Abstract: A short message service (SMS) message is encrypted using an encryption key stored at a user equipment and an access and mobility management function (AMF) and the encrypted SMS message is added to a payload of a non-access stratum (NAS) message that includes an NAS header. Integrity protection is applied to the NAS message using an integrity key stored at the user equipment and the AMF and the integrity-protected NAS message is transmitted. The NAS message is received via an NAS link between the user equipment and the AMF. An integrity check is performed on the NAS message using the integrity key. An encrypted short message service (SMS) message is extracted from a payload of the NAS message in response to the integrity check being successful and the encrypted SMS message is decrypted using the encryption key.

Abstract: A method and apparatus may include configuring, by a network node, a user equipment to use an aggregation of radio technologies. At least one radio bearer is established between the user equipment and the network node and is routed over an access point of an alternate wireless network. The method may also include determining whether trustworthy security is provided by the access point of the alternate wireless network. The method may also include instructing the user equipment to turn off ciphering based on the determining, wherein the ciphering is turned off for the at least one radio bearer between the user equipment and the apparatus. The method may also be used for configuring specific ciphering on selective radio bearers.

Abstract: Systems, methods, apparatuses, and computer program products directed to next generation (e.g., 5G systems) key set identifier(s) are provided. One method includes requesting, by a network node, authentication of a user equipment with an authentication server, receiving a master key and authentication parameters/vectors from the authentication server when authorization is successful, and verifying validity of the authentication request. When the verification is successful, the method may further include instantiating a security context for the user equipment and assigning a security context identifier for next generation system security context to the user equipment, and then sending a security mode command message to instruct the user equipment to instantiate security context using the security context identifier.
