【Abstract】 Through the analysis about RSA algorithm and comparison with several realization methods,aiming to the problem of huge calculation,a series of methods are adopted in order to create the secret key couple.It includes test through small prime numbers aggregate,optimized Miner Rabit test,solution to the biggest common divisor by Stein algorithm and arithmetical compliment equation.After the discussion,a higher speed realization method is presented.In the test environment of AMD266 CPU,64MB memory and Windows98 OS,the encryption intensity,the method length of RSA algorithm, is selected to be 1 024 bit.The average running time to extract the secret key couple of RSA algorithm is 3 622 seconds by 100 times and satisfies the need of practicalities.更多还原
