Don'T Hash Me like That: Exposing and Mitigating Hash-Induced Unfairness in Local Differential Privacy

Local differential privacy LDP has become a widely accepted framework for privacy-preserving data collection. In LDP, many protocols rely on hash functions to implement user-side encoding and perturbation. However, the security and privacy implications of hash function selection have not been...

SUSE-SU-2025:02075-1 Security update for the Linux Kernel (Live Patch 59 for SLE 12 SP5)

This update for the Linux Kernel 4.12.14-122225 fixes several issues. The following security issues were fixed: - CVE-2024-56601: net: inet: do not leave a dangling sk pointer in inetcreate bsc1235231. - CVE-2024-50279: dm cache: fix out-of-bounds access to the dirty bitset when resizing...

Fair Data Exchange with Constant-Time Proofs

The Fair Data Exchange FDE protocol introduced at CCS 2024 offers atomic pay-per-file transfers with constant-size proofs, but its prover and verifier runtimes still scale linearly with the file length n. We collapse these costs to essentially constant by viewing the file as a rate-1 Reed-Solomon...
