  Multipartite entanglement plays a crucial role for the design of the Quantum
Internet, due to its potentiality of significantly increasing the network
performance. In this paper, we design an entanglement access control protocol
for multipartite state, which exhibits several attractive features.
Specifically, the designed protocol is able to jointly extract in a distributed
way an EPR pair from the original multipartite entangled state shared by the
set of network nodes, and to univocally determines the identities of the
transmitter node and the receiver node in charge of using the extracted EPR
pair. Furthermore, the protocol avoids to delegate the signaling arising with
entanglement access control to the classical network, with the exception of the
unavoidable classical communications needed for EPR extraction and qubit
teleportation. Finally, the protocol supports the anonymity of the entanglement
accessing nodes.
