Secure and auditable agent-based communication protocol for e-health system framework

Security is essential for e-health system as it provides highly sensitive distributed medical data and exchanged among the healthcare professionals, customers and providers over Internet. Internet is an open access system that allows anyone to participate and access the data. Hence, it is necessary to protect the data, service from the unauthorized visibility, use and also maintain a high degree of accessibility. It is achieved using suitable access control policies and techniques that enforce differentiated levels of service visibility and access to the users. This paper introduces a Secure and Auditable Agentbased Communication Protocol (SAACP) which performs on key exchange mechanism with mobile agents to reduce the delay in communication. Intelligent mobile agents are proposed for dynamically negotiating the policy of the users. This protocol offers user friendly, privacy and safe communication through well-built secure mechanism that gives confident to the users and healthcare professional to access the e-health system.
