Yes, there indeed is a lot of traction going on in Hadoop security space.
N yaa, the typical workloads I saw, the data comes in encrypted and then
HDFS decrypts it in a controlled execution environment. I think intel's
solution is already doing it in this fashion. One can explore and move
ahead.
There are quite a few projects that are looking into this. I myself am part of
a TSB (part government funded research) project involving securing data in the
cloud. Generally the data is secured in a layer on top of hadoop rather than
specifically as part of hadoop itself.
Our solution esse
Data security is one of the major challenges being faced for Hadoop
computing. And now, when people have started using more of public clouds
OVER private hadoop clusters, the concerns have gained a priority.
There is a good demo from intel below. Might give you more insights :

Data are secured only if you are using kerberos authentication. Also is it
possible to enable ssl encryption (although I had somy issues with QJM and
data encryption)
