There have been many papers on minimalism of cryptography. Secure minimal block cipher is one of these topics and Even and Mansour suggested a simple block cipher. The Even-Mansour scheme is a block cipher with one permutation and two whitening keys. Studying related to the Even-Mansour scheme gives great insight into the security and design of block cipher. There have been suggested many trials to analyze the security of the Even-Mansour scheme and variants of the Even-Mansour scheme. We present a new variant of the Even-Mansour scheme and introduce a variant of the Even-Mansour scheme. We focus on the security of these variants of the Even-Mansour scheme and present variation of the security according to key size. We prove the security of a variant of the Even-Mansour scheme and show that a generalized Even-Mansour scheme is not proper for a minimal block cipher.
