Zusammenfassung: | FIELD: electrical communications; digital communication systems. SUBSTANCE: device used for data retrieval and on-line identification has frequency divider, memory units, subtracting counter, decoding units, comparison units, logic gates, decoders, and display unit. Device functions to analyze protocols, to consider rules of session establishment and maintenance so as to receive unambiguous solution concerning use of Transmission Control Protocol (TCP) and availability of many times repeated requests for establishing as many logic communication channels as possible, to compare next data block with preceding one, and to maintain stable functioning of computer-based systems in case of unauthorized impacts (attacks). EFFECT: enlarged functional capabilities. 1 cl, 10 dwg |
