Improvement on bit diffusion analysis of $\pi$-cipher

Rok, strany: 2017, 139 - 149

$\pi$-Cipher, designed by {Gligoroski} et al., is a second round candidate of the {CAESAR} competition. The designers analyzed the bit diffusion of the cipher by examining the $\ast$~operation and 1 round $\pi$-function. We improve this analysis by applying Strict Avalanche Criterion (SAC) test to $\ast$ operation and reduced round versions of $\pi$-function for $\pi\,16$-Cipher. We found out that $\ast$ operation fails SAC test whereas all versions of $\pi$-function for $\pi\,16$-Cipher pass the test.
