Abstract
Privacy preservation is an important challenge for wireless health monitoring system. This paper analyses the privacy threat types based on the wireless health monitoring system architecture, and built the key system model for identity threat and context privacy preservation based on traffic analysis threat. To resist these threat , the integrated message encryption, identity authentication and traffic context privacy preservation, based on identity-based cryptography(IBC) and identity-based signature(IBS), is carried out at one time during the process of sending, receiving and accessing the patients' health information. Extensive analysis demonstrates the effectiveness of the proposed scheme.
