Empirical Analysis of Randomness Quality in Differential Privacy Mechanisms

Differential Privacy DP relies on carefully calibrated random noise to protect individual privacy in statistical analyses. While theoretical work has analyzed DP under weakened randomness assumptions, the practical consequences of entropy degradation remain poorly understood. We present a...

CVE-2024-21977

Incomplete cleanup after loading a CPU microcode patch may allow a privileged attacker to degrade the entropy of the RDRAND instruction, potentially resulting in loss of integrity for SEV-SNP guests...
