Tamarin Model of Oblivious DNS over HTTP

This repository contains a Tamarin model of Oblivious DoH.

The main model is found in odoh.m4, and can be built with:

make odoh.spthy

The model with our fix is found in odoh_fix.m4 and can be built with:

make odoh_fix.spthy

Both models can be explored in Tamarin's interactive prover by running:

tamarin-prover interactive .

Proofs are stored in the proofs folder, and can be rechecked with:

make proofs

or alternatively explored in the interactive prover by running
