Algebraic Cryptanalysis of Variants of Frit [PDF]

open access: possible, 2020
Frit is a cryptographic 384-bit permutation recently proposed by Simon et al. and follows a novel design approach for built-in countermeasures against fault attacks. We analyze the cryptanalytic security of Frit in different use cases and propose attacks on the full-round primitive.

Algebraic Cryptanalysis of A NLFSR Based Stream Cipher [PDF]

open access: possible2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications, 2008
Among recent developments on stream ciphers, the algebraic attack has gained much attention. In this paper we concentrate on algebraic cryptanalysis of Grain, a non-linear feedback shift register (NLFSR) based stream cipher. The target here is to analyze generic key generating structure of Grain, that is why, we aim to recover the internal states of ...

Cryptanalysis via Algebraic Spans

2018
We introduce a method for obtaining provable polynomial time solutions of problems in nonabelian algebraic cryptography. This method is widely applicable, easier to apply, and more efficient than earlier methods. After demonstrating its applicability to the major classic nonabelian protocols, we use this method to cryptanalyze the Triple Decomposition ...

Algebraic Cryptanalysis and RFID Authentication

2015
The standardization group ISO/IEC SC31/WG7 is working on a set of cryptographic suites to provide security to wireless devices including UHF RFID tags. These cryptographic suites are presented as independent parts to a single standard ISO/IEC 29167. Within this multi-part standard 29167-15 is based around very simple operations and intended to provide ...
