Replacing a Random Oracle: Full Domain Hash From Indistinguishability Obfuscation
Indistinguishability Obfuscation Full Domain Hash
2014/3/10
Our main result gives a way to instantiate the random oracle with a concrete hash function in ``full domain hash'' applications. The term full domain hash was first proposed by Bellare and Rogaway and...
Full Domain Hash from (Leveled) Multilinear Maps and Identity-Based Aggregate Signatures
full domain hash identity-based aggregate signatures
2014/3/11
In this work, we explore building constructions with full domain hash structure, but with standard model proofs that do not employ the random oracle heuristic. The launching point for our results will...
