Security Negotiation

Abstract: a wireless device sends, to a base station, a registration request message comprising one or more first parameters that indicate security algorithms supported by the wireless device, and comprise at least a first security algorithm with a first key length and at least a second security algorithm with a second key length. the wireless device receives, from the base station, a first radio resource control (rrc) message, wherein the first rrc message comprises a message authentication code-integrity (mac-i), and indicates a selected security algorithm, among the first security algorithm and the second security algorithm. the wireless device sends, to the base station, a second rrc message comprising a second mac-i, based on the selected security algorithm.
