Abstract:
A security protection method and an apparatus to implement security protection for a plurality of non-access stratum (NAS) connection links. The method includes determining, by a terminal, a first parameter, where the first parameter is used to indicate an access technology used to transmit a non-access stratum NAS message. The terminal can support at least two access technologies, and can separately maintain a corresponding NAS COUNT for each of the at least two access technologies. The method further includes performing, by the terminal, security protection on the NAS message based on the first parameter, a NAS key, and a NAS COUNT corresponding to an access technology used to transmit the NAS message. This application is applicable to a process of performing security protection on a NAS message.

Claim (Index 8):
The method according to  claim 1 , wherein the NAS message is a downlink NAS message, wherein the COUNT comprises a downlink NAS COUNT associated with the type of access technology, wherein the NAS key comprises at least one of decryption key or an integrity protection key, and wherein performing security protection on the NAS message comprises:\n decrypting, by the apparatus, the NAS message based on the first parameter, the decryption key, and the COUNT; or performing, by the apparatus, integrity protection verification for the NAS message based on the first parameter, the integrity protection key, and the COUNT.
