A RISC-V Extension to Minimize Privileges of Enclave Runtimes
Edouard Bugnion, Neelu Shivprakash Kalani
In confidential computing, the view of the system software is Manichean: the host operating system is untrusted and the TEE runtime system is fully trusted. However, the runtime system is often as complex as a full operating system, and thus is not free fr ...
ACM2023Midas: Systematic Kernel TOCTTOU Protection
Mathias Josef Payer, Atri Bhattacharyya, Uros Tesic
Double-fetch bugs are a plague across all major operating system kernels. They occur when data is fetched twice across the user/kernel trust boundary while allowing concurrent modification. Such bugs enable an attacker to illegally access memory, cause den ...
2022PANACEA: Tunable Privacy for Access Controlled Data in Peer-to-Peer Systems
Peer-to-peer paradigm is increasingly employed for organizing distributed resources for various applications, e.g. content distribution, open storage grid etc. In open environments, even when proper access control mechanisms supervise the access to the res ...
EPFL Infoscience2010On Privacy Losses in the Trusted Agent Model (Abstract)
Tamper-proof devices are pretty powerful. They typically make security applications simpler (provided that the tamper-proof assumption is not violated). For application requiring privacy, we observe that some properties may become harder (if possible at al ...
