Abstract
Security and privacy are the main concern for patients to seek wireless body sensor network monitoring their health. Considering the limitations of power, computation capability and storage resources, it is a big challenge to find out suitable secure scheme for patients when relying on wireless body sensor networks to monitor their healthy information. Many schemes based on asymmetric and symmetric have been investigated for such kind problems. In this paper, we present an authenticated identity-based key encryption scheme for patients to secure their healthy privacy based on wireless body sensor networks monitoring their health. We review briefly about identity-based encryption and decryption first, and then describe an authenticated key establishment and encryption scheme based on the basic Boneh-Franklin algorithm for wireless body sensor networks. Finally we compare the proposed scheme with other technique with analysis and simulations. The results show that the proposed scheme is efficient and secure.
