Equipment verification method, user equipment and network equipment

Embodiments of the invention provide an equipment verification method, user equipment and network equipment. The equipment verification method comprises the following steps: acquiring first user equipment (UE) authentication information from the network equipment by the first UE, wherein the first UE authentication information comprises a secret key and a user identifier, and the first UE authentication information is sent by the network equipment to the second UE authorized by the first UE; processing data of a plain text by the first UE based on the secret key to acquire a first output value and to send a broadcasting message, wherein the broadcasting message comprises the first output value and an index value, the second UE confirms the first UE authentication information based on the index value and processes the data of the plain text based on the secret key to acquire a second output value, thereby discovering the first UE through comparing the first output value with the second output value. The embodiments of the invention solve the problem that, in the ProSe discovering method of the prior art, a lot of computational resource is consumed to look up the identity of the broadcaster when the discoverer has a lot of authentication UE.
