This work is a part of the research covered in the included paper, Formal Verification of 5G Protocols.

Using the state machine, which represents a part of the 5G state machine as described in the 3GPP 5G Specifications, we are able to find a potential attack in the 5G system. This attack, named the Cell Barred Attack, shows that even with the new cellular system, attackers are able to spoof legitimate messages from malicious base stations.

Dependencies:

NuSMV
Download binary here: http://nusmv.fbk.eu/bin/bin_download2-v2.cgi

To run:

1. Run the script

      ./translate.sh

This will generate a new version of the file fsm.smv, based on the specifications in FSM.xml.

2. Run the command

      ./<path-to-NuSMV> -bmc -bmc-length 20 <path-to-fsm.smv>

This will run the model checker on the FSM against the properties and output the counter examples.
