AI-Fueled Duel: Simultaneous Proofs Spark Credit Questions in Cryptography

Two independent teams used OpenAI’s GPT-5.6 Sol Ultra to tackle the same open problem in unclonable encryption, submitting arXiv preprints within about three hours of each other: MIT’s Seyoon Ragavan via a hands‑on, multi‑agent workflow, and Ananth with Amit Sahai using a bespoke UCLA system to pursue and critique the solution. The near‑simultaneous results raise questions about independent discovery and how credit is attributed in AI‑augmented research, though neither paper is peer‑reviewed yet.

Cryptology: from war codes to modern digital encryption

Cryptology is the study of secret codes, encompassing both cryptography (creating codes) and cryptanalysis (breaking them). While historically linked to spy networks, cryptology today also refers to computer algorithms that encrypt data to protect passwords and personal information, with World War II code talkers highlighted as an example of its use in practice.

Reticulum Targets a Radio-Driven Post-Internet Network

Hackaday reports on The Tech Prepper's demonstration of Reticulum, a decentralized cryptographic network stack, using high-frequency radio to envision a post‑Internet communications layer that could operate when traditional networks fail; encryption bans on ham bands complicate real-world use, but the setup shows connecting a PC to an open-source radio modem and SDR tools, with BBS-style options like modem73 as possible alternatives. While appealing to survivalists and cyberpunk hobbyists, practical mass deployment faces regulatory and technical barriers.

Quantum Basics: From Spooky Action to a New Computing Era

A plain‑language primer on quantum ideas: at tiny scales particles can be in superpositions and only take a definite state when measured, while entangled particles remain linked across distances. These quirks enable qubits that can encode many possibilities in parallel, potentially solving problems in drug design, materials science and cryptography far faster than classical computers. Real-world quantum tech is still fragile and not a substitute for everyday tasks; nonetheless, progress raises both exciting capabilities and security/ethical questions as encryption faces new risks and quantum‑safe networks develop.

ETH Zurich's Perfect Die Delivers Physics-Certified Randomness Through Quantum Entanglement

ETH Zurich researchers built a “perfect die” by entangling two qubits across a 30-meter link and refining the output with a two-source extractor to produce randomness whose unpredictability is certified by quantum physics, with potential applications in cryptography, gaming, and secure computing, showcasing quantum advantage over classical generators.

Microsoft’s Majorana 2 promises 1,000x reliability, edging quantum era forward

Microsoft unveiled Majorana 2, a topological quantum chip the company says is 1,000 times more reliable than Majorana 1, with qubits lasting up to a minute. AI-driven research and manufacturing acceleration helped speed development, pushing toward scalable quantum computing by 2029. The story also notes rising crypto concerns, as advances in quantum tech threaten Bitcoin’s cryptography and Citi warns practical quantum attacks could arrive sooner than expected.

Quantum Entanglement Delivers Certifiably Perfect Randomness

ETH Zurich researchers used a Bell-test experiment with entangled qubits separated by 30 meters and performed over a billion trials in about nine hours to demonstrate randomness amplification that transforms imperfect randomness into certifiably perfect randomness, a device-independent result that could underpin future cryptography and security systems. The work, published in Nature 2026, shows randomness that remains truly unpredictable under rigorous analysis, surpassing previous RNGs that depended on trusted hardware.

AI Cracks a 400-Year-Old Borg Cipher, Revealing Hidden Medieval Remedies

AI speeds up deciphering encrypted historical texts—like the Vatican's Borg cipher—by transcribing and decoding handwriting and symbols into digital texts, uncovering astonishing remedies and secrets once kept in archives. The Descrypt project and tools like Transkribus aim to unify transcription and decryption, enabling researchers (and the public) to unlock coded letters, diplomatic notes, and even unknown scripts, potentially rewriting parts of history and expanding access to ancient writing systems.

Quantum computers near 2029 threaten everyday encryption, triggering a looming cyber crisis

Experts warn that practical quantum computers could crack widely used encryption by around 2029, shrinking the window to secure data and forcing governments and companies to accelerate the adoption of post-quantum cryptography and related defenses. The risk includes harvest-now, decrypt-later attacks, potential threats to financial systems and health devices, and the reality that cryptographic migrations can take 10–20 years even with existing standards (NIST post-quantum algorithms) and urgency from guidance aiming for 2035. While some safeguards exist, broad, timely migration remains uncertain, underscoring the need for proactive upgrades to preserve data security in the quantum era.

Quantum Time Bomb: Crypto Could Be Cracked Sooner Than We Realize

Advances in quantum hardware and algorithms are shrinking the resources needed to break common encryption, notably elliptic-curve cryptography; while no immediate catastrophe is expected, experts urge migration to quantum-safe cryptography, with standards bodies like NIST aiming for widespread adoption by the mid-2030s and some regions piloting early post-quantum protections today.

Quantum race tightens the window on cryptography

Advances in quantum hardware and faster quantum algorithms are lowering the resources needed to crack widely used cryptography, including elliptic-curve and blockchain-based systems. While there’s no immediate catastrophe, standards bodies (like NIST) and industry players are accelerating post-quantum migrations and deploying hybrid protections, with broad adoption expected by the 2030s as the risk of a practical quantum attack grows.

NYT Narrows Satoshi to Adam Back, but Proof Isn’t Clear

The New York Times reports that British cryptographer Adam Back is the strongest publicly identified candidate for Satoshi Nakamoto after examining emails and stylistic cues, but the case remains circumstantial and Back denies being the Bitcoin creator.

NYT narrows Satoshi Nakamoto to Adam Back, but Back denies the claim

The New York Times, in a report by John Carreyrou, argues that Adam Back is Satoshi Nakamoto based on writing quirks, Hashcash links, and Cypherpunks-era posts; Back refutes the claim, saying the similarities are coincidental and that Satoshi’s anonymity may benefit Bitcoin.

Sensor-Level Signatures Could Certify Photos in Real Time

ETH Zurich researchers propose cryptographic signatures generated by a camera’s sensor at capture time and stored in a public ledger to prove authenticity and detect tampering, offering a potentially more secure alternative to the current C2PA approach that signs data later in the camera’s processor; implementation would require redesigned sensors and hardware changes, with ongoing cost considerations.
