  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.
