At Indocrypt 2016, Ashur et al. showed that linear hulls are sometimes formed in a single round of a cipher (exemplifying on Simon ciphers) and showed that the success rate of an attack may be influen...
The block cipher Simon has a very simple round function.
This simplicity allows us to compute the correlation matrix of the round
function. Despite its simplicity, Simon exhibits some very interesti...

In this paper we investigate the linear hull effect in the light-weight block cipher EPCBC. We give an efficient method of computing linear hulls with high capacity. We then apply found hulls to deriv...
