Quantum Secured Internet Transport
This work tackles the critical problem of securing Internet transport against quantum attacks for applications relying on TLS, though it appears incremental by building on existing QKD and TLS frameworks.
This paper addresses the threat quantum computing poses to TLS security by proposing a hybrid architecture using QKD symmetric keys with TLS to provide quantum-resistant security for Internet applications, demonstrating implementation over long-distance fibers and short-distance wireless distribution.
Quantum computing represents an emerging threat to the public key infrastructure underlying transport layer security (TLS) widely used in the Internet. This paper describes how QKD symmetric keys can be used with TLS to provide quantum computing resistant security for existing Internet applications. We also implement and test a general hybrid key delivery architecture with QKD over long distance fibers between secure sites, and wireless key distribution over short distance within each site Finally we show how this same capability can be extended to a TLS cipher scheme with perfect security.
