Abstract
In this paper, present an efficient technique by ECG signal to generate 128 bit key from the peak value of QSR ECG value by the RSA Encryption algorithm. The 128-bit key generator using electrocardiogram (ECG) signals comprises two independent stages, namely, enrollment and verification-generation. This work is based on the uniqueness and quasi- stationary behavior of ECG signals with respect to an individual. The performance degradation over Rayleigh Fading channels is determined by the deep fades of the received signal power. RSA implements a public-key cryptosystem, as well as digital signatures. The Encrypted data will be transmitting over Rayleigh fading channel by OFDM system. Then the original data decrypted by the same technique with low SNR margin and Bit Error Rate (BER) rate. The BER performance of OFDM systems communicating over Rayleigh fading channels has been extensively studied and slow loss.
