Abstract: Methods, systems, and devices for wireless communication are described that support security key derivation for handover. A network entity (e.g., an access and mobility function (AMF)) may establish an access stratum (AS) key to ensure secure communications between a user equipment (UE) and a base station. If the UE relocates to a new network entity (e.g., target network entity), the initial network entity (e.g., source network entity) may perform a handover procedure to the target network entity. In some aspects, the network entities may derive a unified AS key for the handover procedure. Additionally, the network entities may utilize one or more intermediate keys (e.g., refreshed intermediate keys) derived from, in part, respective freshness parameters for the handover procedure. The target network entity may then utilize the derived intermediate keys to derive the AS key for the handover procedure and establish communications with the UE.

Abstract: A method includes generating at least one of a re-authorization request or a re- authentication with an extensible authentication protocol. The method also includes generating an upper layer message. The method further includes bundling the upper layer message and the least one of the re-authorization request or the re-authentication request as an association request. The method further includes transmitting the association request to an access point (102, 304, 304A, 304B). Figure 4

Abstract: 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.

Abstract: 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.

Abstract: One feature pertains to a method that includes establishing a radio communication connection with a first radio access node (RAN) that uses control plane signaling connections to carry user plane data. The method also includes determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN. A reestablishment request message is transmitted to the second RAN that includes parameters that enable a core network node communicatively coupled to the second RAN to authenticate the wireless communication device and allow or reject reestablishment of the radio communication connection. The parameters include at least a message authentication code (MAC) based in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device.

Abstract: Systems and methods for providing authentication key agreement (AKA) with perfect forward secrecy (PFS) are disclosed. In one embodiment, a network according to the disclosure may receive an attach request from a UE, provide an authentication request including a network support indicator to a network resource, receive an authentication token from the network resource, such that the authentication token includes an indication that a network supports PFS, provide the authentication token to the UE, receive an authentication response including a UE public key value, obtain a network public key value and a network private key value, determine a shared key value based on the network private key value and the UE public key value, bind the shared key value with a session key value to create a bound shared key value, and use the bound shared key value to protect subsequent network traffic.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain identification information for a device and may assist in establishing credentials by which the device accesses a wireless network. The UE may establish a connection with the wireless network using its own credentials, and register the device to access the wireless network by associating the identification information for the device with the credentials of the UE. The UE may receive or establish credentials by which the device accesses the wireless network and may communicate these credentials to the device over a local connection. In some cases, the UE may authenticate the device's identification information to determine whether the device is allowed to be registered with the wireless network.
