BORON is a 64-bit lightweight block cipher based on the substitution–permutation network
that supports an 80-bit (BORON-80) and 128-bit (BORON-128) secret key. In this paper, we …

In this letter, we present a meet-in-the-middle attack on the 7-round reduced block cipher
Kalyna-b/2b, which has been approved as the new encryption standard of Ukraine (DSTU …

Midori64 and Midori128 2 are lightweight block ciphers, which respectively cipher 64-bit and
128-bit blocks. While several attack models are discussed by the authors of Midori, the …

LBlock is a 32-round lightweight block cipher with a 64-bit block size and an 80-bit key. This
paper presents a new impossible differential attack on LBlock by improving the previous …

We propose a new 64-bit blockcipher Piccolo supporting 80 and 128-bit keys. Adopting
several novel design and implementation techniques, Piccolo achieves both high security …

Biclique cryptanalysis is an attack which reduces the computational complexity by finding a
biclique which is a kind of bipartite graph. We show a single‐key full‐round attack of the …

The paper expounds the progress made in the block cipher analysis techniques and
summarizes the current situation of the block cipher analysis at home and abroad …

The development of ARX-based lightweight block ciphers has been plagued by the difficulty
of theoretical security analysis. SAND solves this problem better by obtaining an equivalent …

Midori is a hardware-oriented lightweight block cipher designed by Banik\emph {et al.} in
ASIACRYPT 2015. It has two versions according to the state sizes, ie Midori64 and …

LBlock is a new lightweight block cipher proposed by Wu and Zhang (2011)[12] at ACNS
2011. It is based on a modified 32-round Feistel structure. It uses keys of length 80 bits and …
