摘要
求两个整数的最大公因子(gcd)是密码学中重要的算法.左移gcd算法是对右移gcd算法在执行效率方面的改进.提出了一个改进的左移2进制gcd算法.分析和实验均表明,改进算法比原算法具有更高的效率.
Finding the greatest common divisor (gcd) of two integers is an important algorithm in cryptography. The gcd algorithm with left shifts is an improvement for the one with right shifts in executive efficiency. An improvement of the binary gcd algorithm with left shifts was proposed. The analysis and experiment show the improved algorithm has more efficiency than the old one.
