Study on Voice Password Based Secured Communication Using RSA and Elgamal Algorithm

EasyChair Preprint 3493

Abstract

Secured voice authentication based communication is the main objective of the study. Here eight speech keywords have been recorded and stored in computer memory. One speaker recognition model was used for voice password authentication. Subsequently, the speech keywords were encrypted using private key. The message was then, encrypted using RSA or Elgamal algorithm. The message was modulated using FSK digital modulation technique and sent through a communication channel. The speech samples were demodulated and decrypted at the receiving end. The received speech samples matched with the original transmitted voice samples. The equality ratio for this study is 0.6 and above. In this study, secured authentication technique has been adopted. After voice authentication, secured communication has been done successfully.

Keyphrases: Cryptography, ElGamal algorithm, RSA algorithm, speech recognition, voice password
