ENCRYPTING DISCOVERY MESSAGES

Methods, apparatuses, and computer-readable storage medium for encrypting discovery messages are provided. An example method at a first UE may include obtaining a discovery message that is ciphered based on at least one of a ciphering key, a ciphering algorithm, or a first set of time parameters, where the discovery message is scrambled based on at least one of a scrambling key, a scrambling algorithm, or a second set of time parameters. An example method may also include descrambling the discovery message based on at least one of the scrambling key, the scrambling algorithm, or the second set of time parameters. An example method may also include deciphering the discovery message based on at least one of the ciphering key, the ciphering algorithm, or the first set of time parameters.
