本文介绍了公开密码加密体制、单向散列函数、认证机构和公钥管理等。并在此基础上，详细探讨了明文不需要保密的一般数字签名实现算法、明文需要保密的数字签名实现算法；提出了发送方和接收方均不可抵赖的带加密数字签名实现算法。这些算法具有安全、快捷等特点，适合于不同应用场合的网络数据通信。

Abstract: Public key system, single direction Hash function, certificate authority organization and public key management are introduced. On this base, general digital signature which document does not need to be kept secrecy, and encrypting digital signature which document needs to be kept secrecy are discussed. Undeniable encrypting digital signature is presented. These signature technologies have the advantages of safety and speediness，they are suitable for internet data communication in different areas.
