Proximity Gaps for Gabidulin Codes and Applications
Researchers prove proximity-gap bounds for rank-metric and Gabidulin codes, enabling the first polynomial commitment scheme framework based on rank-metric error-correcting codes.
The paper proves every linear rank-metric code admits a proximity gap for deltas up to (d-1)/(3n) with error at most q^(e+1)/q^m, and improves the gap to (d-1)/(2n) for Gabidulin codes with error at most 10q^(n-1)/q^m, matching bounds for Reed-Solomon codes. A constructed infinite family of constant-rate Gabidulin codes shows the (d-1)/(2n) bound is tight, and a counterexample establishes a lower bound on the error at the d/(3n) gap. Applications include an IOPP for interleaved Gabidulin codes adapted from the Ligero IOPP and a q-linearized polynomial commitment scheme adapted from Ligero-based PCS, reportedly the first PCS framework based on rank-metric codes.

IAM Compliance Requirements and Best Practices
A guide maps IAM compliance requirements across SOX, PCI DSS, HIPAA, ISO 27001 and NIST 800-53, urging verified enforcement over documented policies.
The guide argues IAM compliance requires demonstrating that access controls are enforced at runtime, not merely documented, highlighting gaps between policy intent and application-layer execution. It maps recurring requirements across SOX ITGCs, PCI DSS v4.0, HIPAA, ISO/IEC 27001:2022, NIST SP 800-53 and GDPR, covering least privilege, separation of duties, access certification and audit trails. It recommends continuous, evidence-backed verification and application-layer telemetry instead of relying on identity provider logs or quarterly access reviews.
