Post-Quantum Encryption | Breaking Cybersecurity News | The Hacker News

Most people are barely thinking about basic cybersecurity, let alone post-quantum cryptography. But the impact of a post-quantum world is coming for them regardless of whether or not it's keeping them up tonight.  Today, many rely on encryption in their daily lives to protect their fundamental digital privacy and security, whether for messaging friends and family, storing files and photos, or simply browsing the web. The question experts have been asking for a long time, with their eye on the advances in quantum computing, is, "How long before these defenses fail?"  The ticking clock of quantum computing One set of researchers is already sounding the alarms,  claiming  that they've found a way to break 2048-bit RSA encryption with a quantum computer. While the claims may be premature, they hint toward a scary future that is perhaps closer than we once thought. Breaking RSA encryption would represent a massive privacy and security vulnerability for virtually every...

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 ...
