you need to farm all components from void missions. You could find out easily by visiting frosts page and clicking on the "prime" tab.

If you still have problems finding the parts here are the void droptables http://warframe.wikia.com/wiki/Orokin_Void. To find his parts just search the rewards. (capture III for blueprint (also Extermination I), Survival III for the helmet, Extermination II for Chassis, Extermination III for Systems.) You can easily find keys by running regular 15minutes survival. The only problem is, that you need specific keys but you get random rewards, meaning you could have no luck and do 10 survival runs, ending up with 10 void-keys you do not really need. However, from my perspective, i like all keys, since all void rewards are worth going for.
