Differential Analysis on Block Cipher PRIDE
نویسندگان
چکیده
The lightweight block cipher PRIDE designed by Albrecht et al., appears in CRYPTO 2014. The designers claim that their method of constructing linear layer is good both in security and efficiency. In this paper, we find 16 different 2-round iterative characteristics utilizing the weaknesses of S-box and linear layer, construct several 15-round differentials. Based on one of the differentials, we launch differential attack on 18-round PRIDE. The data, time and memory complexity are 2, 2 and 2, respectively.

Improved Differential Analysis of Block Cipher PRIDE
In CRYPTO 2014 Albrecht et al. brought in a 20-round iterative lightweight block cipher PRIDE which is based on a good linear layer for achieving a tradeoff between security and efficiency. A recent analysis is presented by Zhao et al.. Inspired by their work, we use an automatic search method to find out 56 iterative differential characteristics of PRIDE, containing 24 1-round iterative charac...
متن کاملA First DFA on PRIDE: from Theory to Practice (extended version)
Abstract. PRIDE is one of the most efficient lightweight block cipher proposed so far for connected objects with high performance and lowresource constraints. In this paper we describe the first ever complete Differential Fault Analysis against PRIDE. We describe how fault attacks can be used against implementations of PRIDE to recover the entire encryption key. Our attack has been validated fi...
متن کاملDifferential Attacks on Lightweight Block Ciphers PRESENT, PRIDE, and RECTANGLE Revisited
Differential distribution and linear approximation tables are the main security criteria for S-box designers. However, there are other S-box properties that, if overlooked by cryptanalysts, can result in erroneous results in theoretical attacks. In this paper we focus on two such properties, namely undisturbed bits and differential factors. We go on to identify several inconsistencies in publis...
متن کاملDifferential Cryptanalysis of 18-Round PRIDE
The rapid growth of the Internet of Things together with the increasing popularity of connected objects have created a need for secure, efficient and lightweight ciphers. Among the multitude of candidates, the block cipher PRIDE is, to this day, one of the most efficient solutions for 8-bit micro-controllers. In this paper, we provide new insights and a better understanding of differential atta...
متن کاملImpossible 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...
