On the orthogonal vector problem and the feasibility of unconditionally secure Leakage-Resilient computation

Popis výsledku v původním jazyce

We consider unconditionally secure leakage resilient two party computation. Security means that the leakage obtained by an adversary can be simulated using a similar amount of leakage from the private inputs or outputs. A related problem is known as circuit compilation, where there is only one device doing a computation on public input and output. Here the goal is to ensure that the adversary learns only the input/output behaviour of the computation, even given leakage from the internal state of the device.We study these problems in an enhanced version of the ?only computation leaks?model, where the adversary is additionally allowed a bounded amount of global leakage from the state of the entity under attack. In this model, we show the first unconditionally secure leakage resilient two-party computation protocol.
