Design and implementation of RSA cryptosystem using multiple DSP chips

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.<
