A Keyed Sponge Construction with Pseudorandomness in the Standard Model

March 22, 2012
Donghoon Chang, Morris Dworkin, Seokhie Hong, John M. Kelsey, Mridul Nandi
The sponge construction, designed by Bertoni, Daemen, Peeters, and Asscheis, is the framework for hash functions such as Keccak, PHOTON, Quark, and spongent. The designers give a keyed sponge construction by prepending the message with key and prove a
