Generalization of the Selective-ID Security Model for HIBE Protocols
Selective-ID Security Model HIBE Protocols
2008/11/28
We generalize the selective-ID security model for HIBE by introducing two new security
models. Broadly speaking, both these models allow the adversary to commit to a set of identities and in
the cha...
From Selective-ID to Full Security:The Case of the Inversion-Based Boneh-Boyen IBE Scheme
Identity-based Encryption full-ID security
2008/9/18
In this note we remark that the inversion-based selective-ID secure identity-based encryption
(IBE) scheme from Boneh and Boyen can be bootstrapped to full-ID security using
a technique by Waters.
Constant Size Ciphertext HIBE in the Augmented Selective-ID Model and its Extensions
Constant Size Ciphertext HIBE Augmented Selective-ID Model Extensions
2008/9/10
At Eurocrypt 2005, Boneh, Boyen and Goh presented a constant size ciphertext hierarchical
identity based encryption (HIBE) protocol. Our main contribution is to present a variant of the
BBG-HIBE.
