A universal whitening algorithm for commercial random number generators

alinta — 2024-10-17T11:34:35+02:00

In this work, we present a universal whitening algorithm using n-qubit permutation matrices to remove the imperfections in commercial random number generators without compression. Specifically, we demonstrate the efficacy of our algorithm in several categories of random number generators and its comparison with cryptographic hash functions and block ciphers.

Breaking 256-bit Elliptic Curve Encryption with a Quantum Computer

ccx — 2022-02-11T03:10:07+01:00

Finally, we calculate the number of physical qubits required to break the 256-bit elliptic curve encryption of keys in the Bitcoin network within the small available time frame in which it would actually pose a threat to do so. It would require 317 × 106 physical qubits to break the encryption within one hour using the surface code, a code cycle time of 1 μs, a reaction time of 10 μs, and a physical gate error of 10-3. To instead break the encryption within one day, it would require 13 × 106 physical qubits.

Recherchen von ZDF, Washington Post und SRF belegen, dass BND und CIA grobe Menschrechtsverletzungen verschwiegen, als sie heimlich Staaten ausspionierten.

Seriously, stop using RSA | Trail of Bits Blog

Found linked from Whose Curve Is It Anyway <https://whosecurve.com/>. | Here at Trail of Bits we review a lot of code. From major open source projects to exciting new proprietary software, we’ve seen it all. But one common denominator in all of these systems is that for some inexplicable reason people still seem to think RSA is a good cryptosystem to use. Let me save…

E-Mails verschlüsseln - lohnt sich das?

thtbln — 2018-04-17T21:56:05+02:00

E-Mail-Verschlüsselung ist seit Jahren ein Thema. Und seit Jahren setzt sie sich nicht durch. Das hat verschiedene Gründe. Wir zeigen trotzdem, wie es geht.
