Invariant Subspace Attack Against Midori64 and The Resistance Criteria for S-box Designs

Invariant Subspace Attack Against Midori64 and The Resistance Criteria for S-box Designs

We present an invariant subspace attack on the block cipher Midori64, proposed at Asiacrypt 2015. Our analysis shows that Midori64 has a class of 232 weak keys. Under any such key, the cipher can be distinguished with only a single chosen query, and the key can be recovered in 216 time with two chos...
