Real time implementation of DES algorithm by using tms3206713 DSK

Abstract

The data encryption standard (DES) is an algorithm that was formerly considered to be the most popular method for private key encryption. DES is still appropriate for moderately secured communication. In this project I have implemented DES algorithm for voice data encryption by using the Texas Instruments TMS320C6713 dsp processor. TMS320C6713 is a 32-bit floating point dsp processor which is one of the Texas TMS320C6x family. Digital signal processors such as the TMS320C6x(C6x)family of processors are like fast special-purpose microprocessors with a specialized type of architecture and an instruction set appropriate for signal processing. The architecture of the C6x digital signal processor is very well suited for numerically intensive calculations. Based on a very-long-instruction-word (VLIW) architecture, the C6x is considered to be TI’s most powerful processor.
