Collusion Resistant Broadcast and Trace from Positional Witness Encryption
Witness Encryption Trace and Revoke Broadcast Encryption
2019/1/18
An emerging trend is for researchers to identify cryptography primitives for which feasibility was first established under obfuscation and then move the realization to a different setting. In this wor...
Collusion Resistant Broadcast Encryption with Tight Reductions and Beyond
Broadcast Encryption Tight Reduction
2016/12/8
The issue of tight security in identity-based encryption scheme (IBE) has been widely investigated.
Recently, a tightly secure IBE scheme of bilinear groups in the weak multi-challenge setting has be...
Collusion Resistant Broadcast Encryption With Short Ciphertexts and Private Keys
Resistant Broadcast Encryption Short Ciphertexts

We describe two new public key broadcast encryption systems for stateless receivers. Both systems are fully secure against any number of colluders. In our first construction both ciphertexts and priva...

We introduce a simple primitive called Augmented Broadcast Encryption (ABE) that is sufficient for constructing broadcast encryption, traitor-tracing, and trace-and-revoke systems. These ABE-based con...
