Center node: "a language for probabilistically oblivious computation"
  Abstract: An oblivious computation is one that is free of direct and indirect information leaks, e.g., due to observable differences in timing and memory access patterns. This paper presents Lobliv, a core language whose type system enforces obliviousness. Prior work on type-enforced oblivious computation has focused on deterministic programs. Lobliv is new in its consideration of programs that implement probabilistic algorithms, such as those involved in cryptography. Lobliv employs a substructural type system and a novel notion of probability region to ensure that information is not leaked via the distribution of visible events. The use of regions was motivated by a source of unsoundness that we discovered in the type system of ObliVM, a language for implementing state of the art oblivious algorithms and data structures. We prove that Lobliv's type system enforces obliviousness and show that it is nevertheless powerful enough to check state-of-the-art, efficient oblivious data structures, such as stacks and queues, and even tree-based oblivious RAMs.
