Confidentiality-Preserving Personal Health Records in Tele-Healthcare System Using Authenticated Certificateless Encryption
摘要
Wireless Medical Sensor Networks (WMSN) facilitate the traditional healthcare systems, however, due to the public transmission, the healthcare system in WMSN also faces some serious security and privacy challenges. These are major concerns in the Health Insurance Portability and Accountability Act. Especially, integrity and confidentiality of patient physiological data are two key issues in privacy protection, which must be considered and ad- dressed firstly. Therefore, the security and privacy in such systems should be enforced via authentication as well as encryption. This paper presents an authenticated certifi-cateless public key encryption scheme for protecting the integrity and confidentiality of the patient sensitive in- formation in tele-healthcare system simultaneously. The security of this protocol is based on the hardness of the bilinear Difie-Hellman problem, and we prove that it is secure in the random oracle model. Our analysis and com- parisons with related protocols show that this scheme is a viable encryption for tele-healthcare system.
