Abstract
It is important to ensure the data security of biosignals transmitted by a wireless network. This paper proposes a mobile-care device using Tame Transformation Signatures (TTS), which is a digital signature scheme from the family of asymmetric public key systems to encrypt the electrocardiogram (ECG) data. TTS has the advantages of high security, fast key generation, complex algorithm, less calculations and low signature delay. The proposed system consists of a mobile-care device to measure ECG signal, a key center to generate key pair, and a monitor center. The proposed ECG mobile-care device adopts the TI MSP430F449 microprocessor as the kernel and generates 8-byte hash codes and 10-byte signatures to sign the data. And the mobile-care device transmits the signed data through a wireless network to the server to decrypt. This paper describes the design and implementation of the proposed system in detail and also completely verifies the validity of the proposed system.
