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 ...

The original version of this story appeared in Quanta Magazine. In our increasingly digital lives, security depends on cryptography. Send a private message or pay a bill online, and you’re relying on ...

The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has finalized a set of encryption algorithms designed to withstand cyberattacks from quantum computers. These ...

Two IBM-developed algorithms have been officially formalized within the world's first three post-quantum cryptography standards, which were published today by the U.S. Department of Commerce's ...

While the dawn of quantum computing may still be years away, federal agencies are facing a future threat that has already arrived. Adversaries are actively stealing encrypted government information ...

In the last section we discussed the potential for optimizing algorithms, which can be done, but sometimes may not result in the type of performance required. As was mentioned, you can always move the ...
