PE is a subclass of FE. This (from the other answer) is correct. Also, from my understanding, your analogy is correct. PE returns the plaintext if the predicate evaluates to true. FE, on the other hand, returns a function of the plaintext. We can say that PE is a subclass of FE, since we can use FE to implement PE. Just use the identity function. ...


At first, your syntax (Setup,GenKey,Encrypt,Query) seems to be the syntax of public-key encryption with keyword-search (PKES). In the case of predicate-based encryption, we use Decrypt rather than Query. The Sahai-Waters Fuzzy IBE I recommend Sahai and Waters: Fuzzy identity-based encryption (EUROCRYPT 2005) as a first step. I assume you know the basic of ...
