Abstract:
This study aims to enhance the security of highspeed Low Earth Orbit (LEO) communication systems by
developing an integrated, multi-layered security framework
that addresses the limitations of current aerospace
cybersecurity measures. The primary challenge lies in ensuring
real-time data confidentiality, integrity, and authenticity in the
face of sophisticated quantum and spoofing threats. To
overcome these issues, the research contribution is the design
and evaluation of a unified framework that combines
quantum-resistant encryption using a FACT system with a
Quantis USB quantum random number generator, an LSTM
encoder-decoder model for real-time anomaly detection in
ADS-B messages, and a blockchain-based mechanism for
immutable data logging. The methodology involves
benchmarking quantum-enhanced AES against traditional
encryption schemes, training the LSTM network to detect
subtle anomalies in flight data, and assessing blockchain
scalability under high transaction loads. Results indicate
significant improvements in encryption speed and detection
accuracy—demonstrating up to a 30% increase in anomaly
detection performance—while also revealing challenges such as
increased computational overhead and scalability limitations in
blockchain implementation. The framework shows promise for
practical applications in satellite communications and air
traffic management, though further research is needed to
optimize resource consumption and enhance system resilience
under extreme operational conditions.
