End-to-end Secured Fiber Optic Communication Using a Novel Encryption Algorithm

Abstract

Fiber optic communication has grown in popularity in recent decades as a result of its several advantages over conventional cable communication. Fiber optic communication allows for a download speed of 100 Mb/s with minimal latency and a fast upload speed. Despite the fact that fiber optics can transfer enormous amounts of data swiftly over great distances, it is susceptible to a variety of security threats. It is simple to tap into the fiber optic cable. Fiber optic cable is a thin strand of glass or plastic which is used to transmit data from one place to other. A unique encryption method based on the Advanced Encryption Standard (AES) is used to provide end-to-end secure fiber optic communication. It employs a variable key cypher in which the original key is used to generate a sequence of AES sub keys, with feedback from previous cypher blocks, and each sub block is encrypted using multiple sub keys. The performance of the proposed encryption algorithm is simulated and examined. The simulation results suggest that the proposed method in fiber optic communication delivers strong end-to-end security.
