CaSE: Cache-Assisted Secure Execution on ARM Processors

Ning Zhang, Kun Sun, Wenjing Lou, Y. Thomas Hou
2016 2016 IEEE Symposium on Security and Privacy (SP)  
CaSE utilizes TrustZone and Cache-as-RAM technique to create a cache-based isolated execution environment, which can protect both code and data of security-sensitive applications against the compromised  ...  Recognizing the pressing demands to secure embedded applications, ARM TrustZone has been adopted in both academic research and commercial products to protect sensitive code and data in a privileged, isolated  ...  execution environment on ARM platforms.  ...

CryptMe: Data Leakage Prevention for Unmodified Programs on ARM Devices [chapter]

Chen Cao, Le Guan, Ning Zhang, Neng Gao, Jingqiang Lin, Bo Luo, Peng Liu, Ji Xiang, Wenjing Lou
2018 Lecture Notes in Computer Science  
This paper introduces CryptMe that integrates memory encryption and ARM TrustZone-based memory access controls to protect sensitive data against both attacks.  ...  While existing software-based memory encryption is effective in defeating physical attacks, none of them can prevent a legitimate OS function from accidentally leaking sensitive data in the memory.  ...  CryptMe enables ME for unmodified programs on the widely deployed ARM platforms.  ...
