Functional Signatures and Pseudorandom Functions
We introduce two new cryptographic primitives: functional digital signatures and functional pseudorandom functions. In a functional signature scheme, in addition to a master signing key that can be used to sign any message, there are signing keys for a function f, which allow one to sign any message...
