provides public-key cryptography and digital signature services to manage keys and certificates. An organization can establish a secure network environment by using the PKI framework to manage keys and certificates. PKI mainly consists of four parts: Certificates in the form of X-V3 and certificate revocation List CRL (V2), CA operation Protocol, CA Management Protocol, CA policy development. A typical, co

Key words: Ssl,pki,macAbstract: SSL leverages data encryption, authentication, and message integrity validation mechanisms to provide security assurances for application-layer protocols based on reliable connections such as TCP. This paper introduces the background, security mechanism, working process and typical networking application of SSL.Abbreviations: Abbreviations English full Name Chinese explanation

Objective The CA is the issuing authority for the certificate, which is the core of the PKI.
