Block Cipher Invariants as Eigenvectors of Correlation Matrices
Tim Beyne
Abstract
A new approach to invariant subspaces and nonlinear invariants is developed. This results in both theoretical insights and practical attacks on block ciphers. It is shown that, with minor modifications to some of the round constants, Midori-64 has a nonlinear invariant with
