Abstract :
The authors present the design and implementation of an RSA cryptosystem using multiple TMS320E 15 DSP (digital signal processing) chips. The system developed consists of a stand-alone unit containing the DSP hardware and a high-level PC user-interface. The system is flexible and allows for additional DSP chips to be inserted in allocated slots to improve its performance. It also allows for trade-off between speed of encryption and level of security. The system was found to be 70 times faster than the same RSA algorithm implemented using C-language at PC level
