Information-Theoretically Secure MPC against Mixed Dynamic Adversaries, by Ivan Damgård and Daniel Escudero and Divya Ravi

In this work we consider information-theoretically secure MPC against a mixed adversary who can corrupt $t_p$ parties passively, $t_a$ parties actively, and can make $t_f$ parties fail-stop. With perfect security, it is known that every function can be computed securely if and only if $3t_a + 2t_p + t_f
