We have access to the information of everywhere almost instantaneously with countless kind of devices. We can download and transmit information from one place to another in seconds, something unimagined some decades ago. The problem today is not the amount of information that we can send/receive, neither the speed of the communication but the security of the data we want to communicate itself . Today we are more interested in protecting the information from malicious users, for instance a simply message to a friend or the password to our bank accounts are in continuous danger from cyberattacks. The unsecurity arise from the "networks" that we exploit to communicate, they are unsafe. While we are connected even to "protected" networks (wired or wireless) we are inside a system shared by other users which in principle can not only detect our presence but also access our devices and information without consent or trace.
This project will contribute to the very recent and highly growing field of quantum networks which is the pivotal step for the Quantum Internet with unbreakable security. Exploiting quantum phenomena we will exchange protected data through different laboratories of Sapienza University in order to simulate real cyberattacks from cryptographic perspective. Different mathematical and inference techniques will be applied in order to increase the amount of secure data to be generated and communicated. This networking approach with multipartite parties will be extended from two quantum sources to hopefully four of them.
