Analyzing the security of RDSS system from the perspective of information security

This paper analyzes the security advantages of radio determination satellite service (RDSS) in terms of signal structure and operation mechanism, and studies the potential security risks and countermeasures of RDSS from three aspects of information security: confidentiality, integrity, and availability. In particular, the use of radio frequency recording and replay (RAR) to verify the potential counterfeiting and deception security risks of RDSS has been studied prove that RDSS has vulnerabilities in resisting RAR attacks and is easily deceived by RAR attacks. The success of this deception attack exposes the security risks in the integrity and availability of the RDSS system, which can cause information confusion for end users and may also limit the frequency of attacks, preventing them from receiving normal services. Finally, several measures were proposed to improve system security in response to such security risks.
