In order to solve the problem of how to protect the confidentiality and integrity of the distribution network control signal transmission security problem, this paper proposes a solution for point to point quantum secure optical fiber transmission system of distribution network control signal. The solution is to combine the quantum key distribution (QKD) with one-time pad to realize the secure communication of the point to point of the distribution network control and protection signal. The simulation results show that compared with the classical key distribution system, the proposed scheme has the advantage of confidentiality, integrity and identifiability, and has the uniqueness of tightness enhanced. The security support for the interoperability of intelligent distribution network equipment is enhanced, and the security and intelligence level of the distribution network system are improved.

Solving the problem of ensuring the information security of the fiber-optics systems requires an analysis of possible methods of unauthorized access. Improving the technology of installation and operation of the fiber-optics systems not only enhances the quality and distance of information transmission over an optical cable, but also potentially expands the range of channels for possible leakage of information transmitted through it. Improving the construct of the optical fibers, the use of such technologies as wavelength division multiplexing (WDM), necessitates a complex analysis of increasing the information capacity and security of fiber-optics systems from unauthorized access. The paper compares the security of the fiber-optics systems built on the standard single mode fiber (SSMF) and dispersion shifted fiber (DSF). It is shown that, despite of the possibility of a higher information capacity, fiber-optics systems built on DSF require more careful control to avoid unauthorized access than in the case of using standard SSMF.
