Abstract
With the rapid development of information technology, data security has become a critical research area. As key methods for ensuring data security, the performance evaluation and optimization of database encryption and decryption technologies hold profound significance. This study aims to thoroughly investigate the performance characteristics of database encryption and decryption techniques and propose effective optimization strategies. Based on current mainstream symmetric and asymmetric encryption algorithms, a comprehensive performance evaluation system was constructed, encompassing multiple dimensions such as encryption and decryption speed, resource utilization rate, and data integrity. Testing was conducted using a combination of simulation experiments and real-world application environments. The results indicate that the performance of various encryption algorithms varies significantly across different scenarios. Symmetric encryption algorithms exhibit advantages in speed but have relatively lower security levels; conversely, while asymmetric encryption algorithms offer higher security, they are slower and consume more resources. Innovatively, this study proposes a hybrid encryption mechanism that integrates symmetric and asymmetric encryption organically, thereby effectively enhancing encryption and decryption speeds and reducing resource utilization rates while ensuring data security. Additionally, improvements were made to key factors affecting performance in existing technologies, such as key management and algorithmic complexity, further improving the overall performance of database encryption and decryption technologies. This research provides theoretical foundations and technical support for the application of database encryption and decryption technologies and holds significant value for advancing the field of data security.
