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 ...

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 ...

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, ...

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.

In the context of cryptography, a public key is an alphanumeric string that serves as an essential component of asymmetric encryption algorithms. It is typically derived from a private key, which must ...

An introduction to PKI, TLS and X.509, from the ground up. Public Key Infrastructure (PKI) provides a framework of encryption and data communications standards used to secure communications over ...

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 special rule, known only to you and your intended audience.

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 ...
