The huge time and memory complexities of utilizing bitbased division property, which was first presented by Todo and Morri at FSE 2016, bothered cryptographers for quite some time and it had been solved by Xiang et al. at ASIACRYPT 2016. They applied MILP method to search integral distinguisher based on division property, and used it to analyze six lightweight block ciphers. Later on, Sun et al...

Abstract. An increasing number of cryptographic primitives are built using the ARX operations: addition modulo 2, bit rotation and XOR. Because of their very fast performance in software, ARX ciphers are becoming increasingly common. However, there is currently no rigorous understanding of the security of ARX ciphers against one of the most common attacks in symmetric-key cryptography: differen...

The power unit on board the ship generates periodic low-frequency vibration that affects normal operation of equipment board, and adaptive feedforward control algorithm can effectively suppress such harmful noise. But needs to obtain identification model secondary channels, frequency domain least squares method based linear Extended auto-regressive (ARX) is difficult with nonlinear characterist...

The application of optimization methods to prediction issues is a continually exploring field. In line with this, this paper investigates the connectedness between infected cases COVID-19 and US fear index from forecasting perspective. complex characteristics implied volatility risk such as non-linearity structure, time-varying non-stationarity motivate us apply nonlinear polynomial Hammerstein...

Kurau River Basin (KRB), which covers an area of 322 km2 and is the main drainage artery pouring into Bukit Merah Reservoir (BMR), located in Perak State Malaysia. The study rainfall-runoff processes KRB important because BMR plays a vital role rice production, flood control, ecosystems, tourism region. This proposes new approach to modeling based on fractional calculus. A dataset daily rainfal...

The probably approximately correct (PAC) learning theory was originally introduced to address static models where the input data were assumed to be i.i.d. In many real applications; however, datasets and systems to be modeled are often dynamic. This encourages the efforts to extend the conventional PAC learning theory to address typical dynamic models such as finite impulse response (FIR) and a...

In recent years, encrypted databases have emerged as a promising direction that provides data confidentiality without sacrificing functionality: queries are executed on encrypted data. However, existing practical proposals rely on a set of weak encryption schemes that have been shown to leak sensitive data. In this paper, we propose Arx, the first practical and functionally rich database system...

This paper presents a mathematical model of an inventory system from the warehouse of goods Distribution Company using system identification approach. Considering items ordered from suppliers and items shipped to customers, as the inputs of the system and the stock level as the output system. In this paper, ARX model and ARMAX model are outlined and compared. The performances of each type of mo...

BACKGROUND A model-based controller for an artificial beta cell requires an accurate model of the glucose-insulin dynamics in type 1 diabetes subjects. To ensure the robustness of the controller for changing conditions (e.g., changes in insulin sensitivity due to illnesses, changes in exercise habits, or changes in stress levels), the model should be able to adapt to the new conditions by means...
