Abstract
This application provides a secure route identification method and an apparatus. A first AS node receives a first message. The first message is used to indicate a target path for reaching a first route prefix, and the target path is used to indicate a first neighboring relationship between AS nodes on the target path. Then, the first AS node determines, based on the first neighboring relationship and neighbor information of an AS node on the target path that is stored in a blockchain, whether a security threat exists on the target path. The neighbor information of the AS node on the target path includes a second neighboring relationship between the AS node on the target path and another AS node.
