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) … [Read more...] about Single-Core CPU Cracked Post-Quantum Encryption Candidate Algorithm in Just an Hour

Researchers Break Intel SGX With New ‘SmashEx’ CPU Attack Technique
A newly disclosed vulnerability affecting Intel processors could be abused by an adversary to gain access to sensitive information stored within enclaves and even run arbitrary code on vulnerable systems. The vulnerability (CVE-2021-0186, CVSS score: 8.2) was discovered by a group of academics from ETH Zurich, the National University of Singapore, and the Chinese National … [Read more...] about Researchers Break Intel SGX With New ‘SmashEx’ CPU Attack Technique
New Class of CPU Flaws Affect Almost Every Intel Processor Since 2011
Academic researchers today disclosed details of the newest class of speculative execution side-channel vulnerabilities in Intel processors that impacts all modern chips, including the chips used in Apple devices.After the discovery of Spectre and Meltdown processor vulnerabilities earlier last year that put practically every computer in the world at risk, different classes of … [Read more...] about New Class of CPU Flaws Affect Almost Every Intel Processor Since 2011
