Why are they having "great difficulties" when the kernel already supports two
other "KCMVP-approved block ciphers", ARIA and SEED?  Why aren't they using
dm-crypt with ARIA or SEED?

And does LEA (or SEED or ARIA) support in Linux actually solve that problem?
Just adding support for these algorithms to Linux does not mean that Linux
automatically becomes a "KCMVP validated cryptographic module", right?  Do you
have a complete plan that would actually solve the claimed problem?
