Recent experiments (notably PAMELA and, more recently, AMS-02) are ushering us into a new era of measurements of cosmic-ray fluxes with greatly reduced statistical uncertainties.    These high precision measurements offer new opportunities for a number of astroparticle problems, such as indirect dark matter searches. In particular, astrophysical anti-particle fluxes are thought to be produced only by collisions of cosmic rays on the interstellar medium, and their relatively low flux makes them a channel of choice to look for rare processes. Nonetheless, the prediction of these expected backgrounds relies on a precise modeling of the cosmic ray propagation and interaction in the Galaxy, usually constrained by « secondary over primary » ratios. I will show that the predictions for the most widely used among these probes, the boron-to-carbon ratio (B/C), strongly depends on underlying assumptions. Under some simplified hypotheses on the propagation scenario, I will present two of our studies reevaluating anti-protons and positrons fluxes in the light of new AMS02 data, and discuss the implications for dark matter. _{(continued below)}
