Volume 11, Issue 1 , Winter and Spring 2019, , Pages 57-74

http://dx.doi.org/10.22042/isecure.2018.138036.420

Abstract
  In the biclique attack, a shorter biclique usually results in less data complexity, but at the expense of more computational complexity. The early abort technique can be used in partial matching part of the biclique attack in order to slightly reduce the computations. In this paper, we make use of this ...  Read More

Abstract
  Impossible differential attack is a well-known mean to examine robustness of block ciphers. Using impossible differential cryptanalysis, we analyze security of a family of lightweight block ciphers, named Midori, that are designed considering low energy consumption. Midori state size can be ...  Read More

http://dx.doi.org/10.22042/isecure.2016.8.1.2

Abstract
  In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. ...  Read More

15. Total break of Zorro using linear and differential attacks

Sh. Rasoolzadeh; Z. Ahmadian; M. Salmasizadeh; M. R. Aref

Volume 6, Issue 1 , Winter and Spring 2014, , Pages 23-34

http://dx.doi.org/10.22042/isecure.2014.6.1.3

Abstract
  An AES-like lightweight block cipher, namely Zorro, was proposed in CHES 2013. While it has a 16-byte state, it uses only 4 S-Boxes per round. This weak nonlinearity was widely criticized, insofar as it has been directly exploited in all the attacks on Zorro reported by now, including the weak key, reduced ...  Read More
