Architectures for Simultaneous Coding and Encryption Using Chaotic Maps

Amit Pande, Joseph Zambreno, Prasant Mohapatra

Abstract: In this work, we discuss an interpretation of arithmetic coding using chaotic maps. We present a hardware implementation using 64 bit fixed point arithmetic on Virtex-6 FPGA (with and without using DSP slices). The encoder resources are slightly higher than a traditional AC encoder, but there are savings in decoder performance. The architectures achieve clock frequency of 400-500 MHz on Virtex-6 xc6vlx75 device.
