  The main service provided by the coming Quantum Internet will be creating
entanglement between any two quantum nodes. We discuss and classify attacks on
quantum repeaters, which will serve roles similar to those of classical
Internet routers. We have modeled the components for and structure of quantum
repeater network nodes. With this model, we point out attack vectors, then
analyze attacks in terms of confidentiality, integrity and availability. While
we are reassured about the promises of quantum networks from the
confidentiality point of view, integrity and availability present new
vulnerabilities not present in classical networks and require care to handle
properly. We observe that the requirements on the classical
computing/networking elements affect the systems' overall security risks. This
component-based analysis establishes a framework for further investigation of
network-wide vulnerabilities.
