Through recent instances of satellite hacking threats and the development of satellite security technologies in foreign countries, this study suggests the direction of the development of satellite cybersecurity in the domestic defense sector. Satellites currently operating in Earth's orbit are an important element that cannot be missed out in modern society, and are usually used for various purposes such as communication, transportation, weather forecasting, and military purposes. However, as the space industry becomes active and the number of small satellites increases, the threat to cyber hacking is also on the rise. Here, satellite hacking not only threatens national security and military operations, but it can also have negative effects at the national level, which in turn is directly linked to economic losses. As such, cybersecurity of satellites is very important in the operation of satellites, but the current cybersecurity system relies on a one-way information and communication network, making it difficult to continue patching or upgrading the security system, and security weaknesses also exist due to the absence of a supply chain security management system. Accordingly, we wanted to present a realistic solution to provide confidentiality and stability against satellite hacking threats by describing the direction of development of satellite cybersecurity in our defense field through the development of confidential communication satellite technology using the U.S. Department of Defense's satellite jamming prevention system (OCX), the European Union, and quantum cryptography technology (QKD).
