Hierarchical ibe
Did you know?
WebIdentity-based encryption (IBE), and its hierarchical extension (HIBE), are interesting cryptographic primitives that aim at the implicit authentication on the users’ public keys by using users’ identities directly. During the past several decades, numerous elegant pairing-based (H)IBE schemes were proposed. However, most pairing-related security … WebEncryptedor combiners serve as a new abstraction that is a useful tool for designing cryptosystems, unifies constructing hierarchical IBE from vastly different assumptions, and provides a target for instantiating obfuscation applications from better tools. We define the concept of an encryptor combiner. Roughly, such a combiner takes as input n public …
