Info:
Read the intro, looked at the performance.
Work addresses the problem of hiding access patterns from a storage provider. Not much work has been done in the area. Previous work was too expensive. This work allows queries to take on the order of 100s of ms. Some of the cost is due to the implementation: lack of parallelism and use of Java. On the other hand, the protocol itself requires multiple round-trip times, and so the cost would still be too high. This is a problem that seems to be not worth solving, at least for now. Get the low-hanging fruit first: access control, controlled sharing, ...
