We show that there is a very straightforward closed algebraic formula for the Rijndael block cipher. This formula is highly structured and far simpler then algebraic formulations o...
This paper proposes a new way of efficiently doing arbitrary ¢ -bit permutations in programmable processors modeled on the theory of omega and flip networks. The new omflip ins...
This paper proposed a novel method to protect logging information more securely. The method, named NIGELOG, produces multiple backups of the logging information, hides them in arb...
