Abstract: | Public communication is secure if a hostile third-party cannot decode the messages exchanged by the communicating parties. In Nash equilibrium, communication
by computationally unbounded players cannot be secure. We assume complexity averse players, and show that a simple, secure,
and costless communication protocol becomes available as the marginal complexity cost tends to zero.
