The invention provides a time-triggered vehicle network message authentication method based on a hierarchical multi-layer unidirectional key chain, which belongs to the time-triggered vehicle network data authentication method under the Internet of Vehicles environment. The sending node is initialized, the sending node builds a hierarchical multi-layer one-way key chain and distributes the initial key; the sending node multicasts the verified message and key; the receiving node verifies the received message and key.
