Security analysis of an encryption scheme based on nonpositional polynomial notations
Open Engineering, 2016 The aim of the research was to conduct a cryptographic analysis of an encryption scheme developed on the basis of nonpositional polynomial notations to estimate the algorithm strength. Nonpositional polynomial notations (NPNs) are residue number systems (

DAIMI Report Series, 1993 In this paper we examine the redesign of LOKI, LOKI91 proposed by Brown et al. First it is shown that there is no characteristic with a probability high enough to do a successful differential attack on LOKI91. Secondly we show that the size of the image of the F-function in LOKI91 is 8\22*2^32.

Subspace Trail Cryptanalysis and its Applications to AES
IACR Transactions on Symmetric Cryptology, 2017 We introduce subspace trail cryptanalysis, a generalization of invariant subspace cryptanalysis. With this more generic treatment of subspaces we do no longer rely on specific choices of round constants or subkeys, and the resulting method is as such a ...

Lightweight Encryption for Raw‐Format Live Video Streaming Over Automotive Ethernet
Electronics Letters, Volume 61, Issue 1, January/December 2025.The proposed lightweight encryption scheme is implemented using GStreamer pipeline elements to provide secure raw‐format live video streaming over automotive Ethernet. In order to derive an optimal trade‐off between encryption robustness and low CPU overhead under limited CPU resources, the confidentiality of the proposed scheme is evaluated through ...

Quantifying Shannon's Work Function for Cryptanalytic Attacks
, 2010 Attacks on cryptographic systems are limited by the available computational resources. A theoretical understanding of these resource limitations is needed to evaluate the security of cryptographic primitives and procedures.

Cryptanalysis of Round-Reduced Fantomas, Robin and iSCREAM
Cryptography, 2019 In this work, we focus on LS-design ciphers Fantomas, Robin, and iSCREAM. LS-designs are a family of bitslice ciphers aimed at efficient masked implementations against side-channel analysis.
