Square (cipher)
In cryptography, Square (sometimes written 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. Square was introduced together with a new form of cryptanalysis discovered by Lars Knudsen, called the "Square attack ".
The structure of Square is a Substitution-Permutation network with eight rounds, operating on 128-bit blocks and using a 128-bit key.
Square is not patented.
