AES key schedule
AES uses a key schedule to expand a short key into a number of separate round keys. The three AES variants have a different number of rounds. Each variant requires a separate 128-bit round key for eac
Rijndael MixColumns
The MixColumns operation performed by the Rijndael cipher, along with the ShiftRows step, is the primary source of diffusion in Rijndael. Each column is treated as a four-term polynomial which are ele
Rijndael S-box
The Rijndael S-box is a substitution box (lookup table) used in the Rijndael cipher, on which the Advanced Encryption Standard (AES) cryptographic algorithm is based.
AES implementations
There are various implementations of the Advanced Encryption Standard, also known as Rijndael.
Advanced Encryption Standard process
The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process last
Crypto-PAn (Cryptography-based Prefix-preserving Anonymization) is a cryptographic algorithm for anonymizing IP addresses while preserving their subnet structure. That is, the algorithm encrypts any s
Poly1305 is a universal hash family designed by Daniel J. Bernstein for use in cryptography. As with any universal hash family, Poly1305 can be used as a one-time message authentication code to authen
Everykey designs and builds a patented universal smart key that can unlock devices and log into online accounts on those devices. The idea began as an entrepreneurship class project at Case Western Re
AES instruction set
An Advanced Encryption Standard instruction set is now integrated into many processors. The purpose of the instruction set is to improve the speed and security of applications performing encryption an
Intel Cascade Cipher
In cryptography, the Intel Cascaded Cipher is a high bandwidth block cipher, used as an optional component of the DRM scheme of the Microsoft Windows Vista operating system. The cipher is based on Adv
Advanced Encryption Standard
The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), is a specification for the encryption of electronic data established by the U.S. Na
