We introduce a primitive called Hierarchical Identity-Coupling Broadcast Encryption (HICBE) that can be used for constructing efficient collusion-resistant public-key broadcast enc...

We give the first proof of security for an identity-based encryption scheme in the quantum random oracle model. This is the first proof of security for any scheme in this model ...

A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures. Our construction is based o...
