Midori is a lightweight block cipher designed by Banik et al. at ASIACRYPT 2015. One version of Midori uses a 64-bit state, another uses a 128-bit state and we denote these versions Midori-64 and Midori128. Each of these versions uses a 128-bit key. In this paper, we focus on the key-recovery attacks on reduced-round Midori-64 with meet-in-themiddle method. We use the differential enumeration t...

Midori is a light weight block cipher recently presented by Banik et al in ASIACRYPT 2015. There are two versions of Midori with state sizes of 64-bit and 128-bit respectively. The round function is based on Substitution-Permutation Network(SPN). In this paper, we give impossible differential cryptanalysis of Midori64. We studied the non-linear layer of the cipher and give two useful properties...

Mitochondrial-encoded genes are increasingly targeted in studies using high-throughput sequencing approaches for characterizing metazoan communities from environmental samples (e.g., plankton, meiofauna, filtered water). Yet, unlike nuclear ribosomal RNA markers, there is to date no high-quality reference dataset available for taxonomic assignments. Here, we retrieved all metazoan mitochondrial...
