'''E2''' is a [[block cipher]] from [[Nippon Telephone and Telegraph]]. It was candidate in the [[AES competition]] but did not make it into the finals. Like all AES candidates, it uses 128-bit blocks and supports key sizes of 128, 192 or 256 bits. It is a 12-round Feistel network using a single 8 by 8 S-box.

E2 is a block cipher from Nippon Telephone and Telegraph. It was candidate in the AES competition but did not make it into the finals. Like all AES candidates, it uses 128-bit blocks and supports key sizes of 128, 192 or 256 bits. It is a 12-round Feistel network using a single 8 by 8 S-box.

There has been no published cryptanalysis of the full E2, but there is an attack on a reduced-round version [1].

Camellia shares some design features with E2 and has largely replaced it.
