Chosen Ciphertext Security from Injective Trapdoor Functions

Susan Hohenberger, Venkata Koppula, and Brent Waters

Abstract

We provide a construction of chosen ciphertext secure public-key encryption from (injective) trapdoor functions. Our construction is black box and assumes no special properties (e.g. ``lossy'', ``correlated product secure'') of the trapdoor function.
