Abstract: Embodiments of this application relate to a cross-node data transmission method, applied to a relay node in a decentralized network. In an example method, after completing neighbor discovery with an adjacent node, the relay node receives a route flooding message sent by the adjacent node, and performs authentication on the route flooding message based on unidirectional node authentication information in the route flooding message. In response to determining that an authentication result is that the route flooding message is sent by the adjacent node, the relay node establishes a correspondence between the adjacent node and challenge information. The relay node receives a data packet sent by the adjacent node, and verifies the data packet based on challenge information corresponding to the node. In response to determining that the data packet is sent by the adjacent node, the relay node updates the data packet, to obtain a forwarding packet. The relay node sends the forwarding packet to a next-hop node.
