Abstract
Reference signals used in location estimation of a user equipment (UE) in a wireless data network can be secured against a man-in-the-middle attack by a transmitting device withholding the conveyance of transmission parameters for decoding portions of a reference signal until after the portions are transmitted. Thus, receiving devices can buffer received signals and, after receiving the transmission parameters, process the buffered signals. To further prevent an attacker device from attacking future reference signals, transmission parameters can be nondeterministic such that an attacker device obtaining a parameter at a certain period of time is unable to use the decoded parameter predict or determine subsequent transmission parameters.
