Rethinking Encrypted Search: From Access Pattern Leakage to Information-Theoretic Privacy

Encrypted search has a fundamental problem: you can’t hide what you’re looking for. Even with the best encryption, search patterns leak information. My recent work develops a new approach using oblivious Bernoulli types to achieve …
