Efficient key cryptography based on Body Area Networks

In order to reduce the amount of the data transformation and energy consumption in the key generation technology with biometric information, the Fuzzy Matching Curve (FMC) algorithm is proposed in Body Area Networks (BANs). We use a curve to fit these true points, transfer the parameters of the curve and achieve an efficient key cryptography scheme, while the Fuzzy Vault scheme hided the true points by adding randomly chaff points during the process of key generation. Experimental result shows that as compared to the encryption technology of Fuzzy Vault, the FMC algorithm not only reduces the amount of data required for generating the key and the computational complexity in a large extent, but also achieve real-time require in BANs.
