The Quiet Numbers Station: Decoding Nineteen Years of GPS Cryptography

The Global Positioning System (GPS) relies on its primary L1 frequency to broadcast precise timing and orbital data, allowing receivers on Earth to calculate their exact location. Because the L1 C/A signal transmits at just fifty bits per second, every bit of this navigation data must earn its place

This year, we are celebrating 100 years of quantum mechanics. This year also marks the 50th anniversary of the publication of the Data Encryption Standard (DES), the first modern symmetric encryption algorithm in widespread use: https://archives.federalregister.gov/issue_slice/1975/3/17/12133-12139.pdf Within these 50 years, we haven't found a practical way to break it other than by brute force.

Given these vast timescales, I think it is about equally likely that quantum mechanics is wrong in a way that allows to break quantum cryptography and that our understanding of classical symmetric ciphers is wrong in a way that allows to break modern encryption algorithms like AES.

Hence, I am not sure that quantum cryptography is capable to deliver a meaningful security advantage.
