摘要： An address verification method and a corresponding apparatus are applied to the field of communication technologies, and in particular, relate to a short-range communication technology. During specific application, a second node receives first information from a first node. The first information includes a first to-be-resolved address and a first resolving key index that are of the first node. The first resolving key index indicates a first resolving key. Then, the second node can determine an identity address of the first node based on the first resolving key index and the first to-be-resolved address. The identity address uniquely identifies the first node. The first to-be-resolved address includes verification information for verifying the first resolving key. The first resolving key corresponds to a first identity address.
