Composite Enclaves: Towards Disaggregated Trusted Execution
Moritz Schneider, Aritra Dhar, Ivan Puddu +2
The ever-rising computation demand is forcing the move from the CPU to heterogeneous specialized hardware, which is readily available across modern datacenters through disaggregate…
Frontal Attack: Leaking Control-Flow in SGX via the CPU Frontend
Ivan Puddu, Moritz Schneider, Miro Haller +1
We introduce a new timing side-channel attack on Intel CPU processors. Our Frontal attack exploits timing differences that arise from how the CPU frontend fetches and processes ins…
Prevention of Microarchitectural Covert Channels on an Open-Source 64-bit RISC-V Core
Nils Wistoff, Moritz Schneider, Frank K. Gürkaynak +2
Covert channels enable information leakage across security boundaries of the operating system. Microarchitectural covert channels exploit changes in execution timing resulting from…
