Notes

MTO & ORAM

  • Memory-trace obliviousness (MTO): Even an adversary that observes memory, bus traffic, and access times while the program executes can learn nothing about the program's sensitive input and output.
  • One way to achieve MTO is to employ Obilivous RAM (ORAM), allocating all code and data in a single ORAM bank, and to also disable caches or fix the rate of memory traffic.

Naive Implementations

  • The simplest way to deploy ORAM is to implement a single, large ORAM bank that contains all the code and data
  • 10x - 100x overhead
