Recently, a lot of progresses have been made in software implementations of pairings at the 128-bit security level in large characteristic. In this work, we obtain analogous progresses for hardware implementations. For this, we use the RNS representation of numbers which is especially well suited for pairing computation in a hardware context. A FPGA implementation is proposed, based on an adapt...

Residue scaling is needed in pipelined FFT radix-4 processors based on the Modified Quadratic Residue Number System (MQRNS) at the output of each butterfly. Such processor uses serial connection of radix-4 butterflies. Each butterfly comprises n subunits, one for each modulus of the RNS base and generates four complex residue numbers. In order to prevent the arithmetic overflow in the succesive...

In this paper, a residue number arithmetic is used in direct sequence spread spectrum system, this system is evaluated and the bit error probability of this system is compared to that of non residue number system. The effect of channel bandwidth, PN sequences, multipath effect and modulation scheme are studied. A Matlab program is developed to measure the signal-to-noise ratio (SNR), and the bi...

A special moduli set Residue Number System (RNS) of high dynamic range (DR) can speed up the execution of very large word-length repetitive multiplications found in applications like public key cryptography. The modulo 2 − 1 multiplier is usually the noncritical datapath among all modulo multipliers in such high-DR RNS multiplier. This timing slack can be exploited to reduce the system area and...

In this paper, architecture of residue number system used in FIR filters, is presented. For many years residue number coding has been recognized as a system which provides capability for implementation of a high speed addition and multiplication. These advantages of residue number system coding for the high speed FIR filters design results from the fact that an digital FIR filter requires only ...

The residue number system is an integer number system and is inconvenient to represent numbers with fractional parts. In the symmetric residue system, a new representation of floating-point numbers and arithmetic algorithms for its addition, subtraction, multiplication, and division are proposed. A floating-point number is expressed as an integer multiplied by a product of the moduli. The propo...

Residue Number System (RNS) has computational advantages for large integer arithmetic. It provides the benefits of parallel, carry-free, and high-speed arithmetic in addition, subtraction, and multiplication. However, overflow detection, sign detection, magnitude detection, and division are time-consuming operations in RNS. The most interesting one of the above operations is division, and many ...

Because the t-out-of-n oblivious transfer (OT) protocol can guarantee the privacy of both participants, i.e., the sender and the receiver, it has been used extensively in the study of cryptography. Recently, Chang and Lee presented a robust t-out-of-n OT protocol based on the Chinese remainder theorem (CRT). In this paper, we use the Aryabhata remainder theorem (ART) to achieve the functionalit...

Use of neural networks for computer vision, speech recognition, and other applications has exploded in recent years, in part due to their unprecedented performance on a variety of benchmarks. Nonetheless, highthroughput and energy-efficient evaluation of such neural networks, and in particular, convolutional neural networks (CNNs), remains an active field of research. Evaluation of networks is ...
