An Efficient Hierarchical Key Management Scheme Using Symmetric Encryptions
The concept of hierarchical access control is that a higher privileged user (or higher level) has the ability to access data in lower privileged user (or lower level). Hierarchica...

ID-based cryptography using symmetric primitives
A general method for deriving an identity-based public key cryptosystem from a one-way function is described. We construct both ID-based signature schemes and ID-based encryption ...

Forward-Secure and Searchable Broadcast Encryption with Short Ciphertexts and Private Keys
We introduce a primitive called Hierarchical Identity-Coupling Broadcast Encryption (HICBE) that can be used for constructing efficient collusion-resistant public-key broadcast enc...
