Here comes the fastest public-key algorithm that most people have never heard of: It's called NTRUEncrypt and this month was approved by the financial services standards body, the Accredited Standards ...

In July, the National Institute of Standards and Technologies selected four cryptography algorithms as national standards for public key security in order to prepare for an era of quantum computers, ...

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

Quantum security is not just about new algorithms – operators must tackle key issues and untangle crypto sprawl before ...

Seems to me that the Diffie-Hellman key agreement protocol results in a symmetric shared private key. However, the books I've used for Security+ prep put it with RSA as a public-key algorithm.

Public-key encryption, as noted in the profile of cryptographer Bruce Schneier, is complicated in detail but simple in outline. The article below is an outline of the principles of the most common ...

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 ...

When I began programming microcontrollers in 2003, I had picked up the Atmel STK-500 and learned assembler for their ATtiny and ATmega lines. At the time I thought it was great – the emulator and ...

We don’t know when, but it will happen: Quantum computers will become so powerful that all existing public-key cryptography protections will be quickly crackable. According to Dr. Mark Jackson of ...
