A Biometric Key Establishment Protocol for Body Area Networks
Source: Hindawi Publishing
Current advances in semiconductor technology have made it possible to implant a network of biosensors inside the human body for health monitoring. In the context of a Body Area Network (BAN), the confidentiality and integrity of the sensitive health information is particularly important. In this paper, the authors present an ECG (ElectroCardioGram)-signal-based key establishment protocol to secure the communication between every sensor and the control unit before the physiological data is transferred to external networks for remote analysis or diagnosis.
