Information Encryption Based on Using Arbitrary Two-Step Phase-Shift Interferometry
Deterministic Phase-Encoded Encryption Arbitrary Two-Step Phase-Shift Interferometry Lenticular Lens Array
2013/1/30
A deterministic phase-encoded encryption system is proposed. A lenticular lens array (LLA) sheet with a particular LPI (lenticular per inch) number is chosen as a modulator (key) instead of the random...
A Novel Two-Step Approach to Surviving Facility Failures
Optical communication Networks network survivability
2015/5/25
To provide resilient services over an optical network, we first enhance virtual network representing a service request into a failure dependent and enhanced VN (FD-EVN), then map FD-EVN to the optical...
