No it isn't. The only encryption I have heard is used by security forces, and it's usually just the dispatchers.
Almost any of the security units will be suspicious if they see you with a scanner. Within the fences, I would avoid using it just because it will cause problems. If you're somewhere like Wright Brothers Memorial Park listening, it's not as much of an issue. I went planespotting there for several years and the MPs only approached me a couple of times - always very friendly. One even started a discussion about my radio because he was interested in buying one for his brother. The MPs are nice guys for the most part...88th and 445th SF guys tend to be more strict, but they don't patrol much outside the base boundaries.
