Locus: A Framework for Exploring and Optimizing Point Addition Hardware for Zero-Knowledge Proofsnew

Locus framework automates ASIC and FPGA point-addition designs for elliptic curves, achieving 2.71x speedups and 3.11x area reductions for ZKPs.

Locus is a framework that automatically generates ASIC and FPGA implementations of elliptic curve point addition (PADD) for supported equation forms, enabling exploration of over 1,000 design points. On a 12nm technology node, its designs achieve a 2.71x geomean speedup and 3.11x geomean area reduction versus prior ASICs, plus 34.67x geomean speedup over CPU. Integrated into a prior ZKP accelerator at iso-area, it yields a 3.15x geomean speedup on end-to-end proof generation. The framework is open source on GitHub.

OFAC Sanctions Chinese Scam Platform Xinbi Guarantee

US Treasury's OFAC sanctioned Chinese scam-platform Xinbi Guarantee, which processed $24bn+, and froze $52.8m in linked cryptoassets.

OFAC sanctioned Xinbi Guarantee, a Chinese-language marketplace connecting Southeast Asian scam centers and transnational crime syndicates to merchants offering financial services, technology and crypto exchange. Treasury estimates over $24bn processed since 2022, while TRM Labs estimates over $36bn, with daily inflows nearly doubling between May and December 2025. Two supporting entities were also sanctioned: SafeW Technology (Singapore) and Anwen Technology (Cambodia, maker of XinbiPay). The US Secret Service and Elliptic froze $52.8m in linked cryptoassets, and the marketplace now appears offline with its Telegram channels deleted.

First Galileo SAS Authenticated Time Solution

Researchers demonstrate the first timing solution computed from Galileo's new Signal Authentication Service, protecting receivers against GNSS spoofing.

Galileo's new Signal Authentication Service (SAS) on the E6-C signal directly authenticates ranging measurements, closing a gap left by OSNMA, which only protects navigation data. Researchers built a snapshot software receiver implementing a simplified SAS protocol and computed an authenticated receiver clock bias from recordings of both SAS-capable satellites, collected with a Septentrio SDR prototype. The results demonstrate feasible authenticated timing ahead of full SAS operational deployment.

OpenSSL 4.1.0 Alpha1 Released With DTLS 1.3 and Faster Post-Quantum Cryptography

OpenSSL 4.1.0 Alpha1 adds DTLS 1.3 support, ML-DSA and ML-KEM post-quantum optimizations, and GREASE TLS compatibility, intended for testing only.

The alpha preview of OpenSSL 4.1.0 implements RFC 9147 DTLS 1.3 for UDP-based applications and integrates DTLS into the SSL listener API. It accelerates ML-DSA signatures and ML-KEM encapsulation with AVX-512 and VAES optimizations on x86_64, and adds GREASE (RFC 8701), IKEv2 KDF support, and Elbrus2000 (e2k) targets. The release is intended for testing and development, not production, and removes Windows-on-Itanium and Windows CE build targets.
