Design of end-to-end Encryption Systems in the Digital Era

On the Internet, data transmission is the most basic service, and many institutions use data transmission that contains confidential or sensitive information. Due to the insecurity of the network itself, it is prone to eavesdropping, malicious tampering, and malicious attacks. How to ensure the security of information has become a key issue in communication security. This article aimed to address the above issues and explore the design and application of end-to-end encryption systems in the digital era. This article first provided a detailed explanation of encryption technologies related to key management technology, then discussed how to build an end-to-end encryption system, and finally conducts an experimental analysis of end-to-end voice encryption. When it came to data latency, the delay time for encrypting and decrypting data in this scheme was 5.lms and 4.13ms, which was the smallest, indicating that the system data transmission in this scheme was the smoothest.
