Abstract
With the rapid development of information technology, LAN communication security is facing many challenges, and data encryption algorithm has become the key technology to ensure information security. This study aims to evaluate the performance of different data encryption algorithms in protecting LAN communication security and provide theoretical basis and technical support for practical applications. Through the in-depth analysis of symmetric encryption algorithm (such as AES, DES) and asymmetric encryption algorithm (such as RSA, ECC), and using the method of combining simulated attack experiment and performance test, a test platform containing a variety of network environment and load conditions is built. The results show that under the same conditions, AES algorithm has higher encryption strength and faster processing speed than DES; ECC algorithm requires shorter key length and consumes less resources. The innovation is to integrate multiple typical attack scenarios into the performance evaluation system for the first time, and introduce a comprehensive evaluation model to comprehensively consider the security and efficiency of each algorithm.
