FIELD: optics.
SUBSTANCE: invention relates to optical engineering and specifically to photonic quantum communication systems. Software-hardware complex for remote updating of system software of quantum key distribution modules in "star" network topology contains programmable logic integrated circuit, which provides receiving information via Ethernet interface and has STM32 microcontrollers connected to it, wherein software updates are transmitted to the device over the Internet in the form of UDP packets using the secure exchange protocol CRISP in accordance with P 1323565.1.029-2019 and the software update is performed via the UART interface.
EFFECT: simplified safe remote updating of device software.
