In this paper we consider anonymity in the context of Broadcast Encryption (BE). This issue
has received very little attention so far and all but one of the currently available BE schemes …

We consider designing public-key broadcast encryption schemes with constant-size secret
keys and ciphertexts, achieving chosen-ciphertext security. We first argue that known CPA-to …

A broadcast encryption system generally involves three kinds of entities: the group manager
that deals with the membership, the encryptor that encrypts the data to the registered users …

A constrained pseudorandom function F: K * X → Y for a family T ⊆ 2^ X of subsets
of\mathcal X is a function where for any key k ∈ K and set S ∈ T one can efficiently compute …

Broadcast encryption aims at sending a content to a large arbitrary group of users at once.
Currently, the most efficient schemes provide constant-size headers, that encapsulate …

Abstract Standard Broadcast Encryption (BE) and Attribute-Based Encryption (ABE) aim at
sending a content to a large arbitrary group of users at once. Regarding Broadcast …

In this paper, we introduce a new cryptographic primitive called broadcast encryption with
dealership. This notion, which has never been discussed in the cryptography literature, is …

This paper proposes a framework that enables secure one‐to‐many communication for
networks with limited capabilities in the face of a strong adversary that can capture an …

Broadcast encryption (BE) allows a sender to encrypt a message to an arbitrary target set of
legitimate users and to prevent non-legitimate users from recovering the broadcast …

Abstract The Boneh-Gentry-Waters (BGW)[3] broadcast encryption scheme is optimal
regarding the overhead size. This performance relies on the use of a pairing. Hence this …
