We discuss the recent notion of functional encryption (FE), a concept first developed in the pioneering work on Fuzzy Identity-Based Encryption (Sahai and Waters, Eurocrypt 2005).  FE associates secret keys with *functions*, whereby a secret key sk_f for a function f ``decrypts'' an encryption c of m to f(m).

Although we will discuss the state-of-the-art constructions, particular emphasis will be given to understanding definitional aspects of primitive rather than proof techniques.
