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. This provides a security proof for a variant of the signature standards ISO 9796-2 and PKCS#1 v1.5, in which a larger digest size is used. Keywords.... (Update)
