[CamelliaSpec]. Camellia specifies the 128-bit block size and 128-,
192-, and 256-bit key sizes, the same interface as the Advanced
Encryption Standard (AES). Camellia is characterized by its
suitability for both software and hardware implementations as well as
its high level of security. From a practical viewpoint, it is
designed to enable flexibility in software and hardware
implementations on 32-bit processors widely used over the Internet
and many applications, 8-bit processors used in smart cards,
cryptographic hardware, embedded systems, and so on [CamelliaTech].
Moreover, its key setup time is excellent, and its key agility is
superior to that of AES.

RFC 3713 Camellia Encryption Algorithm April 2004
Camellia has been scrutinized by the wide cryptographic community
during several projects for evaluating crypto algorithms. In
particular, Camellia was selected as a recommended cryptographic
primitive by the EU NESSIE (New European Schemes for Signatures,
Integrity and Encryption) project [NESSIE] and also included in the
list of cryptographic techniques for Japanese e-Government systems
which were selected by the Japan CRYPTREC (Cryptography Research and
Evaluation Committees) [CRYPTREC].
