摘要： A system for performing real-time quantum-safe computation of a digital transaction using in a blockchain consensus protocol, comprising a plurality of permissioned verification servers being a plurality of distributed participants that are adapted to create common randomization to all of said participants which remains unrevealed until being used by said participants, by assigning to each participant a unique polynomial having a maximal degree being common to all participants; allowing each participant to select a random value; allowing each participant to send his selected random value to all other participants using a secret sharing scheme based on points on his unique polynomial, such that said secret hides the details of said selected random value and all other participants that receive shares of said selected random value will not be able to reconstruct said selected random value from the received shares; create a pool of all shares of all participants; build a quantum-safe consensus of honest participants, in rounds, by sharing symmetric keys beyween participants before a consensus round and recovering said keys after each consensus round; during each round, generate common random coins for which a consensus has been obtained, from shares belonging to at least one honest participant in said round, and locking new created coins by a quantum-safe asynchronous Byzantine Fault Tolerance (a BFT)-based blockchain consensus protocol, while the consensus itself provides the consensus ability on transactions in Block(s) for said a BFT protocol; at the end of each round, validate said transaction using the locked common random coin and revealing the secret to all participants.

摘要： A system for prompt virus infection carriers detection/screening using THz spectroscopy, which comprises a micro/nano-antennas array implemented as an antenna chip of predetermined shape and size, that has the maximum aspect ratio of the capacitor gap being sensitive to both P and S polarization, the array consisting of a plurality of printed micro-antenna elements, each of which having an equivalent inductor L of printed inductors and an equivalent capacitor C defined by gaps between printed contacts the length of the capacitor and the dielectric constant of a filler being between the printed contacts, to thereby determine a resonant frequency of the antenna element, the gaps are formed essentially along the cross diagonals of the each antenna element, thereby obtaining maximal aspect-ratio between the length of the capacitor and the gap width, that maximizes and sharpen the resonance effect of the each micro-antenna element; at least one capsule for holding the chip with the antennas array in a fixed position, preferably at the center, the at least one capsule being at least partially transparent to THz radiation range; means for applying material containing samples of viruses/exhaled biological ingredients to be detected that are exhaled into the gaps, for altering the dielectric constant of the filler and the resonance frequency; a THz spectrometer for scanning the samples and detecting shifts in the resonance frequency induced by the presence of the exhaled viruses/biological ingredients; at least one processor for processing the detected shifts in the resonance frequency and associating different shifts with different types of viruses/biological ingredients. The size of the array is matched to the beam size of the spectrometer, such that the entire radiation collimated beam will be captured by the antennas array, thereby maximizing the signal to noise ratio and the dynamic range.
