Computer Network Security Strategy Based on Data Encryption Technology

In today's information society, the security problems of computer networks are increasingly prominent, and security threats such as Data breach and hacker attacks are emerging. Data encryption technology, as an effective security measure, is used in computer network security. It can protect the confidentiality, integrity, and availability of data, and reduce security risks. This article adopted the method of literature review, and summarized the research progress and application status of computer network security strategies based on data encryption technology by sorting and analyzing relevant research literature from various countries. It also explored the role and advantages of data encryption technology in network security, as well as its shortcomings and development direction. The research conclusion showed that after installing the TLS/SSL protocol, the number of email integrity breaches decreased from 378 to 73, and the number of email confidentiality breaches increased from 318 to 81. This indicated that data encryption technology can effectively protect our data security. It has broad application prospects, which can improve network security performance. However, data encryption technology itself also has some limitations and shortcomings, such as the complexity and speed of encryption algorithms, which require further exploration and improvement. Therefore, in the future, it is necessary to strengthen the research and application of data encryption technology, and continuously improve its security.
