Indirect searches can be used to test dark matter models against expected signals in various channels, in particular antiprotons. With antiproton data available soon at higher and higher energies, it is important to test the dark matter hypothesis against alternative astrophysical sources, e.g. secondaries accelerated in supernova remnants. We investigate the two signals from different dark models and different supernova remnant parameters, as forecasted for the AMS-02, and show that they present a significant degeneracy.
