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...

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...
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...
Abstract. In this paper we present a general framework for constructing efficient multicast cryptosystems with provable security and show that a line of previous work on multicast ...
Imagine many small devices send data to a single receiver, encrypted using the receiver’s public key. Assume an adversary that has the power to adaptively corrupt a subset of the...
