由于数字签名方案无法保证谁是经签名的消息的目标接收方，那么也就没有人能确定恶意方声明的真实性。
Because the digital signature scheme guarantees nothing about who is the intended recipient of the signed message, nobody can determine whether the malicious party's claim is true or not.
由于数字签名方案无法保证消息被发送方签名并发送的次数，那么也就没有人能确定恶意接收方声明的真实性。
Because the digital signature scheme guarantees nothing about how many times the message was signed and sent by the sender, nobody can determine whether the malicious recipient's claim is true or not.
每个发布的U - Prove令牌都包含了发布方关于所有内容的不可伪造的数字签名，这是通过使用它的私钥由发布方创建的。
Each issued U-Prove token contains an unforgeable digital signature of its Issuer on the entire contents, created by the Issuer by applying its private key.
数字签名用于验证消息是否真正由发送方发送；数字签名结合了消息摘要和公钥密码术的使用。
Digital signatures are used to verify that the message was actually sent by the sender; they combine the use of message digests and public key cryptography.
因为仅仅有数字签名并无法保证发送方就是他们自己所声称的人，消息的传输很容易遭受恶意第三方诸如再现攻击等技术的袭击。
Because a signature alone does not guarantee that the sender is who they say they are, the message transmission is vulnerable to techniques such as replay attacks by some malicious third party.
接收方使用发送方的对应公钥验证数字签名。
The receiver uses the sender's corresponding public key to verify the digital signature.
类似地，数字签名则是消息发送方使用自己的私钥签署消息。
Similarly, with a digital signature the sender of the message signs the message using his or her own private key.
一个常用的实践方法是使用发送方的X . 509证书的私钥对Web服务请求的SOAPBody进行数字签名。
A common practice is to use the private key of the sender's X.509 certificate to digitally sign the SOAP body of a web service request.
公钥证书上的数字签名可以验证该公钥的可靠性以及持有它的那一方的可靠性。
The digital signature on a public key certificate can validate the authenticity of the public key and therefore the party who holds it.
该系统借助可信第三方技术、数字签名和加密等技术，确保电子交易的安全性和可靠性。
By use of the TTP, digital signature, encryption and decryption technologies, the system guaranteed the security and reliability of thee-business trade.
该方案是可证实数字签名的改进，但比证实签名简单且不需要第三方的参与。
The schemes are the improvement of confirm signature, and is much simpler in practice and of significant feature that it does not need the third party to take part in the scheme.
使代码能够要求其调用方拥有数字签名，从而只允许特定组织或特定站点的调用方来调用受保护的代码。
Enables code to demand that its callers possess a digital signature, thus allowing only callers from a particular organization or site to call the protected code.
一个被信任的第三方组织或公司，由他们来负责发放用来创建数字签名和生成公钥私钥对的数字证书。
A trusted third-party organisation or company that issues digital certificates used to create digital signatures and public-private key pairs.
一个被信任的第三方组织或公司，由他们来负责发放用来创建数字签名和生成公钥私钥对的数字证书。
A trusted third-party organisation or company that issues digital certificates used to create digital signatures and public-private key pairs.
