能帮我翻译一下，下面的英语吗？这是我的大学专业作业，最好不要用软件翻译

Digital certificates combined with public key encryption provide further protection of electronic transactions by authenticating a user’s identify.
Digital certificates are data fields used to establish the identity of the sender and to provide the receiver with the means to encode a reply.
They use a trusted third party known as a certificate authority to validate a user’s identity.
Both digital signatures and digital certificates play a role in authentication.
Authentication refers to the ability of each party to know that the other parties are who they claim to be.

Answer 1

数字证书结合公共字符的加密方式为电子交易通过验证用户真实身份的方式提供了更进一步的保护。 数字证书属于数据域，被用于建立发送方的身份，并提供给接收方加密某个应答的方方法。它们使用一个可信的第三方（通常称作证书授权）来确认一个用户的身份。
数字签名和数字证书在验证过程中都扮演着一个不同的角色。 验证是指各方都知道自称的其他方的真实身份的一种能力。
