DRM is a no no with CC-by-SA, it says it like this: "You may not impose any effective technological measures on the Work that restrict [the access to the work]" ( the CC-by-SA legal code part 4a)
But the license that OSM has adopted, the ODbL will allow you to do what you want with the created map, as long as you give attribution on it (and share the mapdata).
