PREVENTION OF REPLAY ATTACK IN LONG TERM EVOLUTION DEVICE-TO-DEVICE DISCOVERY Russian patent published in 2018 - IPC H04L29/06 H04W12/10 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. Device-device wireless communication method (D2D) comprises the steps of: receive a temporary variable and allow the synchronization offset from the network on the device, the time variable is received while the device is in the connected mode; using said received timing variable and synchronization offset tolerance for authenticating the device-to-device communication (D2D) communication message by comparing said received temporary variable with a local time variable to determine whether the difference between said received temporary variable and said local time variable is within said tolerance synchronization offsets.
