Abstract
A packet parsing method includes a source device receives a first ciphertext from a control device, where the first ciphertext is used to verify reliability of a packet from a parsing device, and the parsing device is a trusted device selected on a path between the source device and a destination device. The source device obtains a second packet including the first ciphertext according to the first ciphertext and a first packet, and sends the second packet to the destination device. The parsing device obtains, according to the second packet and a device identifier of the parsing device, a third packet including verification information and the first ciphertext. The destination device receives the third packet from the parsing device, and verify reliability of the third packet using the verification information and the first ciphertext included in the third packet.
