Server-Aided Hierarchical Identity-Based Encryption

2013 Fourth International Conference on Emerging Intelligent Data and Web Technologies, 2013
Hierarchical Identity-Based Encryption (HIBE) system is an important cryptographic tools. However, one of the main efficiency drawbacks of HIBE is that the computational cost during encryption phase grows with the depth of identity. Thus, before widely deployed, it is an increasing need to improve its efficiency.

Hierarchical Identity-Based Broadcast Encryption

2014
We 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 Hierarchical Identity-Based Encryption

2009
We take a bird's eye view of different identity-based encryption (IBE) and hierarchical identity-based encryption (HIBE) protocols that are available in the literature and use bilinear pairing as the principal building block. We start with the seminal work on IBE by Boneh-Franklin.

HIERARCHICAL IDENTITY-BASED PROXY RE-ENCRYPTION WITHOUT RANDOM ORACLES

International Journal of Foundations of Computer Science, 2010
In a proxy re-encryption scheme, a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been proposed in public key settings. Hierarchical identity-based cryptography is a generalization of identity-based encryption that mirrors an organizational hierarchy ...

Private Key Management in Hierarchical Identity-Based Encryption

2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System, 2007
Hierarchical identity-based encryption (HIBE) is a generalization of IBE that mirrors an organizational hierarchy, which consists of a root private key generator (PKG), domain PKGs and users. In a traditional HIBE system, users retrieve private keys from their domain PKGs, while domain PKGs request domain secret keys from the root PKG. What's more, the

A Hierarchical Identity-Based Encryption for MANETs

2011 International Conference on Computational Problem-Solving (ICCP), 2011
Mobile ad-hoc networks (MANETs) have no fixed infrastructure such as base stations or mobile switching centers, and the framework is dynamic owing to frequent changes in both topology and membership. Consequently, the trust relationships among nodes also change, and many security solutions with static configurations will become inadequate.
