摘要: A user device having a security context with a first network based on a first key may establish a security context with a second network. In a method, the user device may generate a key identifier based on the first key and a network identifier of the second network. The user device may forward the key identifier to the second network for forwarding to the first network by the second network to enable the first network to identify the first key at the first network. The user device may receive a key count from the second network. The key count may be associated with a second key forwarded to the second network from the first network. The user device may generate the second key based on the first key and the received key count thereby establishing a security context between the second network and the user device.

摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may register to a cellular network associated with a multicast/broadcast multimedia service (MBMS). The UE may transmit, to the cellular network, a request to join the MBMS. The UE may receive, from the cellular network and based at least in part on being registered with the cellular network, a response that indicates an MBMS service key (MSK) and MSK identifier pair. Numerous other aspects are described.

摘要: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes performing an extensible authentication protocol (EAP) procedure with an authentication server via an authenticator. The EAP procedure is based at least in part on a set of authentication credentials exchanged between the UE and the authentication server. The method also includes deriving, as part of performing the EAP procedure, a master session key (MSK) and an extended master session key (EMSK) that are based at least in part on the authentication credentials and a first set of parameters; determining a network type associated with the authenticator; and performing, based at least in part on the determined network type, at least one authentication procedure with the authenticator. The at least one authentication procedure is based on an association of the MSK or the EMSK with the determined network type.

摘要: One feature pertains to a method for secure wireless communication at an apparatus of a network. The method includes receiving a user equipment identifier identifying a user equipment and a cryptographic key from a wireless wide area network node, and using the cryptographic key as a pairwise master key (PMK). A PMK identifier (PKMID) is generated based on the PMK and the two are stored at the network. A PMK security association is initialized by associating the PMK with at least the PMKID and an access point identifier identifying an access point of the apparatus. An association request is received that includes a PMKID from the user equipment, and it's determined that the PMKID received from the user equipment matches the PMKID stored. A key exchange is initiated with the user equipment based on the PMK to establish a wireless local area network security association with the user equipment.

摘要: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may participate in a registration procedure with an access and mobility management function (AMF). The UE may transmit to the AMF, as part of the registration procedure, an indication of one or more single network slice selection assistance information (S-NSSAI) or a network slice selection assistance information (NSSAI). Following, the UE may receive a control message from the AMF, wherein the control message includes one or more encrypted S-NSSAI values or an encrypted NSSAI value based on the indication. The UE may then transmit the encrypted S-NSSAI or the encrypted NSSAI to a base station as part of a message.

摘要: In an aspect, a network may support a number of client devices. In such a network, a client device transmits a request to communicate with a network, establishes a security context, and receives one or more encrypted client device contexts from the network. An encrypted client device context enables reconstruction of a context at the network for communication with the client device, where the context includes network state information associated with the client device. The client device transmits a message (e.g., including an uplink data packet) to the network that includes at least one encrypted client device context. Since the network device can reconstruct the context for the client device based on an encrypted client device context, the network device can reduce an amount of the context maintained at the network device in order to support a greater number of client devices.

摘要: Wireless communications systems and methods related to globally unique temporary identity (GUTI) reallocation for cellular-Internet of thing (CIoT) are provided. A user equipment (UE) receives, from a network, a paging associated with a mobile-terminated early data transmission (MT-EDT). The UE transmits, by the UE to the network, a data request in response to the paging. The UE receives, from the network in response to the data request, a message including a global unique temporary identifier (GUTI) and at least one of data associated with the paging or a connection release indication.

摘要: Certain aspects of the present disclosure provide techniques for managing security keys for enciphering and deciphering packets transmitted in a wireless communications system. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes obtaining an indication of a key area identifier (ID) of a first cell node, wherein the key area ID identifies a set of cell nodes that are associated with a network node that uses a first key for enciphering or deciphering messages and communicating a first set of messages with the first cell node using the first key for enciphering or deciphering the first set of messages.
