An Efficient Objective Intelligibility Measure for Frequency Domain Scramblers

EURASIP Journal on Information Security volume 2007, Article number: 032028 (2008) Cite this article

Abstract

An objective performance measure is proposed to evaluate the intelligibility of a speech signal having its frequency subbands permuted. The proposed tool can be used to generate efficient keys for frequency domain scramblers as well as to assess the results of cryptanalysis.
