Statistically-Hiding Commitment from Any One-Way Function
Iftach Haitner and Omer Reingold
Abstract
We give a construction of statistically-hiding commitment schemes (ones where the hiding property holds information theoretically), based on the minimal cryptographic assumption that one-way functions exist. Our construction employs two-phase commitment schemes, recently constructed by Nguyen, Ong and Vadhan (FOCS `06), and universal one-way hash functions introduced and constructed by Naor and Yung (STOC `89) and Rompel (STOC `90).
