A Hierarchical Identity Based Encryption (HIBE) system is anonymous if the ciphertext reveals no information about the recipient’s identity. create it. While there are multiple c...
In a fuzzy identity-based encryption (IBE) scheme, a user with the secret key for an identity ID is able to decrypt a ciphertext encrypted with another identity ID if and only if I...
We identify and fill some gaps with regard to consistency (the extent to which false positives are produced) for public-key encryption with keyword search (PEKS), providing new de...

In this paper we introduce a new primitive called identity-based encryption with wildcards, or WIBE for short. It allows a sender to encrypt messages to a whole range of receivers ...
