    Micro-service support by module architecture application of the service platform for OSGI Java additions
    (Видавництво Львівської політехніки, 2020-02-24) Mamro, Oleksandr; Lagun, Andrii; Lviv Polytechnic National University
    This article analyzes the problems of creating and maintaining the micro-service-oriented architecture. The solution of the OSGI modular architecture and its alternatives was also considered, as well as the strength and weakness, were identified. The practical part is to create an OSGI system for IoT (wireless network access), which uses a sensor system and a data processing system, with a centralized modular system for processing input data from different devices. The modules are broken down into data processing functionality. The complexity of refactoring micro-service architecture using OSGI modules was also investigated.

    Using Improved Homophonic Encryption on the Example of Code Zodiac Z408 to Transfer Encrypted Information Based on Data Traffic
    (Lviv Politechnic Publishing House, 2021-03-01) Mamro, Oleksandr; Lagun, Andrii; Lviv Polytechnic National University
    This article examines the improvement of homophonic encryption using the well-known Z408 cipher as an example, and analyzes their problems to further correct the main shortcomings of this typea of encryption. In the practical part, an encryption system similar to Z408 was created and the complexity ofthe language analysis for this cipher was increased. The correlation dat of the number of alternative characters was used to improve the transmission of encrypted data depending on the load of the device. The more symbols and the higher the load, the fewer the number of alternative symbols will be used.
