Recently,Harn proposed one digital signature scheme for DiffieHellman key exchange system,but its security is lower. In this paper, firstly,the security of Harn's scheme is ananlysed and one weakness in the Harn system is pointed out.Then, two modified schemes to avoid this weakness are proposed by us.
