Along with Shoji Miyaguchi, he independently invented the Miyaguchi–Preneel scheme, a structure that converts a

block cipher In cryptography, a block cipher is a deterministic algorithm that operates on fixed-length groups of bits, called ''blocks''. Block ciphers are the elementary building blocks of many cryptographic protocols. They are ubiquitous in the storage a ...
