We propose a new variant of the Cramer-Shoup KEM (key encapsulation mechanism). The proposed variant is more efficient than the original Cramer-Shoup KEM scheme in terms of public...

We present a new encryption scheme which is secure against adaptive chosenciphertext attack (or CCA2-secure) in the standard model (i.e. without the use of random oracle). Our sch...

We describe a new encryption technique that is secure in the standard model against adaptive chosen ciphertext (CCA2) attacks. We base our method on two very efficient Identity-Ba...
