A Note on Adaptive Security in Hierarchical Identity-Based Encryption

IACR Cryptology ePrint Archive
We present the first construction for adaptively secure HIBE, that does not rely on bilinear pairings or random oracle heuristics. Notably, we design an adaptively secure HIBE from any selectively secure IBE system in the standard model. Combining this with known results, this gives the first adaptively secure HIBE system from a wide variety of ...

HIBE: Hierarchical Identity-Based Encryption

Functional Encryption, 2021
Cryptosystems fundamentally deal with the issue of securing data communication. Public key infrastructure (PKI) model requires an authenticated public key for encryption that has to be obtained prior to initiating communication. The identity-based encryption (IBE) essentially removes the public key distribution by using an arbitrary string, e.g., an ...

Leakage-Resilient Hierarchical Identity-Based Encryption with Recipient Anonymity

International Journal of Foundations of Computer Science, 2019
As a promising public key cryptographic primitive, hierarchical identity-based encryption (HIBE) introduces key delegation mechanisms into identity-based encryption. However, key leakage and recipient anonymity issues have not been adequately addressed in HIBE. Hence, direct applications of traditional HIBE schemes will violate data security and abuse
