Security Technologies Based on Home Gateway for Making Smart Home Secure

Abstract

As home network is expanding into ubiquitous computing environment and lots of private information is accessible, it is required to protect home network system from illegal accesses and security threats in open network. In general deployment of home network, a secure home gateway is located at the boarder of each home and regarded to be a core entity providing services and controlling traffic. So in this paper, we propose a security system guaranteeing security, availability, and reliability based on the secure home gateway and describe our implementation on home network including authentication, authorization, and security policy.

A Study of Smart Home Environment and its Security Threats

“…Malicious codes are applied to alter, demolish or obtain information and in addition to permit unauthorized access. 5,10,12 The security threats of malicious codes have the most risks in a smart home environment contrasted with commercial networks because of home user's lack of unawareness about data and network security.…”

“…The attacker may imitate an unauthorized home user and access to the smart home internal network system remotely keeping in mind the end goal is to get secret data or acquire services. 5,10,12 This attack is frequently done together with others attacks, for example, replay attack.…”

“…The communication might contain confidential data which the home users do not want to be getting exposed to unauthorized users. 5,10,12 Eavesdropping is the most common recognized security threat in open systems and is an attack on confidentiality of the smart home environments.…”

“…2,5,11 The main security mechanisms for making a smart home networks secure are authentication and authorization. 2,5,9,13 Both mechanisms are needed so that to confine any intruder from gaining access in to the smart home networks. Moreover, usage of firewalls is an alternate intrusion prevention mechanism that is imperative to build security in smart homes.…”

“…Therefore, authorization mechanism are applied to figure out what level of access a specific authenticated user ought to have on network services and resources in a smart home networks. 2,5,13 Different firewall techniques are applied in order to control the networks traffic such as; packet filtering, proxy service and stateful inspection. 15 A smart home network can use each one of them together to give defence in depth.…”
