This paper proposes a kind of ElGamal-type sequential multi-digital signature scheme,this scheme allows many people to conduct sequential signature for the same file but the signature length and the time for verifying the signature do not increase with the increase of the number of signature people,furthermore,in the whole process of signature and signature verification,the time-consuming reverse operation is shunned,as a result,this scheme improves operation efficiency and has strong practicability.
