State Complexity of Multiple Catenations

open access: yesFundamenta Informaticae, 2018
We improve some results relative to the state complexity of the multiple catenations described by Gao and Yu. In particular we nearly divide by 2 the size of the alphabet needed for witnesses. We also give some refinements to the algebraic expression of the state complexity, which is especially complex with this operation.

The multiplicative complexity of interval checking

open access: yesIACR Cryptol. ePrint Arch., 2022
We determine the exact AND-gate cost of checking if $a\leq x < b$, where $a$ and $b$ are constant integers. Perhaps surprisingly, we find that the cost of interval checking never exceeds that of a single comparison and, in some cases, it is even lower.

A Tool for Lightweight (AND, XOR) Implementations of Large-Degree S-boxes

open access: yesTransactions on Cryptographic Hardware and Embedded Systems
We propose a new ad hoc automatic tool to look for lightweight implementations of non-linear functions on up to 7 variables. This tool is mainly aimed at finding implementations of arbitrary cryptographic S-boxes, with the goal of enabling lightweight ...

The multiplicative complexity of discrete cosine transforms

open access: yes, 1992
We obtain the multiplicative complexity of discrete cosine transforms in all cases. It is given as a function of the multiplicative complexity of discrete Fourier transforms.

UnifiedFace: A Uniform Margin Loss Function for Face Recognition

open access: yesApplied Sciences, 2023
Face recognition has achieved great success due to the development of deep convolutional neural networks (DCNNs) and loss functions based on margin. However, complex DCNNs bring a large number of parameters as well as computational effort, which pose a ...

Concrete Multiplicative Complexity of Symmetric Functions

open access: yes, 2006
The multiplicative complexity of a Boolean function f is defined as the minimum number of binary conjunction (AND) gates required to construct a circuit representing f, when only exclusive-or, conjunction and negation gates may be used.
