Abstract:
A method and apparatus for applying security information in a wireless communication system is provided. A user equipment (UE) obtains first security information and second security information, applies the first security information to a first set of radio bearers (RBs) which is served by a master eNodeB (MeNB), and applies the second security information to a second set of RBs which is served by a secondary eNodeB (SeNB).

Claim (Index 16):
A method for applying a security key by a user equipment (UE) in a wireless communication system, wherein the UE is connected to both a first eNodeB (eNB) and a second eNB, the method comprising:\n receiving, by the UE from the first eNB, a security mode command message including a first security parameter; deriving, by the UE, a first security key for the first eNB; deriving, by the UE, a signaling key associated with the first security parameter from the first security key; applying, by the UE, integrity protection or ciphering for signaling for the first eNB by using the signaling key and the first security parameter; deriving, by the UE, a second security key for the second eNB from the first security key; deriving, by the UE, a user traffic key associated with a second security parameter from the second security key; and applying, by the UE, ciphering for user traffic for the second eNB by using the user traffic key and the second security parameter.
