Abstract
E-health system has been used as communication system that enables to deliver medical service over the Internet. The medical information’s accessible in e-health systems are highly sensitive and distributed that demands strong authentication and authorization mechanisms for communication between the healthcare professionals, consumers and providers. Internet is an open system that provides global access without much constraint. Hence, e-health users demand safe communication and user privacy over the Internet. This paper introduces three secure communication protocols based on message passing and Mobile agent for online e-health system. Certificate based Authentication and Attribute based Policy assigned Authorization framework (CAAPA) for mobile users is proposed based on message passing technique. Token based Cross Verification (TCV) protocol is proposed for secure services in e-health System over Internet based on Mobile agent. Secure and Auditable Agent- based Communication Protocol (SAACP) performs on key exchange mechanism with mobile agents to reduce the delay in communication. Intelligent mobile agents are proposed for negotiating the policy of the users dynamically. All the above protocols offer user friendly, well-built secure mechanism that gives confident to the users and healthcare professional to access the e-health system. These protocols are efficient in terms of maintaining strong user privacy. CAAPA provides high communication overhead compared to other protocols.
