A HARMONIC BASED ENCRYPTION AND DECRYPTION SYSTEM FOR WAVEFORM SIGNALS

摘要

A method for securing a waveform signal for transmission by converting the signal into the frequency domain, applying an encryption function to the converted signal,and then by applying an inverse conversion to generate the final encrypted signal. The encryption function is a Vernon cipher, i.e. corresponding to a one-time pad. The process is reversed for decryption. Noise suppression, synchronization, and hardware parallelization techniques are presented.
