摘　　要：随着越来越多的重要数据存储在磁盘上,磁盘数据的安全保护逐渐成为备受关注的问题。众多的安全威胁如磁盘数据被非法修改、磁盘数据泄漏、磁盘失窃,都可能会对保存着重要信息的组织如军队、政府、企业等造成无法估计的损失。以保密性、完整性、可用性、验证和授权为安全威胁模型,从硬件和软件两个方面对当前主要的磁盘数据安全保护技术、系统进行分析和比较,并展望今后的研究方向。With more and more important data are stored on hard disk, the protection of these data has become a hot issue. Various security threats such as malicious data modification, data leak, hard disk stolen and etc. Will bring inestimable loss to the organizations that hold these critical data such as army, government and enterprises. Analyzed and compared several important hard disk data protection techniques and systems based on the threat model confidentiality, integrity, availability, authentication and authorization（CIAAA）. Discussed potential research issues.
