Abstract

Delta and Delta-Sigma modulation methods have been getting a great
interest recently due to the great progress in analog-digital very large scale
integration technology. Since the outputs of these methods are digital, the
data can be securely encrypted using very simple standard hardware. In this
work, a chaotic random bit generator based approach for encrypting digital data
of the delta and delta-sigma modulators is studied. The chaotic bit generation
can easily be implemented in the digital hardware of the modulators due to simplicity
of the chaotic dynamics.  The randomness
of the generated chaotic bits are proved with visual and statistical tests. The
security of the proposed approach is evaluated via key space estimation based
attacks. The efficiency of the methods is validated with simulations.

Keywords
