Product Overview

The “SSL Certificate Service” newly launched by UCloud Global cooperates with several authoritative certificate authorities such as AsiaTrust and Shanghai CA, providing cloud users with a one-stop service for SSL certificate purchase, certification, issuance, deployment, and management.

SSL Technical Principles

SSL refers to the Secure Sockets Layer protocol (and the Transport Layer Protocol TLS), which is located between the TCP/IP protocol and various application layer protocols, providing security support for data communication, and it is the most widely used security protocol. It provides a secure information channel between two machines operating on the Internet or internal network connections, namely HTTPS.

The Importance of SSL Certificates

At the beginning of the Internet development, the HTTP protocol was invented and widely used, but the founder Ted Nelson did not consider the issue of information transmission security, which buried a “mine” for the future Internet information security. The HTTP protocol is transmitted in plaintext, and cannot guarantee the security during the data transmission process, leading to data leakage, data tampering, traffic hijacking, phishing attacks and other security problems occurring frequently. To solve this security problem, the HTTPS protocol was produced, which double guarantees data security through data encryption transmission and identity verification, so that data is not leaked or tampered with during the transmission process. Therefore, SSL certificates in cloud services are necessary products to ensure information transmission security.

After installing the SSL certificate, during the user’s visit to the website, the owner of the certificate’s identity information is recognized to confirm the authenticity of the website, thereby ensuring that the site identifies phishing websites. During data transmission, a secure information transmission encryption channel can be established to ensure the confidentiality of information transmission. Protect user account security, prevent information leakage and prevent information tampering. Effectively solve the trouble of man-in-the-middle hijacking, eliminate the problem of altering search result pages, force pop-up or embedded ads, prevent the loss of promotion traffic, and greatly reduce the cost of promotion.
