Chosen Ciphertext Security from Injective Trapdoor Functions

Susan Hohenberger and 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.

Category / Keywords: foundations / public-key cryptography, CCA security, trapdoor functions
