Abstract: This article aims to study and compare two commonly used data encryption algorithms: symmetric encryption and asymmetric encryption. The article first introduces the basic concept and purpose of data encryption, as well as the principles of symmetric and asymmetric encryption. Next, the article elaborates in detail on the principles and implementation methods of two symmetric encryption algorithms, DES and AES, as well as RSA and ECC, as well as their performance evaluation and comparison. Through the research and implementation of these algorithms, we can better understand the principles and applications of data encryption, providing effective means for data security protection. Meanwhile, by evaluating and comparing the performance of these algorithms, we can choose the most suitable encryption algorithm based on different needs to achieve better encryption results. This article has certain reference value for the research and application of data encryption algorithms, and has certain guiding significance for data security protection.
