There are a number of benefits associated with the deployment of fog computing, for
example, by analyzing and computing data from Internet-of-Things (IoT) devices at the fog …

Distributed broadcast encryption (DBE) improves on the traditional notion of broadcast
encryption by eliminating the key-escrow problem: In a DBE system, users generate their …

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 …

Fog computing is a promising extension of cloud computing, and enables computing directly
at the edge of the network. Due to the decentralized and distributed nature of fog nodes …

Suppose a user wants to broadcast an encrypted message to K recipients. With public-key
encryption, the sender would construct K different ciphertexts, one for each recipient. The …

The Messaging Layer Security (MLS) architecture envisions a protocol that can establish a
key shared by a group of members, where each member controls a number of clients …

A broadcast encryption scheme allows a user to encrypt a message to $ N $ recipients with
a ciphertext whose size scales sublinearly with $ N $. While broadcast encryption enables …

The eight-volume set LNCS 14438 until 14445 constitutes the proceedings of the 29th
International Conference on the Theory and Application of Cryptology and Information …

The recent advent of cloud computing provides a flexible way to effectively share data
among multiple users. Cloud computing and cryptographic primitives are changing the way …

This paper describes the first constructions of identity-based broadcast encryption (IBBE)
using Type-3 pairings, which can be proved secure against adaptive-identity attacks based …
