양자컴퓨터가 타원곡선 암호를 깨는 데 필요한 큐비트 수를 크게 줄였다는 새로운 연구가 소개됐다. 이 연구는 HTTPS 연결, 디지털 서명, 암호화폐 지갑을 보호하는 핵심 암호체계의 안전성에 대한 우려를 키우며, 양자암호/보안 분야에 중요한 시사점을 준다.
A new research work dramatically reduces the amount of qubits to break elliptic curve ciphers on a hypothetical quantum computer. Elliptic curve crypto is the math protecting most HTTPS connections, digital signatures, and cryptocurrency wallets. Shor's quantum algorithm can
Called it.
In Nov I wrote that ECC was the easier quantum target: postquantum.com/post-quantum/shor-rsa-ecc-diffie-hellman/
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:
P-256: 2,124 → 1,193 (42% less than RSA-3072!)
P-224: 1,098 (21.5% less than RSA-2048)

15 Mar 2026 - When Clémence Chevignard, Pierre-Alain Fouque, and André Schrottenloher submitted their latest paper to EUROCRYPT 2026, they already had a track record that the cryptographic community was watching closely. In 2024, the same team at INRIA Rennes had published a method that slashed the qubit requirements for quantum factoring of RSA integers - work that Craig Gidney at Google Quantum AI subsequently used as a foundation to bring the estimated physical qubit cost of breaking RSA-2048 from 20 million down to under one million. That result sent tremors through every risk committee tracking quantum timelines. Now the

Способы Повышения Надежности Встраиваемого ПО
В этом тексте я бы хотел перечислить способы повышения надежности для встраиваемого ПО. Cуществует много приемов, которые помогают повысить надежность встраиваемого ПО. Как прошивка может противостоять всяческим флунктуациям во время своей работы и обезопасить себя от зависания или повреждения исходных данных?
