Abstract: Systems, methods, apparatuses, and computer program products for security of inter-nodal communication for VoiP lawful interception are provided. One method includes receiving, by an access node, at least one identity from an internet protocol multimedia system (IMS) node, the at least one identity used by the IMS node to intercept signaling messages, compiling a target list comprising the at least one identity, receiving a message from the IMS node when a session is established, wherein the message comprises an identity for each of the parties to the session, and comparing the identity for each of the parties to the session with the at least one identity in the target list.
