[Here the variable a is chosen randomly from the uniform distribution on {0,1,...,q-1} and b is distributed uniformly over its range, but they are kept secret from the attacker.] Don Coppersmith mentioned in his email that he can factor n if b = O(n^{1/6}).
This means there is a ciphertext-only attack on David Colston's QPK scheme requiring 5 ciphertexts...
[Yes, I know Don Coppersmith already demolished the QPK scheme by finding the message from only one known ciphertext, but maybe my post will be of independent interest.] Let me state one result from Lagarias, Crypto '83.

In 1996, Don Coppersmith proposed a method for finding small solutions of polynomial equations.
With the help of Coppersmith's method, one can construct polynomial time algorithms that find the entire key using only a fraction of the secret key bits, provided that the public key e is not too large.
Using Coppersmith's method, one can extend this attack to secret keys of the form d= d1/d2 modulo phi(N) with small d1 and d2.
