I'd like to point out that the entirety of ETCS (european train control system, used around the world despite the name) relies on GSM-R, which is just GSM on different frequency bands with a few extra features.
Snooping on this traffic seems benign, but… security is crumbling away under ETCS' foundation.
- iggldiggl 2y agoOriginal ETCS communication was unencrypted, but at least is already cryptographically authenticated between train and infrastructure. (Though since the authentication is based on 3DES, it's no longer entirely bullet-proof.) AFAIK however, the new ETCS baseline 4 has introduced specifications in preparation for a) switching away from GPRS to 5G-based communications (FRMCS) and b) introducing TLS-based encryption.
