Single-bit processor for lightweight galois field calculation
(Видавництво Львівської політехніки, 2013) Dobush, Andrij; Kostyk, Andrij
Lightweight cryptography is a branch of the modern cryptography, which covers cryptographic algorithms intended for use in devices with low or extremely low resources. Lightweight cryptography does not determine strict criteria for classifying a cryptographic algorithm as lightweight, but the common features of lightweight algorithms are extremely low requirements to essential resources of target devices.

Authenticity of digital images
(Видавництво Львівської політехніки, 2013) Hanzlik, Lucjan; Wodo, Wojciech
Copyrights are a big issue these days, it is extremely easy to loose our intellectual property (in sense of digital images) and thus money, moreover it is hard to proof our rights in the court. Our digital pictures must be protected in such a manner that it should be easy to proof we are the legitimate owner of the image and it should be computationally hard to forge such proof. We present a sketch of a new solution for copyright protection of digital images using chameleon hash functions, signatures and steganography. It is an extension of previous work in this field. We introduce a probabilistic similarity method into our scheme, which convince the verifier at certain level about the owner of the picture.
System for enhancing the security of private data using public-key cryptography
(Видавництво Львівської політехніки, 2013) Kostyshyn, Danylo; Levus, Yevheniya
This article describes the client-server system for asymmetric-keys encryption of users private correspondence in one of the most popular social network - Facebook. The system uses browser extension as a client, asymmetric-keys algorithm to implement an encryption and the server in turn serves as a public-keys distribution center for users. The system resolves three basic principles of information security - confidentiality, integrity and availability.
Higher order spectra analysis for assessing stationarity
(Видавництво Львівської політехніки, 2013) Stavorovsky, Konstantin; Popov, Anton
In this paper the new approach to investigation of signals stationarity based on parameters of bispectrum is proposed. The method was examined using simulated test signals artificially test signals with predefined nonstationarities. As test signals Gaussian noise with varying variance and mean value were proposed. Proposed bispectral characteristics are different for stationary and nonstationary signals.

Irradiation-resistant magnetic field microsensors
(Видавництво Львівської політехніки, 2013) Bolshakova, Inessa; Yerashok, Volodymyr; Zagachevskyi, Yuriy; Makido, Olena; Tymoshyn, Serhiy; Stetsko, Roman; Kokoten, Nazar; Prykhodko, Oleksandr; Shurygin, Fedir
A technology developed for creating radiationresistant magnetic field sensors based on semiconductor binary compounds of III-V group (InSb, InAs, GaAs) and their solid solutions (InXGa1-XAs, InAsXIn1-X) is presented. Studies have confirmed such sensors’ operability in neutron fluxes up to high fluences. This has made possible their use in magnetic measuring instrumentation for magnetic field diagnostics in thermonuclear reactors. The instrumentation comprises a 3D probe with Hall sensors and electronics characterized by the function of in-situ self-calibration, which makes available periodic calibration of sensors without their reinstallation, leading to high measurement accuracy. The magnetic measuring instrumentation developed by the team has been applied in European reactors TORE SUPRA (France) and JET (UK), and is aimed at solving tasks at a new charged particle accelerator – collider NICA (Russia).
