected to be malicious, and consequently throttles down the flow of permit messages via explicit feedback from threat detection software placed at the sender and the receiver. An analytical model is used to evaluate the message delay to determine the overhead caused by the enhanced security system, and numerical results illustrate the impact of attack rates and on the system’s performance.</p> |
