We introduce the notion of \\emph{universal parameters} as a method for generating the
trusted parameters for many schemes from just a single trusted setup. In such a scheme
a trusted setup process will produce universal parameters $U$. These parameters can
then be combined with the description, $d(\\cdot)$ of any particular cryptographic setup
algorithm to produce parameters $p_d$ that can be used by the cryptographic system associated
with $d$. We give a solution in the random oracle model based on indistinguishability obfuscation.
