DR.SGX: Hardening SGX Enclaves against Cache Attacks with Data Location Randomization
Ferdinand Brasser, Srdjan Capkun, Alexandra Dmitrienko +3
Recent research has demonstrated that Intel's SGX is vulnerable to software-based side-channel attacks. In a common attack, the adversary monitors CPU caches to infer secret-depend…
HardIDX: Practical and Secure Index with SGX
Benny Fuhry, Raad Bahmani, Ferdinand Brasser +3
Software-based approaches for search over encrypted data are still either challenged by lack of proper, low-leakage encryption or slow performance. Existing hardware-based approach…
Software Grand Exposure: SGX Cache Attacks Are Practical
Ferdinand Brasser, Urs Müller, Alexandra Dmitrienko +3
Side-channel information leakage is a known limitation of SGX. Researchers have demonstrated that secret-dependent information can be extracted from enclave execution through page-…
