A team of researchers from UC San Diego showed that a 1024-bit RSA signature can be forged by sending multiple queries to a ...

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 ...

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

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 ...

Microsoft has quietly announced plans to deprecate TLS server authentication certificates using RSA keys with key lengths shorter than 2048 bits. The change means that it will not be possible to use ...

The National Institute of Standards and Technology (NIST) has recommended minimum key sizes of 2048-bits for the Digital Signature Algorithm (DSA), Rivest-Shamir-Adleman algorithm (RSA) and ...

Website owners take notice: In weeks, Mozilla products including its popular Firefox browser will stop trusting an unknown number of SSL certificates that were issued using old root CA certificates ...

When Mozilla released Firefox 32 last week, the company removed several root certificates from the trust store for the browser. The move wasn’t because the certificates were fraudulent or the CAs that ...

What is a kilobit equal to? The answer is 1,000 bits, but some people say it should really be 1,024. The debate over how many bits are in a kilobit has popped up many places (including in our comments ...
