计数RSA整数

Counting RSA-integers

Andreas Decker, Pieter Moree

摘要:

在RSA密码系统中,n = p. q形式的整数(其中p和q是大小相当的素数)("RSA整数")起着重要的作用。密码学家的一个民间传说结果是,对于固定的r> 1,C_r(x),即整数n <= x的个数,其形式为n = pq,p和q是素数,使得p <q <rp,对于某个常数c_r> 0,渐近等于c_r * x * log ^{-2} x。这里我们证明了这一点,并证明了c_r = 2logr。

英文摘要:

In the RSA cryptosystem integers of the form n=p.q with p and q primes of comparable size (`RSA-integers') play an important role. It is a folklore result of cryptographers that C_r(x), the number of integers n<=x that are of the form n=pq with p and q primes such that p<q<rp, is for fixed r>1 asymptotically equal to c_r*x*log^{-2}x for some constant c_r>0. Here we prove this and show that c_r=2log r.
