Research and Implementation of Gateway Security Technology in Internet of Things

Abstract

This article introduces the existing home gateway architecture, discusses its security risk, and researches and implements a security algorithm to ensure reliable communication between home network and mobile Internet, in view of the increasing popularity of home networking gateway and Internet connection communication security issues. The algorithm takes the public key cryptography as the core, gives the concrete implementation algorithms and procedures, and for the lack of public key encryption, the standard communication protocol is extended and MD5 hash algorithm is used, to solve the problem of data encryption and decryption, and prevents the attack of the middleman. It provides a safe environment to communicate between home network and the Internet.
