Abstract
A dynamic path verification method based on reorganization of authentication fragments is proposed. The method includes: sending an initial expected path verification structure to a data packet sending end via a guarantee service node, and sending notification information to the respective routing nodes on an initial expected path; after updating the initial expected path to a new expected path, inserting the new expected path verification structure into a subsequent data packet to be sent, verifying the data packet by other nodes except a migration node, and sending the subsequent data packet to be sent to a next hop of routing node; performing the parsing verification on the received data packet by the migration node.
