摘 要: 提出了许多称作有向签名的新方案,即只有特定的收方才能验证签名的正确性。在ElGamal型签名方案和相应的具有报文还原功能的签名方案(称作MR型签名方案)上构造了5个有向签名方案。其中MR型有向签名方案不但可以用于数字签名,而且可以用于数据加密。 This paper presents many schemes called directed signature schemes,only specific receiver can authenticate the truth of signature.Five directed signature schemes are proposed based on both ElGamal type signature schemes and corresponding signature schemes which giving message recovery (called MR type signature schemes).In these schemes,MR type directed signature schemes are a new kind of mixed schemes for encryption and signature.
