In this paper, we build, in a generic way, two asymmetric cryptosystems with a careful study of their security. We present first an additively homomorphic scheme which generalizes,...

We propose a new public key trace and revoke scheme secure against adaptive chosen ciphertext attack. Our scheme is more efficient than the DF scheme suggested by Y. Dodis and N. F...

A new public key cryptosystem is proposed and analyzed. The scheme is quite practical, and is provably secure against adaptive chosen ciphertext attack under standard intractabili...

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...

The Fujisaki-Okamoto (FO) conversion is widely known to be able to generically convert a weak public key encryption scheme, say one-way against chosen plaintext attacks (OW-CPA), t...

In this paper, we formally prove that padding the plaintext with a random bit-string provides the semantic security against chosen plaintext attack (IND-CPA) for the McEliece (and ...
