摘要
用软件实现RSA密码系统的最大缺点是加解密的速度低。在RSA中,最基本的运算是Xy(modz),其中,x,y和z是高达100~200位的十进制数,如果采用查表技术代替上述的计算,可大大提高加密和解密的速度。
The most undesirable effect of the RSA cryptosystem implemented by software is its low speed in procedure of encryption or decryption. In the RSA cryptosystem, the basic calculation is xy(mod z),in which x,y and z can be numbers of about 100~200 digits. This paper is aimed at greatly improving the efficiency of encryption or decryption by the look-up tables.
