We present protocols for threshold cryptography in the GBD public-key cryptosystem. Both threshold decryption and threshold key generation are covered, in the “honest-butcurious” setting. This shows that it is possible to perform GBD computations in a distributed manner during both key generation and decryption, without revealing the private key to any party. GBD threshold decryption is similar...

BACKGROUND The aim of the present study was to evaluate the implication of male factor, in terms of sperm DNA oxidation and fragmentation, and Y chromosome microdeletions in recurrent spontaneous abortion (RSA) of unknown origin in a strictly selected cohort. METHODS A prospective cohort study was carried out in a private university-affiliated setting. Three groups, each comprised of 30 males...

Slow electrical activity was recorded from the dorsal hippocampus in rats during running in a motor-driven wheel, swimming, conditioned avoidance (running, jumping), lever pressing for food and sleep, and in cats during walking in a treadmill, eating and lapping milk. Large-amplitude clear rhythmical slow activity (RSA) was recorded from the hippocampus proper and smaller amplitude RSA and fast...

PURPOSE To evaluate the feasibility and accuracy of Roentgen stereophotogrammetric analysis (RSA) versus computed tomography (CT) for detecting stent-graft migration in an in vitro pulsatile circulation model and to study the feasibility of a nitinol endovascular clip (NEC) as an aortic wall reference marker for RSA. METHODS An aortic model with stent-graft was constructed and connected to an...

Conduct disorder (CD) and depression co-occur at far greater levels than chance, despite largely separate diagnostic criteria. One potential shared mechanism of this comorbidity is emotion dysregulation, which characterizes both internalizing and externalizing disorders. Previous research demonstrates that respiratory sinus arrhythmia (RSA)-a peripheral biomarker of emotion regulation-is attenu...

Feature Selection (FS) is a major preprocessing stage which aims to improve Machine Learning (ML) models’ performance by choosing salient features, while reducing the computational cost. Several approaches are presented select most Optimal Features Subset (OFS) in given dataset. In this paper, we introduce an FS-based approach named Reptile Search Algorithm–Snake Optimizer (RSA-SO) that employs...

The efficiency of decryption process of Multi prime RSA, in which the modulus contains more than two primes, can be speeded up using Chinese remainder theorem (CRT). On the other hand, to achieve the same level of security in terms integer factorization problem the length of RSA modulus must be larger than the traditional RSA case. In [9], authors studied the RSA public key cryptosystem in a sp...

This paper presents a unified architecture design of the RSA cryptosystem i.e. RSA cryptoaccelerator along with key-pair generation. A structural design methodology for the same is proposed and implemented. The purpose is to design a complete cryptosystem efficiently with reduced hardware redundancy. Individual modular architectures of RSA, Miller-Rabin Test and Extended Binary GCD algorithm ar...

We introduce Twin RSA, pairs of RSA moduli (n, n + 2), and formulate several questions related to it. Our main questions are: is Twin RSA secure, and what is it good for?

Recently, and contrary to the common belief, Rivest and Silverman argued that the use of strong primes is unnecessary in the RSA cryptosystem. This paper analyzes how valid this assertion is for RSA and its extensions to elliptic curves. Over elliptic curves, the analysis is more difficult because the underlying groups are not always cyclic. Previous papers suggested the use of strong primes in...
