This paper studies reliability and security of information transmission in networks. We consider the framework of Franklin and Wright (J. Cryptol. 13(1):9'30, 2000): multicast communication and byzantine adversary. Franklin and Wright studied particular neighbor graphs with neighbor-disjoint paths. The aim of the present work is to drop this assumption and to give necessary and sufficient conditions on the neighbor graph allowing reliable and secure information transmission.
