Oblix and Snoopy

Read how the RISELab/Sky projects Oblix and Snoopy inspired Signal to build a better ORAM.

Rather than tread this path towards ever-increasing program complexity as we try to hand-craft obfuscation into our memory access patterns through linear scanning, we’ve built a layer of abstraction around RAM access that utilizes higher-performing oblivious RAM (ORAM) techniques. We are inspired by the systems discussed in current academic literature, such as Path ORAMOblix, and Snoopy and grateful to the researchers who developed and shared them.
