Lightweight Biometric Key Agreement Scheme for Secure Body Sensor Networks

pdf PDF


A biometric sensor device is the potential product of the forthcoming biotechnology for real-time tracking of physiological signals to support various healthcare and medical services such as homecare medical service, prevention, diagnosis, and follow-up services. A key agreement scheme between biometric sensor devices is a fundamental requirement to support the security of the healthcare and medical services. Existing key agreement schemes employ high computational cryptography mechanisms or share a pre-deployed key among biometric sensor devices. Due to stringent constraints of hardware capability, it is inadequate to use public cryptography mechanisms for biometric sensor devices. Moreover, it is also inappropriate to install a fixed secret key in implanted devices because, if the key is revealed, a person will have inevitable transplantation surgery for the secret redistribution. In this paper, we propose new lightweight key agreement scheme which requires only symmetric cryptosystem without a pre-deployed secret information for biometric sensor devices.
