    Research News ECDLP Challenge Ladder

    New Paper Alert: Brace for Impact: New ECDLP Challenge Ladder Benchmarks Quantum Threat to Bitcoin

    The “Brace for Impact” ECDLP challenge suite is a great attempt to translate a looming cryptographic crisis into a concrete set of problems we can grapple with today. It provides a much-needed “ruler” to measure where we stand in the race between encryption and quantum decryption. The choice of Bitcoin’s secp256k1 curve for these challenges ties the abstract math to…

    Research News Quantum Breakthrough Slashes Qubit Needs for RSA-2048

    Quantum Breakthrough Slashes Qubit Needs for RSA-2048 Factoring

    A new research preprint by Google Quantum AI scientist Craig Gidney has dramatically lowered the estimated resources needed to break RSA-2048 encryption using a quantum computer. Gidney’s May 2025 paper, “How to factor 2048 bit RSA integers with less than a million noisy qubits,” argues that a fault-tolerant quantum computer with under 1 million qubits could factor a 2048-bit RSA…

    Research News Execution Times Kyber and Dilithium

    New Study Shows Post‑Quantum Cryptography (PQC) Doesn’t Have to Sacrifice Performance

    The new performance analysis of Kyber and Dilithium is a welcome addition to the PQC literature. It confirms that post‑quantum security and good performance are not mutually exclusive, especially when using optimized implementations. In fact, Kyber and Dilithium often outperform classical cryptography at comparable security levels. This challenges the narrative that PQC will drastically slow down our networks. At the…

    Research News RSA-2048 Factorization BS

    First Successful Factorization of RSA-2048 by Quantum Computer? Not Even Close!

    Chinese researchers published “A First Successful Factorization of RSA-2048 Integer by D-Wave Quantum Computer.” To get straight to the point - the title is misleading. The authors did NOT factor a general RSA-2048 key (as used in real cryptography); instead, they factored a specially structured 2048-bit semiprime chosen to be extremely easy.
