Secure key distribution based optical channel characteristics

TeCIP Institute will hold a meeting of its Seminar Series on Tuesday, February 12, 2019: Adnan A.E. Hjomer, from Shanghai Jiao Tong University, will present the seminar: "Secure key distribution based optical channel characteristics".

A secure SKD scheme for data encryption in classical optical fiber channel is discussed. A Delay interferometer (DI) is used to track the random phase fluctuation inside fiber, while the reconfigurable lengths of polarization-maintaining (PM) fiber are set as the source of optical phase fluctuations. The output signals from DI are extracted as the secret key and shared between the two-legal transmitter and receiver. Because of the randomness of local environment and the uniqueness of fiber channel, the phase fluctuation between orthogonal polarization modes (OPMs) can be used as secure keys to enhance the level of security in physical layer.

The seminar will be open to everybody.
