Analysis of SSL Security Advantages Based on National Cryptography

With the rapid development of information technology, network security has become the focus of social attention. Once a large amount of data transmitted in the network is leaked, it will cause trouble to people at best. If it involves property information, personal privacy or important business information, it will not only damage personal reputation, but also may cause huge losses to the company. Therefore, it is very necessary to encrypt and protect network transmission data. This article focuses on network transmission data encryption technology, and systematically analyzes the characteristics of data encryption, digital signature verification, and the establishment of encrypted channel transmission. Taking SSL encryption technology as the research object, the two mainstream solutions of national secret SSL and commercial secret SSL are compared in key efficiency and performance, autonomous controllability, and certificate chain trust system. The working principle and data encryption and decryption process of national secret SSL are mainly explained, and the advantages and applicable scenarios of national secret SSL are explained in combination with actual application scenarios, providing a reference for encryption technology selection for the actual needs of different security industries, aiming to provide a way of thinking for building a data transmission protection system that takes both security and feasibility.
