Webeach data block with a leaf in the ORAM tree. The stash is a memory that can hold a small number of data blocks at a time. The external ORAM tree stores an (address, data, leaf) triplet for each block (with address 0 reserved for dummy blocks). Path ORAM invariant. At any time, each data block in Path ORAM is uniformly randomly mapped to one of ...

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 WebFeb 27, 2024 · Comparing to Ring ORAM, the simulation shows that stash size is smaller and the amortized bandwidth is 1.5× better. In addition, the size of buffer required in ORAM refreshment is reduced from O(logN) to almost a constant, where N is the number of distinct data blocks in the server.
