Implantable medical devices (IMDs) are used to save a patient's life However insecurely designed IMDs can be life threatening Usually IMDs have low computational power and cannot be recharged which presents adverse conditions for IMDs Thus security is not only an important issue but also requires a tradeoff between efficiency and security To secure communication between an IMD and the hospital information system this study proposes a new biometric-based security scheme to protect the safety of patients equipped with IMDs In addition the concept of gregariously aggressive networked gears (GANG) is implemented which uses cooperative communication to enhance the efficiency and reliability of transmission Furthermore this research also proposes a new secure authentication and distribution scheme that links the IMD and wearable devices into a network of GANG To improve battery life and prevent tampering and disclosure attacks the members of this network establish mutual authentication and cooperation During communication a biometric key generator uses a physiological signal to generate a key using a deterministic random bit generator (DRBG) to enhance the security strength of the symmetric key Moreover it transforms the encrypted data into a chain for communication The gears of a GANG member should always react within the designated time when communicating with the IMD to ensure its high priority and detect any attack activities Finally through security analyses and experiments the proposed scheme is demonstrated to be feasible compared with existing schemes
