Electrical Question: What is the Best Way to Splice Aluminum and Copper Electrical Wires?

I have a lamp with copper wiring that I want to install to my house which has aluminum wiring.

    I am putting a new ceiling lamp in my shed. The new one has 3 aluminum wires (black, white & green ground casing). The ceiling has two copper wires & one solid copper line (all inside casings). Is it ok to attach copper & aluminum? Is my green ground (aluminum) good to connect to a solid copper line?
    Many Thanks,
