Functional encryption is another recent tool that allows an authority to deliver functional decryption keys, for any function $f$ of his choice, so that when applied to the encryption of a message $m$, the functional decryption key yields $f\left(m\right)$. Since $m$ can be a large vector, $f$ can be an aggregation or statistical function: on encrypted data, one can get the result $f\left(m\right)$ in clear.
