It is plausible that dark sector of our universe has more than one stable particle which contribute to the observed dark matter relic abundance. I will present a generic multi-component dark matter scenario where two or three dark sector particles are stable due to the presence of discrete symmetries. As a specific two (three) component dark matter scenario, I will consider a model where a vector and Majorana fermion(s) are stable due to a dark charge conjugation symmetry.
