Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against ...
We prove the equivalence of two definitions of non-malleable encryption appearing in the literature— the original one of Dolev, Dwork and Naor and the later one of Bellare, Desa...
Abstract. In this paper, we reconsider the notion of plaintext awareness. We present a new model for plaintext-aware encryption that is both natural and useful. We achieve plaintex...
We present generic constructions of stateful public key encryption (StPE). We build several new StPE schemes and explain existing ones using our generic constructions. Of the new ...
We provide methods for transforming an encryption scheme susceptible to decryption errors into one that is immune to these errors. Immunity to decryption errors is vital when const...
