The choice of the way to counteract leakage of information due to side electromagnetic radiation

The purpose of the article is analysis of approaches to build protecting information systems, that processed by computer equipment from leakage due to side electromagnetic radiations. The article analyzes the technical and economic indicators that determine the set of parameters that reflect the labor intensity of work to create a protected and certified informatization object according to the security of information requirements. The novelty of proposed approach lies on the analysis of spatial characteristics of the informatization object and calculation of labor intensity of the works of preparation and further certification of the computer object to the security of information requirements. Using the considered approach allows to determine the optimal of the chosen method of protection the computer equipment designed for processing protected information from leakage due to side electromagnetic radiations. The proposed method allows to evaluate the labor intensity of planned costs and material costs for implementation of preparation and certification of the informatization object. The relevant in practice is the comparison of considered approaches is presented for distributed objects of informatization, the computer equipment of which is placed in small areas inside dense urban development with small sizes of controlled area. For the specified objects the problem of oversaturation is the most acute not only by computer equipment, but also by electromagnetic noise generation, the excess of which may entail the problems with electromagnetic compatibility with the object’s wireless communication connections and the impact on the health and functional (performance) of employees

Low Cost Embedded Copper Mesh Based on Cracked Template for Highly Durability Transparent EMI Shielding Films

Embedded copper mesh coatings with low sheet resistance and high transparency were formed using a low-cost Cu seed mesh obtained with a magnetron sputtering on a cracked template, and subsequent operations electroplating and embedding in a photocurable resin layer. The influence of the mesh size on the optoelectric characteristics and the electromagnetic shielding efficiency in a wide frequency range is considered. In optimizing the coating properties, a shielding efficiency of 49.38 dB at a frequency of 1 GHz, with integral optical transparency in the visible range of 84.3%, was obtained. Embedded Cu meshes have been shown to be highly bending stable and have excellent adhesion strength. The combination of properties and economic costs for the formation of coatings indicates their high prospects for practical use in shielding transparent objects, such as windows and computer monitors
