We present a generic construction of a public-key encryption scheme that is resilient to chosen-ciphertext key-leakage from any hash proof system. The construction does not rely on additional computational assumptions, and the resulting scheme is as efficient as the underlying hash proof system.
We also present a generic construction of a statefull public-key encryption scheme that is resilient to chosen-ciphertext key-leakage from any hash proof system and any IND-CCA secure symmetric encryption.
