Optimal Bounded-Collusion Secure Functional Encryption
We construct private-key and public-key functional encryption schemes in the bounded-key setting; that is, secure against adversaries that obtain an a-priori bounded number of functional keys (also known as the collusion bound). An important metric considered in the literature on bounded-key functio...
