• Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only Learn more The world has known for decades that the RSA cryptosystem ’s days are numbered.
• Once quantum computing becomes practical (estimates for that range from 3 to 20 or more years), the foundational security it provides will crumble.
• New research has revealed a novel method that uses classical computing to reduce the current RSA security level to an unacceptably low threshold.
• The practical risk is limited, but still significant.
• Applying the attack against the deprecated use of 1024-bit keys took a handful of months on an academic CPU cluster, significantly less than the current estimates for 1024-bit factoring that would require resources that only nations or companies with massive resources could achieve.
• Widely used RSA implementations are also safe.
