    Abstract: A network entity may provision a UE and a base station with parameters for securing network communications. The network entity may send a system parameter to a UE and a private security key to a base station. Additionally, the UE and the base station may each receive synchronization information from the network which may be used to create a randomness parameter. The base station may create a signature based on the private security key, a cell identifier, and the randomness parameter and include the signature in a system information message that is to be broadcasted to one or more UEs. A UE connecting to the base station may receive the system information message from the base station, determine the cell identifier, and verify the system information message based on one or more of the cell identifier, the system parameter, or the randomness parameter.

    Abstract: 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.

    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 translation: 在一方面，网络可以支持多个客户端设备。 在这种网络中，客户机设备发送与网络通信的请求，建立安全上下文，并从网络接收一个或多个加密的客户端设备上下文。 加密的客户端设备上下文使得能够重建网络上的上下文以与客户端设备进行通信，其中上下文包括与客户端设备相关联的网络状态信息。 客户端设备向包括至少一个加密的客户端设备上下文的网络发送消息（例如，包括上行链路数据分组）。 由于网络设备可以基于加密的客户端设备上下文重建客户端设备的上下文，所以网络设备可以减少在网络设备处维护的上下文的量，以便支持更多数量的客户端设备。
