保护用户隐私的数据加密与安全存储方案

文中提出了一套保护用户隐私的数据加密与安全存储方案，选择了适合的加密算法和密钥管理方案。通过对比分析不同加密算法的安全性和效率，最终选择了AES 256，RSA等加密算法，并设计了三级密钥管理方案，实现了对密钥的安全存储和分发。在数据存储方面，以eMMC存储器为存储介质，实现了基于角色和权限的访问控制机制，确保用户只能访问其被授权的数据。

Design of Data Encryption and Secure Storage Solutions to Protect User Privacy

In this paper, a data encryption and secure storage scheme to protect user privacy is proposed, and suitable encryption algorithms and key management schemes are selected. By comparing and analyzing the security and efficiency of different encryption algorithms, AES-256, RSA and other encryption algorithms are finally selected, and three-level key management schemes are designed to realize the secure storage and distribution of keys. In terms of data storage, eMMC memory is selected as the storage medium, and an access control mechanism based on roles and permissions is implemented to ensure that users can only access their authorized data.
