A Survey of ARX-based Symmetric-key Primitives [PDF]

, 2022
Addition Rotation XOR is suitable for fast implementation symmetric –key primitives, such as stream and block ciphers. This paper presents a review of several block and stream ciphers based on ARX construction followed by the discussion on the security ...

Rotational Cryptanalysis on ChaCha Stream Cipher [PDF]

, 2022
In this paper we consider the ChaCha20 stream cipher in the related-key scenario and we study how to obtain rotational-XOR pairs with nonzero probability after the application of the first quarter round.

Rotational-XOR Cryptanalysis of Simon-like Block Ciphers [PDF]

, 2020
Rotational-XOR cryptanalysis is a cryptanalytic method aimed at finding distinguishable statistical properties in ARX-C ciphers, i.e., ciphers that can be described only using modular addition, cyclic rotation, XOR, and the injection of constants.

Localizing Noncooperative Receiver Through Full-Duplex Amplify-and-Forward Relay

IEEE Access, 2018
Localizing noncooperative transmitter (Tx) and receiver (Rx) that belong to another system is important in many scenarios, e.g., interference management in cognitive radio systems and user behavior learning in ad hoc wireless networks. However, obtaining

A study about signal variation with minor receiver displacement in a meeting room at 60 GHz: measurements and simulations

EURASIP Journal on Wireless Communications and Networking, 2021
The aim of this work is to study the impact of small receiver displacement on a signal propagation in a typical conference room environment at a millimeter wave frequency of 60 GHz. While channel measurements provide insights on the propagation phenomena,

Prediction Method for Propagation Path Loss Obstructed by Dielectric Material in the 920-MHz Band

IEEE Access, 2023
This paper presents a simple calculation method for predicting the propagation path loss of a radio wave passing through a dielectric obstruction between a transmitter (Tx) and receiver (Rx). In this paper, the propagation characteristics of a radio that

Rotational-XOR Cryptanalysis of Reduced-round SPECK

IACR Transactions on Symmetric Cryptology, 2017
In this paper we formulate a SAT/SMT model for Rotational-XOR (RX) cryptanalysis in ARX primitives for the first time. The model is successfully applied to the block cipher family Speck, and distinguishers covering more rounds than previously are found ...
