We introduce a primitive called Hierarchical Identity-Coupling Broadcast Encryption (HICBE) that can be used for constructing efficient collusion-resistant public-key broadcast enc...
Information flow type systems provide an elegant means to enforce confidentiality of programs. Using the proof assistant Isabelle/HOL, we have specified an information flow ty...
