Fully Secure and Fast Signing from Obfuscation
Kim Ramchen, Brent R. Waters · 2014
In this work we explore new techniques for building short signatures from obfuscation. Our goals are twofold. First, we would like to achieve short signatures with adaptive security proofs. Second, we would like to build signatures with fast signing, ideally significantly faster than comparable signatures that are not based on obfuscation. The goal here is to create an "imbalanced'' scheme where signing is fast at the expense of slower verification.
