Field programmable gate arrays (FPGAs) are an increasingly popular choice of platform for the implementation of cryptographic systems. For all such systems, random numbers are essential. One of the most well-known methods for producing true random number sequences in FPGAs is based on the phenomenon of jitter and built upon ring oscillators. This paper(More)
As the need of high quality random number generators is constantly increasing especially for cryptographic algorithms, the development of high throughput randomness generators has to be combined with the development of high performance statistical test suites. Unfortunately the implementations of the most popular batteries of test suites are not focused on(More)
Randomness comes in many flavours and has countless applications in various domains which state different quality requirements for the outcome of random number generators, therefore decisions on the suitability of a randomness generator for a specific application has to be made as a result of thorough analysis including the essential part of statistical(More)
Cryptographic applications need quality random number generators for reaching a high level of security. As the industry is moving forward at a high pace and the mobile paradigm emerging, new sources of randomness arise. One of them is the new generation of phones, also known as smartphones. We propose an unpredictable random number generator, which, using(More)
This paper presents a new method for creating TRNGs in Xilinx FPGAs. Due to its simplicity and ease of implementation, the design constitutes a valuable alternative to existing methods for creating single-chip TRNGs. Its main advantages are the high throughput, the portability and the low amount of resources it occupies inside the chip. Therefore, it could(More)
Random number sequences are of crucial importance in almost every aspect of modern digital cryptography, having a significant impact on the strength of cryptographic primitives in securing secret information by rendering it unknown, unguessable, unpredictable and irreproducible for an adversary. Although the major importance of high performance and high(More)
This paper presents the hardware implementation of the widely known NIST Statistical Test Suite – a battery of statistical tests for pseudorandom number generators (PRNGs) and true random number generators (TRNGs) – in a single Xilinx FPGA chip, using dynamic partial reconfiguration. The design offers a basic framework for easy integration(More)
— This paper focuses on the design and implementation of a high-quality and high-throughput true-random number generator (TRNG) in FPGA. Various practical issues which we encountered are highlighted and the influence of the various parameters on the functioning of the TRNG are discussed. We also propose a few values for the parameters which use the minimum(More)
Randomness test suites constitute an essential component within the process of assessing random number generators in view of determining their suitability for a specific application. Evaluating the randomness quality of random numbers sequences produced by a given generator is not an easy task considering that no finite set of statistical tests can assure(More)
The concept of Grid Computing addresses the next evolutionary step of distributed computing. Offering storage and computation capabilities to users not having those resources is the ultimate goal of grid computing. In this paper we introduce a taxonomy for grid applications, aiming at a better understanding of the categories of applications that could(More)
