Hardening Confidential Federated Compute against Side-channel Attacks
Published 23 Mar 2026 in cs.CR and cs.DS | (2603.21469v1)
Abstract: In this work, we identify a set of side-channels in our Confidential Federated Compute platform that a hypothetical insider could exploit to circumvent differential privacy (DP) guarantees. We show how DP can mitigate two of the side-channels, one of which has been implemented in our open-source library.
