    Abstract: Accordingly the embodiments herein provide a method for reconnecting a Radio Resource Control (RRC) connection with a Radio Access Network (RAN) node by a User Equipment (UE) in a wireless communication system. The method includes transmitting a message 3 (MSG3) of a random access procedure on Signaling Radio Bearer 0 (SRB0) for reconnecting the RRC connection. The MSG3 is a request message to the RAN node with set of connection parameters. Further, the method includes receiving a message 4 (MSG4) of the random access procedure from the RAN node. The MSG4 is received on a SRB0 or a Signaling Radio Bearer 1 (SRB1). Furthermore, the method includes transmitting a message 5 (MSG5) on the SRB1 to RAN node for reconnecting RRC connection. The proposed method can be used to mitigate a replay attack on the UE in a inactive state using a nonce and a wait time interval.

    Abstract: The present invention relates to a method and a system for securing discovery information being transmitted through a direct radio signal in a wireless communication system which supports a device-to-device service, and a device-to-device communication method of a transmission terminal, according to one embodiment of the present invention, can comprise: synchronizing with a discovery resource cycle number; determining discovery channel logical timing information of a discovery physical channel through which discovery information is to be transmitted; generating security information by using a security key, the determined discovery channel logical timing information and the discovery information to be transmitted; and transmitting the discovery information including the security information through the discovery physical channel. According to one embodiment of the present invention, it is possible to prevent discovery information of a terminal to be wrongly transmitted due to a case where another rogue terminal receives and changes the discovery information of the terminal, or the like.
