Hierarchical Identity-Based Broadcast Encryption
2014We elaborate Hierarchical Identity-Based Encryption (HIBE) with a new primitive referred to as Hierarchical Identity-Based Broadcast Encryption (HIBBE). Similar to HIBE, HIBBE organizes users in a tree-like structure and users can delegate their decryption capability to their subordinates, which mirrors hierarchical social organizations in the real ...

Identity-Based Encryption and Beyond
IEEE Security & Privacy Magazine, 2008In June 2008, the US National Institute for Standards and Technology (NIST) held a workshop entitled, "Applications of Pairing Based Cryptography: Identity-Based Encryption and Beyond," in Gaithersburg, Maryland. In a series of 14 talks and two panel discussions, the presenters at this workshop discussed several aspects of identity-based encryption ...

Identity Based Encryption Without Redundancy
2005This paper presents a first example of secure identity based encryption scheme (IBE) without redundancy in the sense of Phan and Pointcheval. This modification of the Boneh-Franklin IBE is an hybrid construction that is proved to be secure (using proof techniques borrowed from those for KEM-DEM constructions) in the random oracle model under a slightly

Multimodal biometric Identity Based Encryption
Future Generation Computer Systems, 2018Abstract In this paper, we describe the first generic construction for multimodal biometric Identity Based Encryption considering two distance measures at the same time. Current protocols for fuzzy/biometric IBE are designed either for set overlap or Euclidean distance within unimodal biometrics.
