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 ...
ACM2023TEEzz: Fuzzing Trusted Applications on COTS Android Devices
Mathias Josef Payer, Marcel Busch
Security and privacy-sensitive smartphone applications use trusted execution environments (TEEs) to protect sensitive operations from malicious code. By design, TEEs have privileged access to the entire system but expose little to no insight into their inn ...
IEEE COMPUTER SOC2023Maneuvering the odds: The dynamics of venture capital decision-making
Research Summary: This article investigates venture capital (VC) decision-making, a process that occurs under changing conditions and limited, ambiguous information. We shed new light on the inherent dynamics of this strategic process. One of the key disti ...
WILEY2023Attestable Software Versioning for Stateful Confidential Computing
Edouard Bugnion, Charly Nicolas Lucien Castes
Trusted execution environments enable the creation of confidential and attestable enclaves that exclude the platform and service providers from the trusted base. From its initial attestable state, a stateful enclave such as a confidential database can hold ...
2022DARKFLUX: A new tool to analyze indirect-detection spectra of next-generation dark matter models
We present DARKFLUX, a software tool designed to analyze indirect-detection signatures for next-generation models of dark matter (DM) with multiple annihilation channels. Version 1.0 of this tool accepts user-generated models with 2 -> 2 tree-level dark ma ...
ELSEVIER2022mu RAI: Securing Embedded Systems with Return Address Integrity
Embedded systems are deployed in security critical environments and have become a prominent target for remote attacks. Microcontroller-based systems (MCUS) are particularly vulnerable due to a combination of limited resources and low level programming whic ...
