In this paper, we propose a lightweight mutual authentication protocol for secure and efficient home network service. Lee et al. recently proposed an attribute-base authentication key agreement protocol using public key in home network. Its protocol provided forward secrecy but don't diminish conspicious overhead of operation using ticket. Therefore the proposed protocol provided the security and efficiency using hash function and counter. Also it can provide secure home network service by check consumer electronics control level of users after created session key.

In this paper, we propose a secure smart home network model and a novel cryptographic protocol called the Smart Home Security Protocol (SHSP). Authentication, key distribution, and encryption functions are properly supported in order to make a smart home secure, and a residential gateway (RG) plays a central role in performing these functions. According to the characteristics of networks and attached devices, we classify smart homes into three different types of sub-networks and these networks are interconnected with one another by the RG. Depending on a sub-network, we use different types of secure schemes to reduce the burden of the process and the delay in devices while it provides proper security functions. The proposed secure smart home model is implemented and verified by using a variety of embedded system environments.

Recently, LEE et al. proposed an attribute-based authenticated key agreement protocol over home network, which aimed to support authentication and key agreement between user and home server. However, if the home server is attacked in the protocol, the effects are influenced to the overall home network components severly. Thereby, this paper proposes a new ticket-based authentication protocol using user attributes between user and home devices to solve the problem. The proposed protocol supports the various levels of security to user by diversifying the network accessibility depending on user attribute. Thereby, the protocol could support more secure home network services.

Generally home networks are based on wired network and wireless network. This makes customers be capable of using electric home appliances and full-duplex multimedia services and controlling the machines without any restrictions of place or time. Now that the scope of home security is being extended, the home networks can be formed with not only personal computer but also home automation, electric home appliances, and etc. But this causes many of attacks of invasion and damages. Therefore in this paper we suggest the SSIP(Secure Session Initiate protocol) model for solving those problems. The SSIP model is able to provide an efficient authentication and reduce the time of session re-establishment and set-up by adding ability of SIP authentication to Cluster-to-Cluster environment performed on home gateway.

Home network is the connection and communication of several electronic and electrical devices at hone with the integration of several technologies like Ethernet, wireless, phone line and power-line at the residential gateway to the internet. This internet based home network can be accessed from any part of the world through any device by any poison via internet. Since home network is developed for comfortable and safe life of home users, the information flow to/from home network needs to be private. Hence the remote access of the home network must be secured. This paper analyses two secure tunneling methods, voluntary and compulsory for L2TP(Layer Two Tunneling Protocol) based VPN(Virtual Private Network) for secure remote access of the home network.

User authentication and key agreement are very important components to provide secure home network service. Although the TTA adopted the EEAP-PW protocol as a user authentication and key transmission standard, it has some problems including not to provide forward secrecy. This paper first provides an analysis of the problems in EEAP-PW and then proposes a new attribute-based authenticated key agreement protocol, denoted by EEAP-AK. to solve the problems. The proposed protocol supports the different level of security by diversifying network accessibility for the user attribute after the user attribute-based authentication and key agreement protocol steps. It efficiently solves the security problems in the EEAP-PW and we could support more secure home network service than the EEAP-AK.

With a home network, a device can dynamically join a home network, obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other devices. Devices can subsequently communicate with each other directly. Device discovery protocol defines how network services can be discovered on the network. In this paper, we propose the secure discovery method of devices that uses mutual authentication with symmetric key between devices. This method that we present distributes symmetric-key to home network devices by the home server. Using this key, mutual authentication is performed between home appliances. It enables any appliance under any middleware's control to securely communicate any other appliances.

Compared to corporation and government networks, home devices and services connected in a home networks has security threats because of the use of various wired and wireless network, middleware and protocol in digital home environment, a restricted system resource of home information appliances and the users who do not care about security. So security is critical element to provide secure services in a home network environments. In this paper we design the access control system based on RBAC to offer secure home network services.

Residential network is the hybrid technology of wireless, Ethernet, Bluetooth and RF to the internet via broadband connection at home to facilitate the convenient, safe and pleasant daily lives of home user with various home network services regardless of device, time and place. For ubiquitous development more devices will be wireless and most of them will be roaming. Since these roaming devices carry private information of daily life of residential users, the interaction among the roaming devices of residential network must be secure. This paper presents to secure registration of roaming devices using IP Security (IPSec) Protocol Suite without the need to trust foreign agents.
