Techniques for Performance Improvement of Integer Multiplication in Cryptographic Applications

Abstract EN

The problem of arithmetic operations performance in number fields is actively researched by many scientists, as evidenced by significant publications in this field.

In this work, we offer some techniques to increase performance of software implementation of finite field multiplication algorithm, for both 32-bit and 64-bit platforms.

The developed technique, called “delayed carry mechanism,” allows to preventing necessity to consider a significant bit carry at each iteration of the sum accumulation loop.

This mechanism enables reducing the total number of additions and applies the modern parallelization technologies effectively.
