Abstract: We will discuss the search of light dark matter (DM) at the cosmic frontiers such as large volume neutrino experiments and DM direct detection experiments. This is based on the scenarios of boosted DM which include the heavy and light DM components. Assuming a large hierarchy in the masses of the two DM components, the lighter one can be produced relativistically via annihilation of the heavy DM pair at the current universe, which mimic the signals of neutrino from the DM annihilation. We introduce additional dark sector which induces inelastic primary scattering with the targets followed by secondary cascade signals, subtracting the background events.
