Abstract
We address emerging threats to the security of photonic
networks as these networks become heterogeneous being opened to the upper
layers, other operators, and end users. We review the potential threats, mainly
loss of the confidentiality of user data transmitted through optical fibers
and disturbances of network control, both of which could seriously damage
the entire network. We then propose a novel conceptual model of a secure photonic
network by introducing a quantum key distribution (QKD) network to its legacy
structure. Secure keys generated by the QKD network are managed by key management
agents (KMAs) and used to encrypt not only user data but also control signals.
The KMAs cooperate with the generalized multiprotocol label-switching controller
for secure path provisioning and drive photonic and modern crypto engines
in appropriate combinations. Finally, we present a roadmap of a deployment
scenario, starting from niche applications such as mission critical and business
applications and the next. Digital cinema distribution through a photonic
network is presented as an example of a niche application.
