Intel And AMD May Have Access To Cryptographic Keys Vulnerability In The Heartbleed Chip - BitcoinEthereumNews.com
เศรษฐกิจIntel และ AMD อาจเข้าถึงช่องโหว่ของคีย์การเข้ารหัสในชิป Heartbleed06 / 15 / 2022ข่าว Bitcoin Ethereum Both Intel and AMD have CPUs that are impacted. These include AMD Ryzen CPUs desktop and laptop models from the Zen 2 and Zen 3 microarchitectures, as well as Intel Core desktop and laptop models from the ninth to eleventh generation Core microarchitectures. This assault isnt viable outside of a lab context, according to Intel Senior Director of Security Communications and Incident Response Jerry Bryant, partly because stealing a cryptographic key takes hours to days. This problem is not vulnerable to cryptographic systems that are hardened against power side-chanel attacks, he noted. Frequency side chanels are a new sort of side-chanel assault similar to Hertz Bleed (hence the name Hertz and bleeding out the data). According to the attacks research paper: In the worst-case scenario, these assaults could allow an attacker to steal cryptographic keys from previously thought-to-be safe distant servers. Researchers found a flaw in Intel and AMD central processing units (CPUs) that might be exploited by hostile actors to gain access to cryptographic keys. A vulnerability in CPUs known as Hertzbleed, according to researchers at the University of Texas at Austin, the University of Illinois at Urbana-Champaign, and the University of
