Title: METHOD AND DEVICE FOR PARSING PACKET
Abstract:
Disclosed are a method and device for parsing a packet capable of ensuring reliability of a source and integrity of a parsing result and improving security. The method comprises: a source device receives a first ciphertext transmitted by a control device, the first ciphertext being used to verify reliability of a packet from a parsing device, the parsing device being a selected trusted device on a path between the source device and a destination device; the source device acquires, according to the first ciphertext and a first packet, a second packet comprising the first ciphertext; and the source device transmits the second packet to the destination device. The parsing device can acquire, according to the second packet and a device identifier of the parsing device, a third packet comprising verification information and the first ciphertext. The destination device can receive the third packet transmitted by the parsing device, and uses the verification information and the first ciphertext included in the third packet, to verify reliability of the third packet from the parsing device.
