Abstract
A data packet verification method and a device improve network security. The method includes: receiving a data packet of a terminal device, where the data packet carries a first token and a service identifier, and the service identifier is used to indicate a type of a service to which the data packet belongs; obtaining first input information based on the data packet, and generating a second token based on the first input information, where the first input information includes an identifier of the terminal device and the service identifier carried in the data packet; and sending the data packet when the first token is the same as the second token.
