Title:
Chosen Ciphertext Security from Injective Trapdoor Functions

Authors: Susan Hohenberger, Venkata Koppula, 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.
