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 Espressif ESP8266 chipset makes three-dollar ‘Internet of Things’ development boards an economic reality. According to the popular automatic firmware-building site nodeMCU-builds, in the ...

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.

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.

It leverages the Advanced Encryption Standard (AES) algorithm to perform symmetric data encryption using the secret key. The encrypted data is returned in the form of a Base64 string.

The National Institute of Standards and Technology (NIST) has selected a group of cryptographic algorithms to secure the Internet of Things (IoT) devices and the related tiny sensors and actuators.

"AES is a great algorithm," said Paul Kocher, president of Cryptography Research and cofounder of ValiCert. "If the only thing I had to worry about is someone breaking AES, that would be great." ...
