A family of novel broadcast encryption schemes based on probabilistic key pre-distribution are proposed, that enable multiple sources to broadcast secrets, without the use of asymm...
CENC (Cipher-based ENCryption) is the recently designed encryption mode for blockciphers. It is provably secure with beyond the birthday bound. In this note, we present a simple di...
We define security goals and attack models for disk encryption, and prove several relationships between the resulting security notions, and some general results about disk encryp...
In a threshold broadcast encryption scheme, a sender chooses (ad-hoc) a set of n receivers and a threshold t, and then encrypts a message by using the public keys of all the recei...

We construct a functional encryption scheme secure against an a-priori bounded polynomial number of collusions for the class of all polynomial-size circuits. Our constructions req...
