K.: Generalized oblivious transfer protocols based on noisy channels

Abstract. The main cryptographic primitives (Bit Commitment (BC) and Oblivious Transfer (OT) protocols) based on noisy channels have been considered in [1] for asymptotic case. Non-asymptotic behavior of BC protocol has been demonstrated in [2]. The current paper provides stricter asymptotic conditions on Binary Symmetric Channel (BSC) to be feasible OT protocol proposed in [1]. We also generalize this protocol using different encoding and decoding methods that require to regain formulas for Renyi entropy. Nonasymptotic case (finite length of blocks transmitted between parties) is also presented. Some examples are given to demonstrate that these protocols are in fact reliable and information-theoretically secure. We also discuss the problem – how to extend ( 2)-OT protocol to ( L)-OT protocol and how to arrange BSC 1 1 connecting parties. Both BC and OT protocols can be used as components of more complex and more important for practice protocols like “Digital cash”, “Secure election ” or “Distance bounding”.

Interaction of 5-bromоmethylfurfural with Silver Fluoride in Methanol and Toluene

При взаимодействии 5-бромметилфурфурола и фторида серебра (I) в безводном толуоле и водно-метанольной среде при 25ºС образуется новое соединение, 5-фторметилфурфурол - продукт нуклеофильного замещения атома галогена. Его выход в водно-метанольной среде составляет 1-3 %, а в безводном толуоле - до 10 %. В качестве основных продуктов реакции образуются продукты алкилирования толуола и 5-гидроксиметилфурфурола метиленфурфурол-катионом.The action of silver (I) fluoride on the 5-bromоmethyfurfural leads to a new compound, 5-fluoromethylfurfural, as a product of nucleophilic substitution. Yields of 5-fluoromethylfurfural attain 10 % and 1-3 % in anhydrous toluene and water-methanol medium, respectively. Main products of the reaction are the products of toluene and 5-hydroxymethylfurural alkylation by methylenfurfuryl cation

Hyperon signatures in the PANDA experiment at FAIR

We present a detailed simulation study of the signatures from the sequential decays of the triple-strange pbar p -> Ω+Ω- -> K+ΛbarK- Λ -> K+pbarπ+K-pπ- process in the PANDA central tracking system with focus on hit patterns and precise time measurement. We present a systematic approach for studying physics channels at the detector level and develop input criteria for tracking algorithms and trigger lines. Finally, we study the beam momentum dependence on the reconstruction efficiency for the PANDA detector

Pseudorapidity densities of charged particles with transverse momentum thresholds in pp collisions at √ s = 5.02 and 13 TeV

The pseudorapidity density of charged particles with minimum transverse momentum (pT) thresholds of 0.15, 0.5, 1, and 2 GeV/c is measured in pp collisions at the center of mass energies of √s=5.02 and 13 TeV with the ALICE detector. The study is carried out for inelastic collisions with at least one primary charged particle having a pseudorapidity (η) within 0.8pT larger than the corresponding threshold. In addition, measurements without pT-thresholds are performed for inelastic and nonsingle-diffractive events as well as for inelastic events with at least one charged particle having |η|2GeV/c), highlighting the importance of such measurements for tuning event generators. The new measurements agree within uncertainties with results from the ATLAS and CMS experiments obtained at √s=13TeV.
