Abstract: Two new digital signature schemes whose security are based on both discrete logarithms and factorization are proposed.The paper also considers some possible attacks to the schemes,shows that the two schemes are more secure than the ElGamal's signature scheme and the Rabin's signature scheme.

Key words: factorization, discrete logarithm, digtal signature
