Formal Verification of the TLS Protocol
This project contains two folders -
Modelling and Simulation
TLS_with_ECDSA_verify_comfirm.csp - PAT code used to verify 5 TLS 1.3 safety properties:
- Establishing the same session key
- Uniqueness of session key
- Secrecy of the session key
- Peer authenticatio
- Perfect forward secrecy (PFS)
Traffic Analysis
In this fodler we have 4 subfolders. Each folder contains analysis for each social networking website that we studied. Each sub folder contains -
- Final Order txt file that contains state transistions
- Python Script for computing transistion probabilities - this file takes
final_order.txtas input (for the respective client.) - Specific PAT Code for generating graph
- Excel sheet containing transistion probability matrix.
- Readme file
We also made our PAT code modular by writing a C# library and consolidating our PAT code to have a single code.
Final file -
emulate_network_TLS.pcsp that uses read_file.cs C# code to import transistion probability matrix and generate graph.
In the final PAT code you just need to set path_index to the relevant file -
- facebook -> 1
- twitter -> 2
- Dropbox -> 3
- whatsapp -> 4
