Abstract

We present a protocol for convincing an opponent that an integer N is of the form PrQs, with P and Q primes congruent to 3 modulo 4 and with r and s odd. Our protocol is provably secure in the sense that it does not reveal the factors of N. The protocol is very fast and therefore can be used in practice.
