Abstract
This paper presents the results of a simulation of an analog encryption scheme. The scheme, introduced in 1979 by Aaron Wyner of Bell Telephone Laboratories, provides secure, accurate scrambling of speech waveforms, while conforming to the bandlimitedness of a telephone channel. The simulation confirms the scheme’s theoretical properties, based on numerical measures and on listening to encrypted and decrypted waveforms.
