For another example, the FI function of the block cipher MISTY [8] is based upon the Feistel scheme. The Lai-Massey scheme was used for the rst time in 1990 in the design of PES (Proposed Encryption Standard) [6] by Lai and Massey.
WebThis scheme proved that if the round functions are random, then a 3-round Feistel cipher will look ran-dom to any chosen plaintext attack. For the Lai-Massey scheme it was proved that a similar result could be obtained if an orthomorphism function was added.
