at some point, i'd love to work on an implementation of the #screenreader of NVDA #nvda #remote / #nvdaremote where rather than using a 6-digit key that can be guessed, it uses #asymmetric #cryptography that genrates #encryption #keys using an algorithm like #rsa / #ecc (eliptic curve cryptography) in order to secure the connections. how it would work is you setup your connection. then, you'll get an encryption key for your session unique to that session. then, you give the user of the computer you want to control or who you want to control your computer the key. once both sides disconnect, the key automatically / automagically expires. it would be like a public / private keypare, where the key is stored on the server terminating the remote session (E.G. nv.seedy.cc, poweredge-r720.featherback-firefighter.ts.net) while the private key is stored on the machines connected to it. and optionally, a passfraze for the key to protect access even if that person has the key, sourt of like how #ssh public/private keypares work.

Структурные аномалии базовых точек secpXXXk1: криптоанализ Биткоина и практическое моделирование в Google Colab

В данной статье в качестве криптоанализа Биткоина разберём вычислительный научный эксперимент, воспроизводящий и расширяющий наблюдение John Zweng (2025) относительно точек-генераторов G семейства кривых Коблица SEC 2 — secp160k1, secp192k1, secp224k1 и secp256k1 . Обнаруженная закономерность: для всех кривых Кобица простого порядка семейства SEC 2 (secp160k1, secp192k1, secp224k1, secp256k1) точка, получаемая «делением» генератора G на 2 (умножением на обратный элемент 2 по модулю порядка подгруппы n ), имеет x -координату аномально малой битовой длины и содержит общую 152‑битную гексадецимальную подстроку 8ce563f89a0ed9414f5aa28ad0d96d6795f9c6 . Мы даём математическую формализацию операции, воспроизводим вычисления с помощью открытых скриптов на Python/SageMath, обсуждаем историческую непрозрачность стандарта SEC 2 , а также — в отдельных разделах — протокольные следствия для Bitcoin, включая принципы NUMS-точек, аудит вторичных генераторов и безопасность ECDSA/Schnorr . Особое внимание уделяется практическим скриптам для Google Colab, которые позволяют каждому исследователю независимо верифицировать находку. Johannes Zweng известный в GitHub в своём архиве прямо ссылается на выступление криптографа Nadia Heninger , посвящённое открытым вопросам происхождения стандартных кривых, как на дополнительный источник контекста для данной аномалии. Хенингер является одним из ведущих специалистов по практическому криптоанализу реализаций ECC/RSA (в частности, известна работами по атакам на слабую случайность при генерации ключей), и её внимание к теме подчёркивает значимость подобных архивных находок для сообщества академической криптографии.

New ECDLP resource estimate: 835 logical qubits for secp256k1, the lowest published figure for a 256-bit ECC curve. The paper (arXiv:2607.13816) supersedes the same team's April preprint at 1,333.

The tradeoff matters for threat modeling: this circuit uses ~20x more Toffoli gates than the Babbush (Google) and Schrottenloher alternatives. Fewer qubits = narrower machine. More gates = longer computation = harder to keep fault-tolerant. The paper provides no depth analysis and lists it as an open question. Whether 835 qubits with 1.7B Toffoli gates is cheaper to build and operate than 1,175 qubits with 80M gates is not answered.

Craig Gidney (Google) noted the gate count was ~100x better than he expected, and that the authors used exact (non-approximate) circuits. Approximate arithmetic would likely compress the gates further.

For PQC migration planning: this confirms the algorithmic track for ECDLP-256 is maturing. The uncertainty in when ECC breaks sits on the hardware/QEC side. Your migration schedule should be set by CNSA 2.0 deadlines and data lifetimes, not by these estimates.

Corrected comparison table and full analysis (the paper's abstract carries a stale Chevignard number): https://postquantum.com/security-pqc/ecc-secp256k1-835-logical-qubits/

An open competition has driven the logical qubit cost for one secp256k1 point addition into the high 1,100s. I traced where circuit optimization hits its hard floor - the arithmetic bound beyond which no algorithmic trick can reduce the cost further.

That floor is lower than most threat assessments assume.

I'm still sad that I apparently damaged my old Asus Pro WS X570-ACE motherboard when removing the CPU (due to failed cooler). There aren't any good AM4 motherboards now. The gamer ones don't support ECC UDIMMs, and the cheap ones that do support ECC have poor PCIe configurations. I need 3 x8 PCIe slots.
I ended up with a Gigabyte X570 Aorus Elite. It supports ECC, and has 3 x16 slots, but the actual lanes to the x17 slots are x16, x4, and x1.

In March I argued Bitcoin's quantum risk was underestimated because everyone used RSA benchmarks: postquantum.com/post-quantum/bitcoin-quantum-risk-closer-ecc/

EUROCRYPT 2026 just confirmed both.

Chevignard, Fouque & Schrottenloher halved ECDLP qubit counts:

@dalite ECC on AM4 is a solid move for a database server. The Ryzen 5000 series (especially the 5600G) supports unbuffered ECC on most B550 boards, though ASUS tends to be more reliable for ECC than Gigabyte in that generation.

For flash-heavy database workloads, even a consumer NVMe with a DRAM cache outperforms most SATA SSDs significantly. ZFS with ECC + NVMe SLOG is a strong combo if you end up going that route.

Shoutout to Proton support - they helped me reset my Drive volume entirely.

The difference between RSA2048 and Curve25519 (ECC) on mobile is night and day. Loading is now instant, and the "thermal throttling" is gone.

Moral of the story: Modern crypto isn't just about security, it's about accessibility and efficiency.

Now my data is encrypted by my own key, and the system actually feels "functional" for the first time.

Das wäre schlimm, wenn es um Verherrlichung ginge. Linus Torvalds benutzt -was so berichtet wird- seine Computer sehr lange. In der Sendung begründet er seine Anforderungen. Er möchte einen zuverlässigen und leise laufenden PC, mit guten Bauteilen, der lange hält.
Neben der Linux-Eignung der HW kommt es ihm auf ein durchgängiges #ECC (Error Correcting Code) an. Beim Kernel-Kompilieren kann er so Hardware-verursachte Fehler erkennen - war mir total neu.
