Diagram of solution for urban communication systems

The task is to provide a secure data channel for legitimate users using urban telecommunication lines. Description of the layout of the complex:
  • QCS (Quantum Communication Systems) are connected by two optical fibers for a quantum channel and a synchronization channel;
  • Software for creating an encrypted network tunnel and QCS software are run on the QCS sender and receiver modules; Client personal computers are used as traffic generators (via Ethernet interface);
  • Management of the Complex is ensured with the help of a PC as part of the blocks of the sender and receiver of the QCS and the software installed on them;
Hardware Specification:
  • Sender unit of QCS (“Alice”) – 1 pc;
  • Receiver unit of QCS (“Bob”) – 1 pc;
  • Dedicated “dark” fiber for transmitting the QCS quantum channel;
  • Optical fiber for transmitting the QCS synchronization signal;
  • Client PC (“Client”) with Ethernet 10/100/1000 Mbit / s interface – 2 pcs.;
  • Ethernet channels for communication between the QCS sender and receiver units with each other and with the Client’s PC;
On the sender and receiver blocks (“Alice” and “Bob”) should be installed:
  • NauLinux 7.4 operating system;
  • Specialized QCS software designed to generate quantum keys;
  • Specialized software for creating an encrypted tunnel with AES-256 encryption with frequent change of key information;
On client PCs must be installed:
  • Operating system NauLinux 7.4 or Microsoft Windows version no lower than 7;
