ASTP: Agent-Based Secure and Trustworthy Packet-Forwarding Protocol for eHealth
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011
Security has been recognized as a key issue for the expansion of eHealth application, where highly sensitive patient's medical data are routed through a non-secure wireless network. In this paper, we look into the various security and privacy requirements for the eHealth application and propose an agent-based secure and trustworthy packet-forwarding Protocol (ASTP) considering the neighbor nodes previous and recent activities. ASTP incorporated with proper security tools that enhanced the
... l performance of a cooperative multi-hop wireless network used for an eHealth application. The proposed protocol can successfully detects malicious nodes and the information is used and shared to the neighbors to avoid cooperating with them either for data forwarding, aggregation or any other cooperative function. Patient privacy is maintained by using an renewable pseudo-identity. Finally, security analysis and experimental results demonstrate that ASTP improves the average packet delivery ratio and maintains the require security and privacy at the cost of an acceptable communication delay.
