	Horst Feistel - Biocrawler (Site not responding. Last check: 2007-10-26)
		He lends his name to the Feistel network construction — a common method for constructing encryption algorithms — and his work at IBM led to the development of the pioneering Lucifer and Data Encryption Standard (DES) ciphers.
		Feistel was born in Berlin in 1915, and moved to the United States in 1934.
		Feistel obtained a Bachelor's degree at MIT, and his Master's at Harvard, both in Physics.

		In cryptography, a Feistel cipher is a block cipher with a particular structure, named after IBM cryptographer Horst Feistel; it is also commonly known as a Feistel network.
		The Feistel structure has the advantage that encryption and decryption operations are very similar, even identical in some cases, requiring only a reversal of the key schedule.
		Feistel networks were first seen commercially in IBM's Lucifer cipher, designed by Feistel and Don Coppersmith.

		The second is an article written by Horst Feistel, a member of the IBM team that developed the Lucifer and DES ciphers.
		Led by Horst Feistel, the research group concluded its work in 1971 with the development of a cipher code-named Lucifer, which it promptly sold to Lloyd's of London for use in a cash-dispensing system that IBM had developed.

		Horst Feistel defined a variety of substitution and permutation primitives which are iteratively applied to data blocks for a specified number of times [3,4].
		Each set of primitive operations is called a "round," and the DES algorithm uses 16 rounds to ensure that the data are adequately scrambled to meet the security goals.

		Blowfish combines a Feistel network, key-dependent S-Boxes, and a non-invertible F function to create what is perhaps one of the most secure algorithms available.
		It was designed at IBM in the 1960s by Horst Feistel, of Feistel network fame.
		It uses a Feistel network (see the cryptography overview for details), but does not split the input evenly, instead dividing the 64 bit block into one 16 bit part and another 48 bit part.
