He is very closely associated with 3-WAY ; indeed, they are variants of the same general encryption technique.

Description
BaseKing has a block size = 192 bits, which is two times longer than 3-WAY. The key length is also 192 bits.
History
In his dissertation, Dimen presented an extensive theory of block ciphers, as a fairly general cipher algorithm, composed of many reversible transformations that can be chosen with considerable freedom.
He discussed the security of this general scheme against known attacks and gave two specific examples of ciphers consisting of specific choices for variable parameters. These ciphers are 3-WAY and BaseKing.
BaseKing is susceptible to the same kind of attacks as 3-WAY. Dimen, Michaël Peeters, and also demonstrated a potential vulnerability to differential analysis , along with a small number of methods to increase the resistance of this BaseKing implementation to such an attack.
