Abstract
A method for security for inter-RAT carrier aggregation is disclosed. The method includes encrypting a message using an encryption technique for a first RAT. The method also includes sending, to a UE, at least a portion of the encrypted message using a different, second RAT. Sending using the second RAT does not further encrypt the at least a portion of the encrypted message. The method further includes receiving the at least a portion of the message encrypted using the first RAT protocol. Receiving uses the second, different RAT. The method also includes decrypting the at least a portion of the message using the first RAT protocol. Apparatus and computer readable media are also described.
