Multicast network security using quantum key distribution (QKD)

We reviewed the confidentiality and authentication for multi-party applications. A conceptual model of a secure multicast network has been presented by adding a quantum key distribution (QKD) network to its architecture. The model is divided into three phases, the first phase, QKD network generate secure keys to encrypt not only data but also authentication process. The second phase, authentication making sure that no one except the legitimate user receive the message and making sure that nobody except the legitimate sender writes or modifies it. In the last phase, Multicast network encrypt the data by secure key and send it to receivers. The proposed scheme amid to provide a secure end to end communication for multicast network.
