Abstract: | We propose a new methodology for rational secret sharing leading to various instantiations that are simple and efficient in terms of computation, share size, and round complexity. Our protocols do not require physical assumptions or simultaneous channels, and can even be run over asynchronous, point-to-point networks. Of additional interest, we propose new equilibrium notions for this setting (namely, computational versions of strict Nash equilibrium and stability with respect to trembles), show relations between them, and prove that our protocols satisfy them. |
