Media stream transmission protection through QKD networks

Abstract

A quantum computing device determines that an eavesdropper has attempted to intercept a key on a first quantum communication channel that is using a first quantum key distribution (QKD) protocol, wherein media is being transmitted over the first quantum communication channel between a first entity and a second entity. The quantum computing device accesses a data structure comprising a plurality of rules, each rule identifying an action to take based on an amount of a key detected by an eavesdropper and a type of media being transmitted over the first quantum communication channel. The quantum computing device obtains, based on an amount of the key detected by the eavesdropper and a type of the media, a rule from among the plurality of rules in the data structure. The quantum computing device performs, based on the rule, an action that protects the media before the key is invalidated.
