About the company: profile

RUSIM LLC

The project team has many years of experience in developing telecom solutions, starting with the development and production of an ultra-thin (within 100μm) Russian SIM card (Podsimka project) in 2009.

During this period, the team has gained practical experience in areas ranging from the development of software for inline microcontrollers to the design and serial production of card products in telecom.

Our competencies include:

  • development of the structure, logical and electrical circuit diagram of integrated circuits, topology of integrated circuits;
  • development (including writing the program code) of software for integrated circuits;
  • production of plates in a full cycle (except for photomasks) with chips and their measurement;
  • assembly of chips in a case;
  • measurement and testing of integrated circuits;
  • design and development of integrated circuits;
  • testing of integrated circuits;
  • development of application software of any complexity.

We have gained experience of working with the world's leading manufacturers of microelectronics, which allows us to develop solutions in the telecom industry according to the high level of constantly changing industry requirements.

Based on many years of experience in working with SIM cards and practical experience in the field of microelectronics, the company launched the development of a 100% Russian operating system for SIM cards (RuSim OS), which meets the requirements of mobile operators, as well as regulators in the field of information security. The domestic operating system OS RuSim is developed according to the requirements of Russian and international standards in the field of telecommunication systems, mobile communications and microelectronics.

In our opinion, the development of an in-house operating system for the SIM card microcontroller is justified in terms of technical risks, since the only alternative to it are foreign SIM card OS developers operating in the Russian market (Gemalto, Oberthur Technologies, Giesecke & Devrient, etc.) whose software products feature a closed source code and cannot be presented for audit and certification in the Russian Federation. Within the framework of the current import substitution program in the industry and the imposed sanctions, the arrangement of the SIM-cards production powered by a Russian operating system is of great current interest. The developed SIM-card operating system, with Russian authentication and session key generation algorithms implemented as part of other solutions, can be used, for example, both in in-house networks of a mobile TV reporting unit of law enforcement ministries and departments, and for services based on the technology of "virtual operator" with an in-house switching center.
