Broadcast Encryption Using Probabilistic Key Distribution and Applications
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...

Tightness of the Security Bound of CENC
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...

Security Notions for Disk Encryption
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...

CCA2-Secure Threshold Broadcast Encryption with Shorter Ciphertexts
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...

Functional Encryption with Bounded Collusions via Multi-party Computation
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...
