In September 1997, the NIST issued a request for possiblecandidates for a new AES to replace the DES. In August 1998, NISTselected 15 candidate algorithms and in August 1999, announced fivefinalists: ...

The AES algorithm is a fixed-width encryption algorithm. Therefore, the input message is first padded to make sure that it will completely fit in “n” number of 128-bit blocks.

This article will focus on applying AES encryption and hash authorization functions to the MQTT protocol using the popular ESP8266 chip running NodeMCU firmware.

So, in 2001, the Advanced Encryption Standard (AES) was finalized and published. AES is designed to use much bigger keys - 128, 192 or 256 bits in size - making brute force attacks much, much harder.

[Part 1 of this article begins with a review of various application security level categories and a look at hash algorithms as a basic level of security. Part 2 covers the basics for optimizing ...

Reports began surfacing in October that Chinese researchers used a quantum computer to crack military-grade AES 256-bit encryption. Those reports turned out to be wrong, but that did little to dampen ...

In a paper published in Science China Information Sciences, an international team of scientists presents a variational quantum attack algorithm (VQAA) for symmetric cryptography. As exemplified by ...
