Abstract

With the rapid development of information technology, the problem of computer network security has become increasingly prominent. As an important technical means to ensure network security, the research and application of data encryption algorithm has been widely concerned. The purpose of this paper is to deeply discuss the computer network security technology based on data encryption algorithm, analyze its current situation, existing problems and optimization countermeasures. Firstly, this paper summarizes the theoretical basis of data encryption algorithm, including symmetric encryption algorithm and asymmetric encryption algorithm, and introduces the evaluation index of encryption algorithm. Then, this paper analyzes the application scenarios of data encryption algorithm in computer network security, and the impact of encryption algorithm on network security. At the same time, this paper also points out the security problems, key management problems, adaptability challenges and the influence of regulations and policies in the implementation of the existing encryption algorithms. To solve these problems, this paper proposes a series of optimization countermeasures, including strengthening the research and development and innovation of encryption algorithms, optimizing the key management mechanism, building a multi-level defense system, and coping with legal and policy challenges. These measures aim to improve the security and adaptability of data encryption algorithms and provide more reliable security for computer networks. This research not only enriches the theoretical system of data encryption algorithm, but also provides useful guidance and reference for practice. In the future, with the continuous development and changes of the computer network environment, it is necessary to continue to pay attention to and solve the emerging security problems in order to promote the continuous progress of data encryption algorithm technology and the continuous development of network security.
