#dilithium

Dear Technical Trekkie,

Ah, yes! I know the universe of which you speak—one of several universes recently afflicted by a higher-dimensional brush with the wider Omniverse. I should warn you, however, that the effects of the Shroud and general omniversal interference make it difficult to clearly view events in this timeline; from my current vantage point, I can only see glimpses of one branching timeline…

With the Decepticons under lock and key, the Klingons eventually turned their attention to studying the mechanical physiologies of their captives and attempting to reverse-engineer their weapon systems. Indeed, the aliens soon developed a frightful array of experimental weapons—although the need to synthesize an artificial dilithium-energon mixture to power these weapons of war made them impractical for long-term military use.

Every era has its defining cybersecurity challenge. In the early 2000s, it was worms and viruses. The 2010s brought ransomware and state-sponsored intrusions. Now, the 2020s have begun a race against time toward what experts ominously call Q-Day—the moment when a sufficiently powerful quantum computer could break widely used public-key cryptography. This is not science fiction. Algorithms like…

NIST 選出了四個 Post-Quantum Cryptography 演算法

NIST (NSA) 選出了四個 Post-quantum cryptography 演算法 (可以抵抗量子電腦的演算法)：「NIST Announces First Four Quantum-Resistant Cryptographic Algorithms」。 四個演算法分別是： CRYSTALS-Kyber：對稱加密。 CRYSTALS-Dilithium：數位簽名。 FALCON：數位簽名。 SPHINCS+：數位簽名。 這次沒看到非對稱加解密的演算法… 然後翻了 Hacker News 上的討論，果然一堆人在討論 NIST 能不能信任的問題：「NIST Announces First Four Quantum-Resistant Cryptographic Algorithms (nist.gov)」。 然後據說 Kyber 這個名字出自 Star…
