Abstract

En 中文
Identity-based matchmaking encryption (IB-ME) is an advanced encryption scheme that allows both the sender and the receiver to specify their respective identities. We study the notion of hierarchical IB-ME (HIB-ME), which augments IB-ME with delegation capabilities. Specifically, we first formalize HIB-ME and construct it based on hierarchical identity-based encryption and hierarchical identity-based signature. Moreover, as applications of the HIB-ME, we show two chosen ciphertext secure (H)IB-ME constructions for different security levels.
