VISTA is a proof of concept for a V2V Security, Identity, and Trust Architecture (VISTA) example security framework implemented in Python. This proof of concept is not an implied endorsement that the VISTA framework is either sufficient or unique as a V2V security solution, but instead exists as a research and development baseline for community experimentation. Furthermore, this proof of concept implementation, while substantially functional, is not of production quality. Features and best-practices must be assumed to remain incomplete and their absence is not an endorsement of their necessitity or otherwise.
Major components include an authority responsible for authorizing link participants and managing cryptographic keys together with an associated REST API server, a transceiver which produces periodic squitters and validates received link messages, and a client CLI tool allowing user interaction with the authority server and management of transceivers. The crypto package implements utility functions and wrappers around the cryptographic libraries, while the models package includes data models for the REST API, domain (V2V link), and SQL backend.
Vista requires Python 3.7. Instructions for installing the Stanford PBC and Charm-crypto libraries are available here
Use the package manager pip to install the remaining requirements
pip install -r requirements.txtFrom the root of the repo, run the authority server listening for local-only connections:
python -m uvicorn vista.server:appRun the client to request a 10 minute authorization from the authority and start a transceiver
python -m vista.client run --duration 10Client options can be viewed from the CLI help menu
python -m vista.client [authorize|loadset|run] --helpAuthority and server parameters can be set in environment variables or a vista.env file
An entire ecosystem, including the authority server and multiple clients can be instantiated and run using Docker-compose
docker-compose up --scale client=10DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.
