Title: NETWORK ARCHITECTURE AND SECURITY WITH ENCRYPTED CLIENT DEVICE CONTEXTS
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.
