2048XKS - A Software Oriented High Security Block Cipher

Dieter Schmidt

Abstract: The block cipher 2048XKS is a derivative of the block ciphers 1024 and 1024XKS, which in turn used the block ciphers MMB, SAFER, and Blowfish as building blocks. The block cipher 2048XKS has a block size of 2048 bis and a key length of 4096 bits and 8192 bits, respectively. 2048XKS is a Substition-Permutation-Network (SPN). It is designed for 32 bit microprocessors with a hardware integer multiplier.
