数字签名(Digital Signature)是使用特定的加密算法为电子文档或消息创建的一种加密摘要,用于验证消息的完整性以及消息来源的身份。 1. 生成过程: 发送者首先使用某种哈希函数为原始消息生成一个摘要。 然后,使用发送者的私钥加密这个摘要,得到的加密结果即为数字签名。 发送者将原始消息和数字签名一起发送给接收者...
A digital signature is a type of electronic signature. It's used as acybersecuritymeasure to encrypt a document to ensure its authenticity. According to theCybersecurity and Infrastructure Security Agency(CISA), “Digital signatures create a virtual fingerprint that is unique to a person or entity...
A person creates a digital signature using a private key to encrypt a signature. At the same time, hash data is created and encrypted. The recipient uses a signer's public key to decrypt the signature. A digital signature can be used with any kind of message, whether or not it's encryp...

正确答案:A 解析:A正确。数字签名是使用发送者的私钥加密了的散列值。数字签名的行为就是用私钥对消息的散列值进行加密。如果Sam想确保他发送给Debbie的消息不被修改,并且希望Debbie相信这个消息只是来自于他自己,那么他就可以对这个消息进行数字签名。这就意味着对该消息先进行单向散列函数算法,然后Sam用他的私钥对这...
