Abstract

In this paper, we describe a 64-bit multi-round block cipher, suitable for software implementation, in which three different encryption methods are combined in a sequence determined by the user key. In this way, whilst the design is public knowledge, the actual encryption method selected by the user key is kept secret. This method has been implemented using the three block ciphers: Khufu, Loki, and a cipher by Lai and Massey. The performance and cryptanalysis results using the CRYPT-XB package for this example are provided.
