Reference Implementation

This repository also includes a simple reference implementation (in Python3), and proof-of-concept, of the SecureABC AntiBody Certificate proposal. In particular we currently demonstrate the feasibility of our user certificates with a generation and verification script written in Python and a verification app written for Android.

To generate an example SecureABC QR code, run Generate_QR_Credential.py, and to verify run either Verify_QR_Credential.py or the Android application which is located in the SecureABCVerifier directory.

. Credentials, which can be displayed as standard QR codes, are signed using ECDSA over brainpoolP512r1 and comprise a user photo, name, a unique Certificate ID (CID) number and a validity period. Credentials are completely self-contained and can be verified offline, without interacting with the signer. Revocation is based on distributing revoked CIDs to verifiers.

Example credential verification using our demonstration application:

Running the code

The requirements.txt file contains all dependencies.

To run the implmentation you can use the following commands

virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
python3 Generate_QR_Credential.py 
python3 Verify_QR_Credential.py
