Single-Core CPU Cracked Post-Quantum Encryption Candidate Algorithm in Just an Hour

Single-Core CPU Cracked Post-Quantum Encryption Candidate Algorithm in Just an Hour
Aug 03, 2022
A late-stage candidate encryption algorithm that was meant to withstand decryption by powerful quantum computers in the future has been trivially cracked by using a computer running Intel Xeon CPU in an hour's time. The algorithm in question is SIKE — short for Supersingular Isogeny Key Encapsulation — which made it to the  fourth round  of the Post-Quantum Cryptography (PQC) standardization process initiated by the U.S. Department of Commerce's National Institute of Standards and Technology (NIST). "Ran on a single core, the appended  Magma   code  breaks the Microsoft  SIKE challenges  $IKEp182 and $IKEp217 in about 4 minutes and 6 minutes, respectively," KU Leuven researchers Wouter Castryck and Thomas Decru  said  in a new paper. "A run on the SIKEp434 parameters, previously believed to meet NIST's quantum security level 1, took about 62 minutes, again on a single core." The code was executed on an Intel  Xeon CPU E5-2630v2  at 2.60GHz, which w

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms
Jul 06, 2022
The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has  chosen  the first set of quantum-resistant encryption algorithms that are designed to "withstand the assault of a future quantum computer." The post-quantum cryptography ( PQC ) technologies include the  CRYSTALS-Kyber  algorithm for general encryption, and  CRYSTALS-Dilithium ,  FALCON , and  SPHINCS+  for digital signatures. "Three of the selected algorithms are based on a family of math problems called structured lattices, while SPHINCS+ uses hash functions," NIST, which kicked off the standardization process in January 2017,  said  in a statement. Cryptography, which underpins the security of information in modern computer networks, derives its strength from the difficulty of solving mathematical problems — e.g., factoring large composite integers — using traditional computers. Quantum computers, should they mature enough, pose a  huge impact  on the current pu

How to transform your revolutionary idea into a reality: $100K Nokia Bell Labs Prize
Apr 15, 2020
Revolutionary ideas in science, technology, engineering, and mathematics don't occur every day. But when those "eureka" moments happen, we need to provide a forum to explore those ideas, judge them on their merits, and distinguish the extraordinary from the merely good. Once a year, Nokia Bell Labs makes that forum a reality, where robust proposals that have the potential to revolutionize the future of human experience are presented and debated. If you think your idea could be one of them, the Nokia Bell Labs Prize is for you. Solving challenges that connect humans, systems, things, infrastructure, or processes, the 2020 Nokia Bell Labs Prize is an opportunity for innovators around the world to collaborate with world-renowned Nokia Bell Labs researchers and transform their ideas into prototypes of the future. What kind of ideas are we talking about? Big, bold, and bordering on audacious, they should have far-reaching, humanity-changing implications. Previous

NIST Calls Development of Quantum-Proof Encryption Algorithms

NIST Calls Development of Quantum-Proof Encryption Algorithms
Dec 22, 2016
Quantum Computers – Boon or Bane? Quantum computers can perform operations much more quickly and efficiently even with the use of less energy than conventional computers, but that's bad news for encryption — a process which scrambles data according to a massively complex mathematical code. In theory, quantum computers can break almost all the existing encryption algorithms used on the Internet today due to their immense computing power. Quantum computers are not just in theories; they're becoming a reality. With countries like China that holds the top two position in the world's most powerful supercomputers (Sunway TaihuLight and Tianhe-2), followed by the United States' Titan, the day is not far when Quantum computers will work on an industrial scale. Although it's hard to move quantum computing to an industrial scale, it has become a matter of concern for the United States' National Institute of Standards and Technology (NIST) over the fact that

Quantum Teleportation — Scientists Teleported Quantum Data over 60 Miles
Sep 28, 2015
We are just one step closer to creating a Harry Potter or ' Star Trek '-style Transporter. However, When we talk about Teleportation, we don't typically mean Teleporting any matter from one place to another as in the Science-fiction Movies. Rather, Teleportation involves capturing the essential information about something — its " quantum state ", to recreate it exactly someplace else. A month ago, The Hacker News had reported the battle between Quantum computers and Encryption . Now, with the development of technology, the NIST Scientists have set a new record in the field of " Quantum Teleportation ", as they successfully Teleported a small amount of data ( called 'qubit' ) inside light particles over a distance of 60 miles ( 100 km ) through a network of optical fiber. Teleportation enables transfer of ' Quantum state ' of a Photon to another Photon in the same state residing remotely at a far-off distance. This Record being farthest than t

Sometimes, instead of black and white we tend to look out, how a grey would look? Yes, today we are going to discuss the 'entangling' or 'superpositioning' which is a power packed functionality of quantum computers. And simultaneously, how can they pose a threat when fully launched in the world. Superposition is a state in which a system can be in multiple stages i.e. it can be 'up' and 'down' at the same time. The Quantum systems can hit different modules of a problem simultaneously, split across possible versions of the universe. What are Quantum Computers? Quantum computers are going to be the next huge development in computing for processing data, with an ability to perform calculations thousands of times faster than today's modern supercomputers. Quantum computing is not well suited for tasks such as word processing and email, but it is ideal for tasks such as cryptography, modeling and indexing enormous databases. A quantum computer can compute in min
