Abstract. Semantic security against chosen-ciphertext attacks (INDCCA) is widely believed as the correct security level for public-key encryption scheme. On the other hand, it is o...
Self-Synchronizing Stream Ciphers (SSSC) are a particular class of symmetric encryption algorithms, such that the resynchronization is automatic, in case of error during the transm...
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...

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 ...
