Technical development plans for enable to long distance communication for satellite-ground communication are rapidly underway for quantum key distribution (QKD) or physical layer encryption, which enables information-theoretic secure key sharing. In our plan, we are currently working on developing a highly confidential cryptographic communication device (SeCRETS) for the purpose of demonstrating the operation of equipment in the space environment. In this presentation, we will report on the communication test on the ground using the ground model of SeCRETS, which is the same model as the equipment to be installed on the ISS, and the On-board truck optical ground station.
