ABC - A Block Cipher

Dieter Schmidt

Abstract

The author proposes a block cipher wich is easy to implement in software on modern 32 bit microprocessorsThe building blocks of the cipher are from the block ciphers MMB and SAFER. The cipher may be expanded for use with future 64 bit processors. Also a new diffusion layer, developed from the SAFER diffusion layer is proposed. It has complextity and the author conjectures that it is MDS. Diffusion layers currently known to be MDS are based on matrices and thus have complexity .

Note: Revision due to typeset error and new information regarding intellectual property status of block cipher MMB
