摘要
针对当前对Flash存储器中敏感数据的安全存储需求,设计实现了一种Flash安全存储控制器。通过数据加密技术和访问地址加扰技术保证存储数据的安全,并建立了一种分区访问控制机制,实现了不同等级用户的访问控制。对该存储控制器设计进行验证和分析,结果表明,设计的Flash安全存储控制器在保证Flash访问速率的基础上,实现了对Flash存储器的硬件级安全防护和分区访问控制,方法不仅可行,而且具有较强的实用性。
To protect the security of sensitive data stored in Flash memory,a Flash safe storage controller is designed and implemented.Data encryption technology and access address scrambling technology are used to ensure the safety of stored data,and a partition access control mechanism is established to achieve access control for users of different levels.The storage controller design is verified and analyzed.The experiment results indicate that the designed Flash safe storage controller realizes the hardware-level security protection and partition access control of the Flash memory on the basis of ensuring the Flash access rate.This method is not only feasible,but also has fairly strong practicability.
