Grand Cru (cipher)

（重定向自GRAND CRU）

In cryptography, Grand Cru is a block cipher invented in 2000 by Johan Borst. It was submitted to the NESSIE project, but was not selected.

Grand Cru is a 10-round substitution-permutation network based largely on Rijndael (or AES). It replaces a number of Rijndael's unkeyed operations with key-dependent ones, in a way consistent with the security purposes of each operation. The intent is to produce a cipher at least as secure as Rijndael, and perhaps much more secure. The block size and key size are both 128 bits, and the key schedule is the same as Rijndael's.
