چکیده

Khudra is a 18-round lightweight block cipher proposed by Souvik Kolay and Debdeep Mukhopadhyay in the SPACE 2014 conference which is applicable to Field Programmable Gate Arrays (FPGAs). In this paper, we obtain 2 14-round related-key impossible differentials of Khudra, and based on these related-key impossible differentials for 32 related keys, we launch an attack on the full Khudra with data complexity of 2 related-key chosen-plaintexts, time complexity of about 2 encryptions and memory complexity of 2.

Related-Key Rectangle Attack on Round-reduced Khudra Block Cipher

Khudra is a block cipher proposed in the SPACE’2014 conference, whose main design goal is to achieve suitability for the increasingly popular Field Programmable Gate Array (FPGA) implementation. It is an 18-round lightweight cipher based on recursive Feistel structure, with a 64-bit block size and 80-bit key size. In this paper, we compute the minimum number of active F -functions in differenti...

Impossible Differential Cryptanalysis on Deoxys-BC-256

Deoxys is a final-round candidate of the CAESAR competition. Deoxys is built upon an internal tweakable block cipher Deoxys-BC, where in addition to the plaintext and key, it takes an extra non-secret input called a tweak. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal tweakable block cipher. First, we find a 4.5-round...

A Guess-and-Determine Attack on Reduced-Round Khudra and Weak Keys of Full Cipher

Khudra is a lightweight block cipher designed for Field Programmable Gate Array (FPGA) based platforms. The cipher has an 18-round generalized type-2 Feistel structure with 64-bit block size. The key schedule takes 80-bit master key and produces 32-bit round keys performing very simple operations. In this work, we analyze the security of Khudra. We first show that the effective round key length...

A new method for accelerating impossible differential cryptanalysis and its application on LBlock

Impossible differential cryptanalysis, the extension of differential cryptanalysis, is one of the most efficient attacks against block ciphers. This cryptanalysis method has been applied to most of the block ciphers and has shown significant results. Using structures, key schedule considerations, early abort, and pre-computation are some common methods to reduce complexities of this attack. In ...

Impossible Differential Cryptanalysis of Reduced-Round Midori64 Block Cipher (Extended Version)

Impossible differential attack is a well-known mean to examine robustness of block ciphers. Using impossible differ- ential 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 either 64 bits for Midori64 or 128 bits for Midori128; however, both vers...
