Oblivious RAM (ORAM) more precisely: Path ORAM

WebJun 1, 2024 · The ORAM controller includes two main components: a position map (PosMap) and a stash. The PosMap is a look-up table that records the position of each real block in the tree. During the program execution, each block is assigned a random path label. WebIn this paper, we propose the first tree-based perfectly secure ORAM scheme, named LPS-ORAM. To meet the requirements of perfectly secure ORAM, two techniques are presented. One technique is dynamic remapping associated with a mutable scope, and the other is dynamically balanced eviction. ipower outlook email settings https://cashmanrealestate.com
