Researchers have discovered a novel classical computing method to break RSA without factoring large integers, a paradigm shift in cryptanalysis. The attack was applied to deprecated 1024-bit RSA keys on an academic CPU cluster in a handful of months, far less than previously estimated. Experts call it a potential conceptual breakthrough, though widely used RSA implementations remain safe.
Background
RSA has been the backbone of public-key cryptography for decades, with security relying on the difficulty of integer factorization. The cryptographic community has long anticipated its eventual vulnerability, especially with the advent of quantum computing, making any new classical attack method noteworthy.
