Data Transmission Security Module of Distributed System Based on Network Coding

Abstract

Distributed storage systems often use replica mechanism to achieve redundancy, which often leads to large storage overhead and repair bandwidth overhead. In order to improve the overall performance of the system, network coding is introduced into the distributed storage system. This paper mainly studies the design of data transmission security module of distributed system based on network coding. This paper first analyzes the principle of network coding, and compares the transmission modes between butterfly network model and routing. Aiming at the problem of large amount of data encryption in distributed file system, this paper studies the encryption mechanism of HDFS system based on network coding, proposes a lightweight encryption mechanism, and carries out simulation experiments.
