Data Encryption Technology in Network Information Security

Abstract

Data encryption is the process of converting data from a readable format to a jumbled piece of information. This is carried out in order to prevent snoopers from viewing private data in transit. It is possible to encrypt every kind of network communication, including documents, files, communications, and messages themselves. It is impossible to overstate the value of encryption as a tool for protecting the integrity of our data. On the internet, almost all of the websites and programs we use employ some kind of encryption. This work fully exploits the public key cryptosystem's ease of key management and the symmetric key cryptographic algorithm's quick speed. The most cutting-edge data encryption methods, particularly the RSA algorithms, are suggested in this work. The data encryption system technology program is designed, and the application program is in the Windows operating system. The system provides a feasible mode of operation for the quick and secure transfer of sensitive data by fully integrating the symmetric key encryption technique and the public key encryption algorithm. It also lay the groundwork for creating a solid and comprehensive computer network security system.
