Abstract

We present a family of block ciphers that can be implemented very efficiently on cheap Smartcard processors. The ciphers use a very small amount of RAM and a reasonable amount of ROM. Both cipher execution and key setup/key change are very fast. The ciphers resist theoretical and practical cryptanalytic attacks and in their design timing and power analysis attacks have been taken into account.
