摘 要: 在公钥密码应用中,RSA算法现在仍处于主流地位。RSA算法在受限环境、嵌入式环境中最慢的操作是生成密钥对,即寻找两个大素数。该文在Robin-Miller概率素性判别算法之前,采用适合于嵌入环境实现的方法,先对随机数进行过滤,可以使素数生成的整体效率提高50%。 RSA is the mostly wide-spread public key algorithm today. To generate big primes is the slowest operation for RSA in restricted enviroments such as smart card. The article puts forward a method to sieve out mass composite numbers before performing Robin-Miller primitive check. The overall performance of generating key pair for RSA can be improved about 50% by this method.
