Attestable 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 ...

Secured Routines: Language-based Construction of Trusted Execution Environments

James Richard Larus, Edouard Bugnion, Adrien Ghosn

Trusted Execution Environments (TEEs), such as Intel SGX enclaves, use hardware to ensure the confidentiality and integrity of operations on sensitive data. While the technology is available on many processors, the complexity of its programming model and i ...

Interference-Resilient Information Exchange

Rachid Guerraoui, Seth Gilbert

This paper presents an efficient protocol for reliably exchanging information in a single-hop, multi-channel radio network subject to unpredictable interference. We model the interference by an adversary that can simultaneously disrupt up to t of the C ava ...

Self-organized public-key management for mobile ad hoc networks

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

In contrast with conventional networks, mobile ad hoc networks usually do not provide on-line access to trusted authorities or to centralized servers and they exhibit frequent partitioning due to link and node failures and to node mobility. For these reaso ...

Self-Organized Public-Key Management for Mobile Ad Hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

In contrast with conventional networks, mobile ad hoc networks do not provide on-line access to trusted authorities or to centralized servers. For this reason, key management is particularly difficult to implement in such networks. The solutions published ...
