Post-quantum migration gets harder when every user holds a key
Quantus CEO Christopher Smith discusses post-quantum migration pitfalls, including oversized keys breaking IPsec, SSH and TLS, and hard-to-migrate blockchain user keys.
Quantus CEO Christopher Smith describes post-quantum migration findings from banks and hospitals, including forgotten default passwords, orphaned admin keys held by former employees and hidden password hashes on user devices. Larger post-quantum keys and signatures break size assumptions in IPsec, SSH, TLS and libp2p, while migrating blockchain user keys remains hard because every user must act. He argues boards should fund quantum migration like insurance by quantifying cryptographic failure risk, and warns a silent quantum break would be difficult to detect from outside.
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.
