Key Centered Quantum Cryptanalysis - The Threat is much closer now!

The original strategy for quantum cryptanalysis was math-centered, circumventing the complelxity that protected users from violating one-way function defense. All estimates regarding the imminence of the quantum cryptanalytic threat were based on this strategy.

The new strategy calls for crypto-dedicated quantum gates that hone on the fact that the secret key is used in its entirety for the duration of its use, and all the transmitted ciphertexts reflect the same key. The key size is known, only its bit identities are secret. The computation starts where each possible key has a chance of 1 / |K| to be the right key, where |K| is the number of possible keys. The dedicated entangled gates quite quickly build a spiked probability curve that points to smaller and smaller set of high probability keys, until the right key is flushed out.

This 'full key use' vulnerability that permeates all main stay ciphers is vanishing with pattern devoid cryptography in which every message relies on a randomly selected, randomly sized, part-key.

As quantum cryptanalysis moves forward, so does pattern devoid cryptography.
