The paper proposes an analysis of the security of the Domingo-Ferrer's homomorphic encryption scheme against the ciphertext-only attack. This cryptosystem provides a good counterexample to the equivalence hypothesis of ciphertext-only attack and known plaintext attack on encryption schemes, that are homomorphic over the residue ring modulo a hardly-factorizable number.
Keywords: homomorphic encryption, ciphertext-only attack, Domingo-Ferrer's encryption scheme, factorization problem.
