Even if someone copies your encrypted communications in their entirety at this very moment, they cannot yet read the contents ...

RSA succeeded beyond what its creators could have imagined. But as we approach its 50th anniversary, we are also approaching ...

When we think of encryption, it often seems like a matter of complex mathematical formulas and incredibly fast computers. Of ...

A UC San Diego-led team forged RSA signatures without extracting its key. But Bitcoin and Ethereum sign with a different ...

As noted by Ars Technica, a recent research paper by researchers from the University of California San Diego and the Université de Lorraine has revealed a novel method using classical computing that ...

The technique still takes 1,380 CPU core-years, but that's down from the estimated 500,000 to 1 million CPU core-years it takes to factor a key.

Eric Lu factored an 862-bit RSA key for $400K using GPUs, putting RSA-1024 cracking costs at $30M and accelerating post-quantum crypto timelines.

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 ...

RSA keeps getting factored. The question is what each new result tells us about the security of the encryption we still use: will the common standard of ...

RSA-896, a 270-digit encryption benchmark, was factored on September 19, 2026, by Anthropic engineer Stephen Weis using Claude AI and 2,048 GPUs -- making it the second AI-assisted integer factorizati ...

AI is continuing to break records in technical fields. An Anthropic engineer says Claude ported a decades-old factoring tool to GPUs and ran it across thousands of idle chips to break RSA-896, a ...
