Reproducible Circularly-Secure Bit Encryption: Applications and Realizations.
2015 · IACR Cryptology ePrint Archive
Abstract. We give generic constructions of several fundamental cryptographic primitives based on a new encryption primitive that combines circular security for bit encryption with the so-called repro-ducibility property (Bellare et al. PKC 2003). At the …
