Webto the ORAM (or WoORAM) when two or more of the k blocks are empty. Fortunately, the probability of this event is bounded, and thus the size of the stash can also be bounded with negligible stash overflow probability. The schemes will, with overwhelming probability, work for small client memory. Mainobservations ... Webqueue is simpler than the one needed to implement the “stash” in the Path ORAM con-struction. More precisely, we simply need a standard queue and a standard hash table (both of which can be implemented using commodity hardware), whereas the “stash” in [28,30,18] requires using a data structure that additionally supports sorting, or “range
