An anti-interception two-dimensional optical coding communication system

Traditional two-dimensional code has small code cardinality, which is vulnerable to the brute-force attacks by eavesdroppers. In order to improve the anti-interception performance of optical fiber transmission system, we propose and construct a new two-dimensional optical code, which has large code cardinality that can be used in single user or multi-user optical transmission systems. The transmission performance of two-dimensional optical coding system is demonstrated by Optisystem simulation. Simulation results show that the proposed two-dimensional code can realize an anti-interception communication system.
