Abstract
With the rapid development of information technology, data privacy protection has become a key issue in the field of information security. As the core carrier of data storage, the security of the database is very important. This paper focuses on database encryption technology and data privacy protection, and aims to discuss how to achieve efficient security protection under the premise of ensuring data availability. Based on the comprehensive analysis of the existing database encryption technology, including symmetric encryption, asymmetric encryption and homomorphic encryption, a multi-layer encryption mechanism and access control strategy is proposed. This solution not only solves the problem of inefficiency of ciphertext operation in the traditional encryption mode, but also improves the overall security of the system by introducing fine-grained access control. The experimental results show that the proposed encryption algorithm can effectively reduce the computing overhead and improve the query response speed while ensuring the data security. In addition, according to the data sharing requirements in the cloud environment, a privacy protection fr amework based on attribute-based encryption is designed, which realizes the accurate authorization management of data use by the data owner.
