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 ...

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 ...

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 ...

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, ...

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 ...

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.

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.

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 ...

Encryption, the transformation of data into a form that prevents anyone unauthorized from understanding that data, is a fundamental technology that enables online commerce, secure communication, and ...
