Abstract:
The present invention is directed to a method and an apparatus for use in a wireless communication system, specifically, the method is directed to perform a ProSe discovery procedure by a first ProSe-enabled UE in a cellular communication system, the method comprising: encrypting a payload of a discovery signal by using a private key of the first ProSe-enabled UE; adding a public key of the first ProSe-enabled UE to the payload of the discovery signal; and transmitting the discovery signal including the payload and the public key of the first ProSe-enabled UE to one or more second ProSe-enabled UEs, wherein the public key of the first ProSe-enabled UE is used for the one or more second ProSe-enabled UEs to decrypt the payload of the discovery signal.
