In CHES 2017, Moradi et al. presented a paper on ``Bit-Sliding'' in which the authors proposed lightweight constructions for SPN based block ciphers like AES, Present and SKINNY. The main idea behind ...
Constructing TI-friendly Substitution Boxes using Shift-Invariant Permutations
Shift-invariant Threshold implementation Sbox
2018/11/7
The threat posed by side channels requires ciphers that can be efficiently protected in both software and hardware against such attacks. In this paper, we proposed a novel Sbox construction based on i...
Hidden Shift Quantum Cryptanalysis and Implications
quantum cryptanalysis hidden shift problem Simon-meets- Kuperberg
2018/5/15
First, we have developped new algorithms that improve and generalize Kuperberg’s algorithm for the hidden shift problem, which is the algorithm that applies instead of Simon when considering modular a...
We give the first information-theoretic security proof of the `Round Robin Differential Phase Shift' Quantum Key Distribution scheme. Our proof consists of the following steps. We construct an EPR var...
Round-Robin Differential Phase-Shift (RRDPS) is a Quantum Key Distribution (QKD) scheme proposed by Sasaki, Yamamoto and Koashi in 2014. It works with high-dimensional quantum digits (qudits). Its mai...
A SAT-Based Algorithm for Finding Short Cycles in Shift Register Based Stream Ciphers
stream cipher Trivium Grain
2016/12/7
This paper addresses the problem of finding short cycles in the internal state space of shift register based stream ciphers. The absence of short cycles is a desirable property for stream ciphers beca...
The Adjacency Graphs of Linear Feedback Shift Registers with Primitive-like Characteristic Polynomials

2016/3/11
We consider the adjacency graphs of the linear feedback shift registers (LFSRs) with characteristic polynomials of the form l(x)p(x), where l(x) is a polynomial of small degree and p(x) is a primitive...
An Equivalence-Preserving Transformation of Shift Registers
Feedback shift register NLFSR Fibonacci configuration
2016/1/26
The Fibonacci-to-Galois transformation is useful for reducing the propagation
delay of feedback shift register-based stream ciphers and hash functions.
In this paper, we extend it to handle Galois-t...
The Adjacency Graphs of Some Feedback Shift Registers

2016/1/7
The adjacency graphs of feedback shift registers (FSRs) with characteristic function of the
form g = (x0+x1)∗f are considered in this paper. Some properties about these FSRs are given.
It is p...

2016/1/3
The Linearization of Nonlinear feedback shift registers (NFSRs) is to find their state transition matrices. In this paper,
we investigate the linearization multi-valued NFSRs by considering it as a l...

In this paper, we consider the cycle structures of feedback shift registers (FSRs).
At the beginning, the cycle structures of two special classes of FSRs, pure circulating
registers (PCRs) and pure ...

We continue the research of Jansen et al. (IEEE Trans on Information Theory 1991)
to construct De Bruijn sequences from feedback shift registers (FSRs) that contain
only very short cycles. Firstly, ...

2015/12/21
We consider the symmetric Feedback Shift Registers (FSRs), especially a special class of
symmetric FSRs (we call them scattered symmetric FSRs), and construct a large class of De
Bruijn sequences fr...

2014/3/10
Nonlinear feedback shift registers (NLFSRs) are used to construct pseudorandom generators for stream ciphers. Their theory is not so complete as that of linear feedback shift registers (LFSRs). In gen...
