* It gives the paper a lot more charity than it would ordinarily receive*. - Critically: Schnorr has not empirically demonstrated a break in RSA.

- No, in the paper he discusses the case when there are many relatively small primes in the factorization of the number. These primes are less than 10^9. That is around 2^30. In the case of RSA there is a product of two big prime numbers. Since 2002 recommended parameters for the key size are 1024 bit. So prime factors are around 2^500

Schnorr/DSA blind signatures. The DSA scheme is based (not loosely) on the Elgamal and Schnorr signature schemes. Let (g, p, q, y) be the public key, where (g, p, q) describe a group of order q, with generator g (see here for details on how these elements are chosen) and y = g^x mod p.Let H() be a hash function that maps to elements in the space (1, 2, , q-1) This paper provides such a proof for GQ based on the assumed security of RSA under one more inversion, an extension of the usual one-wayness assumption that was introduced in [5]. It also provides such a proof for the Schnorr scheme based on a corresponding discrete-log related assumption
