This paper presents single-chip FPGA Rijndael algorithm implementations of the Advanced Encryption Standard (AES) algorithm, Rijndael. In particular, the designs utilise look-up tables to implement the entire Rijndael Round function. A comparison is provided between these designs and similar existing implementations. Hardware implementations of encryption algorithms prove much faster than equiv...

A Look-Up Table (LUT) ring consists of memories, programmable interconnections and a control circuit. It sequentially emulates an LUT cascade representing a multipleoutput logic function. In this paper, we consider the realization of multi-output functions with LUT rings using large memories. In contrast to previous approaches where the number of inputs to each LUT cell is fixed, we allow the n...

Chamfer distances are discrete distances based on the propagation of local distances, or weights defined in a mask. The medial axis, i.e. the centers of the maximal disks (disks which are not contained in any other disk), is a powerful tool for shape representation and analysis. The extraction of maximal disks is performed in the general case with comparison tests involving look-up tables repre...

Pseudo random numbers are used in a number of areas such as cryptography and scientific and statistical simulation. Random numbers are crucial in statistics to obtain a uniform distribution for the prior knowledge and integration of Monte Carlo methods in statistical signal processing. In this paper, we propose a new random number generator using permutation matrices. This algorithm has three m...

The paper proposes the technology of control of integrity and legitimacy of information object usage with the Look Up Table-oriented (LUToriented) architecture. The technology is based on embedding the self-recovery digital watermark into information objects of such kind. The technology is the composition of approaches to forming the self-recovery digital watermarks in the passive multimedia co...

In this paper, we present the condition for the effective wire addition in Look-Up-Table-based (LUT-based) field programmable gate array (FPGA) circuits, and an optimization procedure utilizing the effective wire addition. Each wire has different characteristics, such as delay and power dissipation. Therefore, the replacement of one critical wire for the circuit performance with many non-critic...

This paper compares the original implementation of the trilateral filter with two proposed speed improvements. One is using simple look-up-tables, and leads to exactly the same results as the original filter. The other technique is using a novel way of truncating the look-up-table to a user specified required accuracy. Here, results differ from those of the original filter, but to a very minor ...

In this study, the authors present a novel data hiding scheme using the minimum distortion look-up table (LUT) embedding that achieves good distortion-robustness performance. LUT-based data hiding is a simple and efficient way to embed information into multimedia content for various applications, such as transaction tracking and database annotation. The authors find it possible to optimally red...

In this letter, we propose new driving methods for designing a driver independent of the current property of Organic Light Emitting Diodes (OLED) displays. The proposed methods are the Look-Up Table (LUT) and the Pulse Width Modulation (PWM). The LUT is used to handle the amount of the current for driving the OLED display panel and the PWM is applied to represent the gray scale on the OLED disp...
