Hedging Public-Key Encryption in the Real World
ADVANCES IN CRYPTOLOGY - CRYPTO 2017, PT III, pp. 462-494, 2017.
Hedged PKE schemes are designed to provide useful security when the per-message randomness fails to be uniform, say, due to faulty implementations or adversarial actions. A simple and elegant theoretical approach to building such schemes works like this: Synthesize fresh random bits by hashing all of the encryption inputs, and use the res...More
