Outsider-Anonymous Broadcast Encryption with Sublinear Ciphertexts
Abstract. In the standard setting of broadcast encryption, information about the receivers is transmitted as part of the ciphertext. In several broadcast scenarios, however, the id...

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 ...

Forward-Secure and Searchable Broadcast Encryption with Short Ciphertexts and Private Keys
We introduce a primitive called Hierarchical Identity-Coupling Broadcast Encryption (HICBE) that can be used for constructing efficient collusion-resistant public-key broadcast enc...

A fully collusion resistant broadcast, trace, and revoke system
We introduce a simple primitive called Augmented Broadcast Encryption (ABE) that is sufficient for constructing broadcast encryption, traitor-tracing, and trace-and-revoke systems...

Long-Lived Broadcast Encryption
In a broadcast encryption scheme, digital content is encrypted to ensure that only privileged users can recover the content from the encrypted broadcast. Key material is usually he...

Sequential Key Derivation Patterns for Broadcast Encryption and Key Predistribution Schemes
Abstract. We study two closely related primitives: Broadcast Encryption and Key Predistribution Schemes (KPS). Broadcast Encryption allows a broadcaster to broadcast an encrypted m...

Graceful service degradation (or, how to know your payment is late)
When distributing digital content over a broadcast channel it’s often necessary to revoke users whose access privileges have expired, thus preventing them from recovering the co...

Explicit Exclusive Set Systems with Applications to Broadcast Encryption
A family of subsets C of [n] def = {1, . . . , n} is (r, t)exclusive if for every S ⊂ [n] of size at least n − r, there exist S1, . . . , St ∈ C with S = S1∪S2∪· · · ...

Fully Collusion Secure Dynamic Broadcast Encryption with Constant-Size Ciphertexts or Decryption Keys
This paper puts forward new efficient constructions for public-key broadcast encryption that simultaneously enjoy the following properties: receivers are stateless; encryption is c...

On Black-Box Constructions of Predicate Encryption from Trapdoor Permutations
Abstract. Predicate encryption is a recent generalization of identitybased encryption (IBE), broadcast encryption, attribute-based encryption, and more. A natural question is wheth...
