		In cryptography, LOKI89 and LOKI91 are block ciphers designed as possible replacements for the Data Encryption Standard (DES).
		LOKI89 was first published in 1990, then named just "LOKI", by Austrialian cryptographers Lawrie Brown, Josef Pieprzyk and Jennifer Seberry.
		LOKI89 was submitted to the European RIPE project for evaluation, but was not selected.

		However unliketheir equivalents in the DES, they are intended to be as clean andsimple as possible (in retrospect perhaps a little too simple),aiding the analysis of the design.
		Following the publication of LOKI89, information on the newdifferential cryptanalysis became available, as well assome early analysis results by (Knudsen 1993a).This resulted in the design being changed to become LOKI91.
		The changes to thekey schedule were designed to reduce the number of "equivalent"or "related" keys, which resulted in the exhaustive search spacefor the cipher being reduced.

		The following are some notes on the LOKI89 and LOKI91 block ciphers, extracted from the lecture notes for my course in " Cryptography and Computer Security".
		LOKI is a cipher designed at ADFA as a result of the detailed analysis of existing block ciphers, particularly of the DES, and is the subject of Dr Brown's PhD

		It is a member of the LOKI family of ciphers, earlier instances being LOKI89 and LOKI91.
		The authors have stated that, "LOKI97 is a non-proprietary algorithm, available for royalty-free use worldwide as a possible replacement for the DES or other existing block ciphers." It was intended to be an evolution of the earlier LOKI89 and LOKI91 block ciphers.
		Please be aware that the key-length for this algorithm is 128, 192 or 256 Bits (16, 24 or 32 Characters).

		He acknowledged that the algorithm is inelegant and therefore hard to analyze, but nevertheless he claimed that HPC has good security.
		LOKI97 is a based on LOKI89 and LOKI91.
		It varies the Feistel structure in that, both before and after the round function is applied to half of the data block, key material is added to that half.

		In response to these attacks, LOKI’s designers went back to the drawing board and revised their algorithm.
		To make the algorithm more resistant to differential cryptanalysis and to remove the complementation property, the following changes were made to the original design:
		The attack is independent of the number of rounds of the algorithm.
