摘 要: 本文提出了一个基于RSA的 (t0 ,t1 ,t,n)门限签名方案。与已有的 (t0 ,t,n)门限签名相比 ,该方案具备以下优点 :( 1 )基于广泛认可的RSA方案 ;( 2 )公钥及签名验证和普通RSA门限签名相同 ;( 3 ) This paper proposes a (t_0,t_1,t,n)-threshold signature scheme based on RSA. Compared with the existing (t_0,t,n)-threshold signatures, the scheme has the advantages as follows: (1) The scheme is based on the widely approved RSA signature scheme; (2) The public key and the verification of the signature are similar to those of the general RSA signatures; (3) Its security and efficiency have been improved.
