Abstract
We present alternative method for implementation of secure data transmission channel protected over physical layer for the "first/last mile" segment of intra-corporate network by specialized fiber optic link. Proposed solution is based on application of operating in a few-mode laser-based regime multimode optical fibers with special refractive index profile providing optical pulse strong uniquely distortions due to differential mode delay effect that allows to consider those optical fibers as "encryptor". Therefore, transmitted traffic is strongly distorted and it is unable to be processed without corresponding "decryptor" which might be either also another one optical fiber with "inversed" refractive index profile in relation to the "encryptor"-fiber or electronic dispersion compensator device modified for such application. This work is concerned with configurations of proposed "crypto" fiber optic link as well as brief description of math apparatus for design it. Some results of preliminary simulations are also represented.
