PREVENTION OF REPLAY ATTACK IN LONG TERM EVOLUTION DEVICE-TO-DEVICE DISCOVERY |
摘要 |
Methods, systems, and devices are described for device-to-device (D2D) wireless communication. A device may receive a timing variable from a network while the device is in a connected mode. The device may then use the timing variable for D2D discovery message authentication. The device may compare the timing variable with a local timing variable to determine whether a difference between the two variables is within a maximum allowable offset. The device may announce the D2D discovery message to another device when the difference is within the maximum allowable offset. |
