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...

Direct chosen ciphertext security from identity-based techniques
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...

A New and Improved Paradigm for Hybrid Encryption Secure Against Chosen-Ciphertext Attack
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...

Traitor Tracing against Public Collaboration
Abstract. Broadcast encryption provides a convenient method to distribute digital content to subscribers over an insecure broadcast channel. Traitor tracing is needed because some ...
