\u00a0 \u00a0 \u00a0One of the directions of development of wireless information transmission systems is based on the introduction of networks based on simple nodes used in such standards as ZigBee, Bluetooth, Wibree. Information transmitted over the network may be intercepted and used by a third party. Simplicity of design, minimum power consumption and minimum amount of memory do not allow to implement complex algorithms of cryptographic protection of information. The complexity of the protection algorithm is due to the bit size of the processor (8, 16 or 32 bits), the available amount of RAM and RAM, as well as power consumption during cryptographic conversion. The amount of memory is also important for receiving, processing and transmitting information between network nodes.
\nOne of the possible ways to increase the efficiency of cryptographic operations in hardware is to build them on the principle of “master – slave”. The method involves the use of a general-purpose processor as the central head of the device module (“master”), and a specialized arithmetic coprocessor (“master”), which performs all time-consuming operations under the control of the master.
