中文摘要: 智能手机已成为便携、隐蔽的数据载体,虽然数据机密性可以通过加密技术获得有效的保护,但某些时候用户可能在胁迫下暴露密钥。为了将需要隐藏的敏感数据隐式存储在智能手机中,本课题通过在智能手机的空闲存储空间加入隐藏分区,将PDE存储引入到Android系统,研制支持PDE存储的安全增强型Android系统,同时利用桌面环境下的否认加密技术经验,设计新的对策以应对移动系统中的具体威胁源,确保智能手机上PDE存储的可否认性。

英文摘要: Smart phone has become a portable and hidden data carrier. Although data confidentiality can be effectively preserved through encryption, this is inadequate, as users may be coerced into disclosing their decryption keys in certain situations. In order to conceal the sensitive data which needs to be hidden in the smart phone, we will develop a security-enhanced android system supporting plausibly deniable encryption storage by building a hidden volume in a mobile devices free storage space. Further, we will also design novel countermeasures for threats specific to mobile system with lessons learned deniable encryption in the desktop environment. These new techniques can guarantee the deniable of PDE storage in the smart phone.
