Abstract
|
The security of wireless body sensor network (BSN) is very important to telemedicine and m-healthcare, and it still remains a critical challenge. Traditional security mechanism of wireless sensor networks can't be applied to BSN directly due to limited resources in terms of power consumption, computation complexity, and memory size etc. In this paper, a novel biometrics based cryptosystem, including the key generation, low power data encryption and integrity protection approach, is proposed for BSN. The frequency domain analysis ofECG signals is used to generate the relevant cryptographic keys. AES as a stream cipher are adopted to encrypt data and protect data integrity. Our biometrics based security solution can save the resource and satisfy the BSN security requirement in the mean while from the comparison in terms of power consumption and memory occupation between the stream cipher mode of AES and RC4.
