Tight Adaptively Secure Broadcast Encryption with Short Ciphertexts and Keys
broadcast encryption bilinear group
2018/5/2
We present a new public key broadcast encryption scheme where both the ciphertext and secret keys consist of a constant number of group elements. Our result improves upon the work of Boneh, Gentry, an...
Adaptively Secure Broadcast Encryption with Small System Parameters
Adaptive security broadcast encryption multilinear maps
2016/1/7
We build the first public-key broadcast encryption systems that simultaneously achieve
adaptive security against arbitrary number of colluders, have small system parameters, and have
security proofs...
On the Resilience and Uniqueness of CPA for Secure Broadcast
ad hoc networks secure broadcast
2014/3/6
We consider the Secure Broadcast problem in incomplete networks. We study the resilience of the Certified Propagation Algorithm (CPA), which is particularly suitable for ad hoc networks. We address th...
Adaptively Secure Broadcast Encryption under Standard Assumptions with Better Efficiency
Public-key encryption Broadcast encryption
2014/3/11
In this paper, we present an efficient public-key broadcast encryption (PKBE) scheme with sub-linear size of public keys, private keys, and ciphertexts and prove its adaptive security under standard a...
A broadcast protocol allows a sender to distribute a message through a point-to-point network to a set of
parties, such that (i) all parties receive the same message, even if the sender is corrupted,...
