汉英对照:
Chinese-English Translation:

CA登录就是CA安全认证登录,CA包括数字证书,用户下载得到的证书也叫私钥,CA证书就是证明网站安全身份的证明,是网站自动加载的,也叫公钥。 CA属于国际电信联盟推荐标准方案。

CA login is ca security authentication login. CA includes digital certificate. The certificate downloaded by users is also called private key. CA certificate is the proof of website security identity. It is automatically loaded by website, also called public key. CA belongs to the recommended standard scheme of ITU.

CA 就是 CA 安全认证的意思,是计算机网络的知识。CA 包括数字证书—用户下载得到的证书也叫私钥,CA 证书就是证明网站安全身份的证明,是网站自动加载的,也叫公钥。 CA 属于国际电信联盟推荐标准方案。

CA is the meaning of Ca security authentication, which is the knowledge of computer network. CA includes digital certificate – the certificate downloaded by users is also called private key. CA certificate is the proof of website security identity, which is automatically loaded by website, also called public key. CA belongs to the recommended standard scheme of ITU.

使用 CA(数字证书)登陆的方式有什么好处

What are the advantages of using Ca (digital certificate) to log in

它是由一个由权威机构—–CA 机构,又称为证书授权(Certificate Authority)中心发行的,人们可以在网上用它来识别对方的身份。数字证书是一个经证书授权中心数字签名的包含公开密钥拥有者信息以及公开密钥的文件。最简单的证书包含一个公开密钥、名称以及证书授权中心的数字签名。我们推荐大家使用数字证书登陆网上办税系统的原因,主要是根据《中华人民共和国电子签名法》规定,使用数字证书是对您身份的一种认证,也是税企双方在法律上的一个共同约定,对征纳双方的权利义务都是一种相互的保证。同时,我们对采取 CA 数字证书登录方式的纳税人提供了免于定期报送相关纸质资料的便捷服务。

It is issued by an authoritative organization – Ca organization, also known as certificate authority center. People can use it to identify each other online. A digital certificate is a file that is digitally signed by the certificate authority center and contains the information of the public key owner and the public key. The simplest certificate contains a public key, name, and digital signature of the certificate authority. The reason why we recommend you to use digital certificate to log on to the online tax system is mainly that according to the provisions of the law of the people’s Republic of China on electronic signature, using digital certificate is a kind of authentication for your identity, a common agreement in law between tax enterprises, and a mutual guarantee for the rights and obligations of both tax collectors and payers. At the same time, we provide a convenient service for taxpayers who adopt the CA digital certificate login mode to avoid submitting relevant paper materials on a regular basis.

CA 证书是什么意思

What does CA certificate mean

CA 也拥有一个证书(内含公钥和私钥)。网上的公众用户通过验证 CA 的签字从而信任 CA ,任何人都可以得到 CA 的证书(含公钥),用以验证它所签发的证书。

The CA also has a certificate that contains the public and private keys. Public users on the Internet trust Ca by verifying CA’s signature. Anyone can get CA’s certificate (including public key) to verify the certificate it issues.

如果用户想得到一份属于自己的证书,他应先向 CA 提出申请。在 CA 判明申请者的身份后,便为他分配一个公钥,并且 CA 将该公钥与申请者的身份信息绑在一起,并为之签字后,便形成证书发给申请者。

If the user wants to get a certificate of his own, he should first apply to the ca. After the CA determines the identity of the applicant, it assigns him a public key, and the CA binds the public key with the identity information of the applicant, and signs for it, and then forms a certificate and sends it to the applicant.

如果一个用户想鉴别另一个证书的真伪,他就用 CA 的公钥对那个证书上的签字进行验证,一旦验证通过,该证书就被认为是有效的。证书实际是由证书签证机关(CA)签发的对用户的公钥的认证。

If a user wants to verify the authenticity of another certificate, he uses the CA’s public key to verify the signature on that certificate. Once the verification is passed, the certificate is considered valid. A certificate is actually a public key authentication issued by a certification authority (CA).

证书的内容包括:电子签证机关的信息、公钥用户信息、公钥、权威机构的签字和有效期等等。目前,证书的格式和验证方法普遍遵循 X.509 国际标准。

The contents of the certificate include: information of the electronic visa authority, public key user information, public key, signature and validity of the authority, etc. At present, the format and verification method of certificate generally follow the international standard X.509.

加密

encryption

我们将文字转换成不能直接阅读的形式(即密文)的过程称为加密。即把我们平时看到的“http”加密成“https”来传输,这样保证了信息在传输的过程中不被窃听。

The process of transforming text into a form that cannot be read directly (i.e., ciphertext) is called encryption. That is, we usually see “HTTP” encrypted into “HTTPS” to transmit, so as to ensure that the information in the process of transmission is not eavesdropped.

解密

decrypt

我们将密文转换成能够直接阅读的文字(即明文)的过程称为解密。

The process of converting ciphertext into plain text that can be read directly is called decryption.

如何在电子文档上实现签名的目的呢?我们可以使用数字签名。RSA 公钥体制可实现对数字信息的数字签名,

How to achieve the purpose of signature on electronic documents? We can use digital signature. RSA public key system can realize digital signature of digital information,

方法

method

信息发送者用其私钥对从所传报文中提取出的特征数据(或称数字指纹)进行 RSA 算法操作,以保证发信人无法抵赖曾发过该信息(即不可抵赖性),同时也确保信息报文在传递过程中未被篡改(即完整性)。当信息接收者收到报文后,就可以用发送者的公钥对数字签名进行验证。

The information sender uses its private key to perform RSA algorithm operation on the characteristic data (or digital fingerprint) extracted from the transmitted message, so as to ensure that the sender can not deny that the information has been sent (i.e. non repudiation), but also ensure that the information message is not tampered (i.e. integrity) in the transmission process. When the receiver receives the message, he can verify the digital signature with the sender’s public key.

在数字签名中有重要作用的数字指纹是通过一类特殊的散列函数(HASH 函数) 生成的。

The digital fingerprint, which plays an important role in digital signature, is generated by a special hash function (hash function).
