Abstract
We study the security of partial-domain hash signature schemes, in which the output size of the hash function is only a fraction of the modulus size. We show that for e = 2 (Rabin), partial-domain hash signature schemes are provably secure in the random oracle model, if the output size of the hash function is larger than 2=3 of the modulus size.
