Investigating Data Encryption Technology's Use to Improve Security for Computer Network Communication
Chaorong Song · 2023
With the rapid development of information technology, computer network communication plays a crucial role in modern society. However, with the wide application of network communications, network security issues have become increasingly prominent. Risks such as information leakage and illegal access during data transmission pose a serious threat to the security of individuals, organisations and the state. Data encryption technology, as a key security safeguard, is widely used in network communications to protect the confidentiality and integrity of data. This study aims to explore the application of data encryption technology in computer network communication security. Through literature review and practical case analysis, we have discussed in depth the principle, classification and common algorithms of data encryption. Meanwhile, we explored the role of data encryption technology in network communication, including encryption of data transmission, authentication assurance and security key management. In addition, we also focus on the challenges facing data encryption techniques, such as performance loss and the rise of quantum computing. Finally, we emphasise the importance of strengthening the research and practice of data encryption technologies to address evolving cybersecurity threats. Taken together, data encryption technology plays an important role in securing computer network communications and provides strong support for building a secure and reliable network environment.
