Abstract: Method and apparatus for secure access control in wireless communications are disclosed. In an example, a method includes receiving a broadcast message including system information, identifying a first set of hashed identifiers (IDs) and a first random number based on the system information, and each ID of the first set of hashed IDs is individually hashed using at least the first random number. The method also includes calculating a first hash value for each ID of a second set of IDs using at least the first random number, determining whether at least a hashed ID of the second set of IDs matches a hashed ID of the first set of hashed IDs, and sending a request message based on a determination that at least a hashed ID of the second set of IDs matches a hashed ID of the first set of hashed IDs.

Abstract: Method, apparatus and systems are disclosed that may be implemented in a Wireless Transmit/Receive Unit (WTRU) for unicast communication with another WTRU. The method may include sending, by the WTRU to the other WTRU via a PC5 interface, a communication request indicating first security information for the WTRU and receiving, by the WTRU from the other WTRU via the PC5 interface, information which is integrity protected indicating second security information for the other WTRU. The method may also include deriving, by the WTRU from the indicated second security information, a first set of security keys for communication via a first layer using the U-plane and a second set of security keys for communication via a second layer using the C-plane; and sending, by the WTRU to the other WTRU via the PC5 interface, a message that is at least integrity protected using the derived first set of keys.

Abstract: Systems, methods, and instrumentalities are provided for vehicle to everything (V2X) service oriented link establishment. A first wireless transmit receive unit (WTRU) may broadcast a direct communication request message. The direct communication request message may include a first security context identifier (ID). The first WTRU may receive a direct security mode command message from a second WTRU. The direct security mode command message may include a second security context ID. The first may determine a third security context ID by combining the first security context ID and the second security context ID. The first WTRU may establish, using the third security context ID, a secure direct communication link with the second WTRU. The first WTRU may generate, based on the third security context ID, a security context entry for the secure direct communication link with the second WTRU.
