Abstract
A system for securing radio access with inter-eNB carrier aggregation including a primary eNB configured to secure transmission with a user equipment. The primary eNB generates a base key and derives a set of derived keys used to secure transmission on a set of radio bearers that correspond to the set of derived keys. The system for securing radio access with inter-eNB carrier aggregation also including a secondary eNB configured to secure transmission with the UE using at least one of the set of derived keys received which corresponds to a radio bearer from the set of radio bearers used by the SeNB.
