Confronting the FSB with foreign intelligence requires reliable, high-tech equipment equipped with multi-level protection. A reliable barrier against hackers and other attackers are called upon to serve Russian SIM-cards with domestic encryption. It became known that they will be built on the basis of chips from Samsung. Information resources report that the decision to create their own product did not find approval in the competent circles, and they abandoned it. All the technical characteristics of the chips from the Korean manufacturer and their compliance with functional requirements, as well as the optimal price and the stated delivery time, completely satisfy the Russian side. \ In the future, other manufacturers can also supply components for Russian SIM cards with domestic encryption: the possibility of cooperation with a Chinese company Huada Semiconductor (a subsidiary of the state China Electronics Corporation) is being studied.
