摘要
为了解决固态盘的存储安全问题,研究了可信存储技术,并将其应用于固态盘的安全保护设计中。提出了一种基于固件程序的安全保护方法,利用ATA协议可信计算和安全命令集下的安全命令,在固件设计中定义了专用的安全命令处理流程,实现了固态盘与主机的双向认证和对固态盘存储区的访问控制两种安全功能,增强了固态盘的安全性,有效地限制了对固态盘的随意访问。
To solve the security problem in solid-state disk（SSD）, by researching and introducing trusted storage technology into SSD design, a protecting method based on firmware is proposed.Using security command defined in ATA trusted computing feature set and security feature set, customized ATA commands handling program is designed to implement the dual authentication process and access control during firmware designing.By this protecting method, security in SSD was enhanced and illegal access to SSD is restricted effectively.
