Advanced Encryption Standard
Advanced Encryption Standard is a specification for the encryption of electronic data. It has been adopted by the U.S. government and is now used worldwide. It supersedes DES...
(AES), together with Vincent Rijmen
Vincent Rijmen
Vincent Rijmen is a Belgian cryptographer and one of the two designers of the Rijndael, the Advanced Encryption Standard. Rijmen is also the co-designer of the WHIRLPOOL cryptographic hash function, and the block ciphers Anubis, KHAZAD, Square, NOEKEON and SHARK.In 1993, Rijmen obtained a degree...

MMB
In cryptography, MMB is a block cipher designed by Joan Daemen as an improved replacement for the IDEA cipher. Modular multiplication is the central element in the design...
, Square
Square (cipher)
In cryptography, Square is a block cipher invented by Joan Daemen and Vincent Rijmen. The design, published in 1997, is a forerunner to the Rijndael algorithm, which has been adopted as the Advanced Encryption Standard...

Noekeon
NOEKEON is a family of two block ciphers designed by Joan Daemen, Michaël Peeters, Gilles Van Assche and Vincent Rijmen and submitted to the NESSIE project in September 2000. The two ciphers are "direct mode" NOEKEON, to be used for maximum efficiency where related-key attacks are not possible,...

3-Way
In cryptography, 3-Way is a block cipher designed in 1994 by Joan Daemen, who also designed Rijndael, the winner of NIST's Advanced Encryption Standard contest....

BaseKing
In cryptography, BaseKing is a block cipher designed in 1994 by Joan Daemen. It is very closely related to 3-Way; indeed, the two are variants of the same general cipher technique....
block cipher
Block cipher
In cryptography, a block cipher is a symmetric key cipher operating on fixed-length groups of bits, called blocks, with an unvarying transformation. A block cipher encryption algorithm might take a 128-bit block of plaintext as input, and output a corresponding 128-bit block of ciphertext...
s. More recently, he co-designed the Keccak
Keccak
Keccak is a cryptographic hash function designed by Guido Bertoni, Joan Daemen, Michaël Peeters and Gilles Van Assche. Keccak is one of five finalists in the NIST hash function competition to select a SHA-3 algorithm. The authors claim 12.5 cycles per byte on an Intel Core 2 CPU...

Cryptographic hash function
A cryptographic hash function is a deterministic procedure that takes an arbitrary block of data and returns a fixed-size bit string, the hash value, such that an accidental or intentional change to the data will change the hash value...

Stream cipher
In cryptography, a stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream . In a stream cipher the plaintext digits are encrypted one at a time, and the transformation of successive digits varies during the encryption...
