On Simulation-Sound Trapdoor Commitments
[chapter]
2004
Lecture Notes in Computer Science
We study the recently introduced notion of a simulation-sound trapdoor commitment (SSTC) scheme. In this paper, we present a new, simpler de nition for an SSTC scheme that admits more e cient constructions and can be used in a larger set of applications. Speci cally, we show how to construct SSTC schemes from any one-way functions, and how to construct very e cient SSTC schemes based on speci c number-theoretic assumptions. We also show how to construct simulation-sound, non-malleable, and
