**课程名称：PKI - 证书基础设施** **课程概述：** 本课程深入探讨了公钥基础设施 (PKI) 的基础知识，以及它在保护数字应用程序、交易、身份和供应链方面的重要作用。学完本课程后，您将全面掌握 PKI 的工作原理、组成部分及其应用。 PKI 是一个利用数字证书来认证用户、设备和服务的系统。它通过非对称加密技术，为数据加密和签名创建安全连接。 **PKI 工作原理：** 1. **证书请求：** 组织向证书颁发机构 (CA) 申请数字证书。 2. **身份验证：** 注册机构 (RA) 负责验证组织或用户的身份。 3. **证书颁发：** CA 使用其私钥对数字证书进行签名并颁发。 4. **公钥发布：** CA 发布其公钥，该公钥可用于加密数据或验证数字签名。 5. **数据传输：** 使用公钥加密数据，然后使用私钥进行解密。 **PKI 组成部分：** * **证书颁发机构 (CA)：** 作为可信的第三方，负责颁发、存储和签名数字证书，并维护证书吊销列表 (CRL)。 * **注册机构 (RA)：** 负责验证申请数字证书的用户或设备的身份。 * **数字证书：** 一种电子凭证，用于认证用户、设备或服务的身份。 * **证书生命周期管理 (CLM)：** 管理数字证书的整个生命周期，包括颁发、续订和吊销。 **应用领域：** PKI 广泛应用于保护数字应用程序、交易、身份和供应链。
In this course, we will explore the fundamentals of Public Key Infrastructure (PKI) and its role in securing digital applications, transactions, identities, and supply chains. By the end of this course, you will have a comprehensive understanding of how PKI works, its components, and its applications.Public Key Infrastructure (PKI) is a system that uses digital certificates to authenticate users, devices, and services. PKI uses asymmetric encryption to create a secure connection for data encryption and signing.How PKI worksAn organization requests a digital certificate from a Certificate Authority (CA).The Registration Authority (RA) verifies the identity of the organization or user.The CA issues the digital certificate, which is signed with the CA's private key.The CA publishes the public key, which can be used to encrypt or verify a digital signature.The public key is used to encrypt data, which is then decrypted with the private key.Components of PKICertificate Authority (CA)A trusted third-party that issues, stores, and signs digital certificates. CAs also maintain a Certificate Revocation List (CRL).Registration Authority (RA)Verifies the identity of the user or device requesting a digital certificate.Digital CertificateAn electronic credential that authenticates the identity of a user, device, or service.Certificate Lifecycle Management (CLM)Manages the lifecycle of digital certificates, including issuing, renewing, and revoking them.PKI is used to secure digital applications, transactions, identities, and supply chains.
