Secret image sharing technology is a strategy for jointly protecting secret images. The (n, n) problem can be solved by conventional Boolean calculation easily. However, how to recover images with progressive steps not addressed. In this study, we proposed an XOR-based (m, t, Ti) multi-secret scheme that shares m among participants and recovers shared progressively t thresholds. partition (SIPS...

The Bistable Ring (BR) Physical Unclonable Function (PUF) is a newly proposed hardware security primitive in the PUF family. In this work, we comprehensively evaluate its resilience against Machine Learning (ML) modeling attacks. Based on the success of ML attacks, we propose XOR strategies to enhance the security of BR PUFs. Our results show that the XOR BR PUF with more than four parallel BR ...

Symmetric key cryptography has been a hot topic because of exchange of secure communication through various networks ligand Investigation of reversible XOR like function for symmetric key cryptography has been a big challenge. Moreover it is also desired that the reversible XOR function must be as efficient as traditional XOR. In the literature related to Automatic Variables Key, Fibonacci-Q ma...

In this letter, we study the marginal density of the XOR distribution table, and the linear approximation table entries of regular substitution boxes (s-boxes). Based on this, we show that the fraction of good s-boxes (with regard to immunity against linear and differential cryptanalysis) increases dramatically with the number of input variables. Introduction Differential cryptanalysis [1], and...

The XOR-Ising model on a graph consists of random spin configurations on vertices of the graph obtained by taking the product at each vertex of the spins of two independent Ising models. In this paper, we explicitly relate loop configurations of the XOR-Ising model and those of a dimer model living on a decorated, bipartite version of the Ising graph. This result is proved for graphs embedded i...

A sinusoidal mask grating oriented orthogonally to and superimposed onto an optimally oriented base grating reduces a cortical neuron's response amplitude. The spatial selectivity of cross-orientation suppression (XOR) has been described, so for this paper we investigated the temporal properties of XOR. We recorded from single striate cortical neurons (n = 72) in anesthetized and paralyzed cats...

In this paper a new architecture for delay locked loops will be presented.  One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...

Overproduction of reactive oxygen species (ROS) by NADPH oxidase (NOX) and xanthine oxidoreductase (XOR) with a concomitant decrease in the bioavailability of nitric oxide (NO) from eNOS contributes to the development of cardiovascular and metabolic disorders. Extensive research has proven the existence of an alternative NOS-independent pathway for NO production. This nitrate-nitrite-NO pathway...
