The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

Usually, when you hear about broken cryptography, it’s because of some sort of nonmathematical workaround to compromise supposedly encrypted traffic—like intercepting traffic during brief periods when ...

After a multi-year competition, the U.S. National Institute of Standards and Technology (NIST) selected a suite of algorithms for standardization. For key exchange, the primary choice is the ...

On Tuesday, a team of computer scientists released a report (.PDF) documenting cryptographic problems with the Diffie-Hellman key exchange, a popular algorithm used by Internet protocols to agree on a ...

It’s actually possible for entities with vast computing resources – such as the NSA and major national governments – to compromise commonly used Diffie-Hellman key exchange groups, so it’s time for ...
