Kaweichel is a port of Blowfish for 64-bit architectures, its key size accepted is 1920-bytes, instead of 16 rounds it has 32 rounds, the double of Blowfish.
ICE is a feistel block cipher that has a variant called ICE-n that accepts any key size being a multiple of 64, for this variant the number of rounds should be multiplied by the number of 64-bits slices in the key material.
/\ These two ciphers left me doubts.
Can the security margin of any feistel block cipher be multiplied if I just multiply the number of slices of original key size of the cipher by the number of rounds (of course, multiplying the number of random keys too)?
