KCipher-2 is not new: it was presented in 2007, making it an almost 8
years old cipher. To have two different teams with two interoperable
implementations, I suppose we need to talk to the user-agent developers,
as Ryan mentioned before?

Please find a security evaluation report of KCipher-2 by CRYPTREC:
http://www.cryptrec.go.jp/estimation/techrep_id2010_2.pdf The CRYPTREC
has evaluated KCipher-2 and selected it as a governmental standard
cipher. ISO has also confirmed the security of KCipher-2 during its
standardisation process.

Thanks,
Anirban
