The paper presents the Internet of Nano Things operating in the telemedicine services chain. It includes analysis of systems for acquisition, processing and distribution of medical information covered in international publications. The telemedicine standards and the status of research and development of sensor and nanosensor networks were reviewed, and development directions for the discussed issues were indicated. Telemedicine could be successfully implemented in modern combat theatre scenarios. The analyses are supported with results of tests of a nanosensor network functioning in human circulatory system. Characteristic features of losses in the sent messages and delays in delivery of medical information to nanointerfaces at the interface points with BANs and WANS were examined.

Fourth-generation (4G) mobile networks are successively replaced by fifth-generation (5G) ones, based on the new releases of the 3rd Generation Partnership Project (3GPP) standard. 5G generation is dedicated to civilian users and the conducted analytical work shows that it has numerous technological gaps that prevent its direct implementation in military communications systems. However, the recent armed world conflicts showed that closed or public mobile networks are willingly used by soldiers for both private and business communications, and to conduct defensive and offensive operations as well. From the military operation viewpoint, jamming both civil and military systems is one of the essential elements of electronic warfare. This paper focuses on the practical trial of low-energy and smart jamming on a 5G private network using narrowband signals, which facilitates the reduction of the available throughput, e.g. in the time division duplex – uplink (TDD-UL) by 99%, or by 82% in the frequency division duplex – downlink (FDD-DL). This type of jamming also allows for reaching up to 25 dB of energy gain comparing to barrage jamming. The authors moreover investigated jamming the Narrowband IoT radio interface using synchronized, selective jamming. The goal was to propose energy efficient methods that will allow the jammers to work longer and be mounted on a small unmanned aerial vehicle (UAV) that can operate near the gNB. The generation of low-power jamming signals in the gNB vicinity successfully hinders detecting the jammer by the enemy’s electronic reconnaissance systems. The proposed solutions are compared with the test results for other types of jamming methods.

The paper describes a critical infrastructure testbed environment for SCADA (Supervisory Control and Data Acquisition) cyber security evaluation and assessment. This includes results of the performed analysis of important features of the critical infrastructure for determination of testbed architecture. As a result the ontology of security for critical infrastructure domain, ontology of protection elements and corresponding taxonomies of infrastructure elements and threats were proposed. A brief survey of the critical infrastructure threats and countermeasure tools was carried out. The proposed environment reflects the real control and supervision substation of electricity generation and distribution control system. SCADA system uses IEC 60870-5-104 and IEC 61850 protocols encapsulated in IPv4 datagrams. The structure of the built testbed environment was shown and its software and hardware components were described. Traffic samples collected from real power IP control and management network for use within testbed generators were analyzed and described.
