Title:
Optimal Oblivious Priority Queues
Authors: Zahra Jafargholi, Kasper Green Larsen, Mark Simkin
Abstract:In this work, we present the first asymptotically optimal oblivious priority queue, which matches the lower bound of Jacob, Larsen, and Nielsen (SODA’19). Our construction is conceptually simple, statistically secure, and has small hidden constants. We illustrate the power of our optimal oblivious priority queue by presenting a conceptually equally simple construction of statistically secure offline ORAMs with O(\lg n) bandwidth overhead.
