چکیده
We propose new fast implementation method of public-key cryptography suitable for DSP. We improved modular multiplication and elliptic doubling to increase speed. For modular multiplication, we devised a new implementation method of Montgomery multiplication, which is suitable for pipeline processing. For elliptic doubling, we devised an improved computation for the number of multiplications and additions. We implemented RSA, DSA and ECDSA on the latest DSP (TMS320C6201, Texas Instruments), and achieved a performance of 11.7 msec for 1024bit RSA signing, 14.5 msec for 1024-bit DSA verification and 3.97 msec for 160-bit ECDSA verification.

An efficient implementation of multi-prime RSA on DSP processor
RSA is a popular cryptography algorithm widely used in signing and encrypting operations for security systems. Generally, the software implementations of RSA algorithm are based on 2-prime RSA. Recently multi-prime RSA has been proposed to speed up RSA implementations. Both 2-prime and multi-prime implementations require squaring reduction and multiplication reduction of multi-precision integer...
