The Measured Costs of Randomized Caches, Counted Without Ranking

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, An antique brass cash register stands alone on a bare iron plinth, its crowded keyboard of ivory keys disfigured — the engraved numerals and letters pried loose and pressed into random seats (a 7 under the dollar key, a C where a 9 should be), the large circular total window glowing with a staggering sum that climbs higher with each silent clack, a thick forged crank protruding from the side with black speed lines radiating violently into the surrounding void, the casing slightly warped from internal strain, lit from above by a single hard beam that throws long sharp shadows across its face, all enveloped in a vast empty blackness that crushes inward.

A paper deposited on the arXiv reports the first comparative evaluation, upon a common full-system hardware platform, of four randomised cache designs proposed against side-channel attack. The designs...

Faulting the fixed step: repeated instruction skips recover CSIDH keys from deterministic variants

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, A single colossal bronze gear wheel, its one tooth snapped off at the root leaving a raw, jagged fracture with tiny glittering metal shards, mounted on an unseen axle in a vast void of absolute black; a single hard spotlight from the left edge rakes across the gear's corroded pitted surface, casting the gaping missing tooth as a sharp triangular abyss of shadow; thin white speed lines tear outward from the fracture point across the stark background, streaking diagonally and intensifying toward the edges; extreme close-up centered on the broken tooth with the surrounding gear receding into deep darkness, the empty upper and lower space creating a suffocating sense of catastrophic mechanical failure poised at a single point. [Z-Image Turbo]

Deterministic variants of CSIDH, which removed randomness to close earlier fault attacks, have been shown susceptible to a fault attack that recovers the full key, and the reference implementation of ...

New Proof Gives Fixed, Local Correction Cycle for 4D Toric Code

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, A colossal torus of fractured black volcanic glass, suspended in a blinding white void; fissures crack across its surface and from each burst a vein of incandescent white-gold liquid that flows and hardens into seamless polish; speed lines radiate from every point of the ring, a single overhead spotlight creates harsh chiaroscuro, extreme wide shot leaving vast emptiness around the singular self-mending form, conveying unbreakable structure through continuous local repair. [Z-Image Turbo]

The essential fact is this: a theorem that removes a standing obstacle to fault-tolerant quantum computation has been placed on the arXiv, under the title 'Local Quantum Fault Tolerance Without Expans...

Real-World Payout Schemes Reorder the Defensive Ranking for Pool Attacks

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, A colossal roulette wheel of tarnished brass and black steel, its perimeter lined with small iron shields instead of numbers, one slot overflowing with a pile of gold coins so heavy it cracks the wheel's rim and tilts the whole mechanism, speed lines of pale light radiating from the coin pile, hard raking light from the left casting long shadows, empty black void around the wheel, dust hanging in the air, high contrast. [Z-Image Turbo]

The relevant arithmetic has now been performed under the rules actually in use, and the ordering of defences changes. A preprint now before the field treats T-PAW, an attack family that contains FAW a...

Lower-cost ancilla purification for Majorana quantum computation through an extra stabilizer-sign comparison
