Mobile handsets with all applicable Internet Protocol brought communication channels between the easy and rapid development. But this time that the security is part of the most vulnerable points. All IP-network currently being presented to analyze the current state of integration technology, and two kinds of terminal interworking between networks of different security systems are likely to occur in the course of the various security threats, vulnerabilities and expectations regarding possible measures to consider more stringent security technologies and performance analysis the present study.

Network industry is complex combined with various fields of industry, such as communication, broadcast, construction, and home appliances. Moreover, it's fairly lucrative since the growth industry makes lots of added values, interacting with the others.The network industry, usually called 'Ubiquitous', connects some home appliances and makes an integrated system that you can use them with whenever and wherever. A demand for network security, however, has skyrocketed due to the relatively low safety. It's been expected that the market of home security is going to be grown up nearly 30 percent every year. Recently, analog surveilance cameras have been replaced with digital ones, and they will be providing stronger security services taking advantage of mutual interaction with related industies. In this paper, a mobile monitoring system for home security is proposed, which makes it possible to supervise all home appliances wherever you're, using the conventional wired/wireless network infra.

We propose and develop Home Security robot system based on Sensor Network (HSSN) configured by sensor nodes including radio frequency (RF), ultrasonic, temperature, light and sound sensors. Our system can acknowledge security alarm events that are acquired by sensor nodes and relayed in the hop-by-hop transmission way. There are sensor network, Home Security Mobile Robot (HSMR) and Home Server(HS) in this system. In the experimental results of this system, we presented that our system has more enhanced performance of response to emergency context and more speedy and accurate path planning to target position for arriving an alarm zone with obstacle avoidance and acquiring the context-aware information.

This paper proposed a method that prevents data leakage and modulation and detects an unauthorized device by using AP and mobile device. Most of existing method for detecting and preventing an unauthorized device are similar to type of Evil Twin. However, in previous studies can not resolve many security accident and have the problem to cope with effectively security accident on various network. In order to solve these problem, companies prepare security accident through the varies policy and guideline. but It is hard to prevent all security accident because it is consistently increasing everyday. This paper suggests technique of detecting and preventing an unauthorized device using Context Awareness and Mobile Device Management. Firstly, when mobile device go into internal network, server distinguish access permission and authorization of mobile device using acquiring the conetxt information of mobile device. By using this result, server applies the appropriate management technique to the mobile device for leakage and accident of internal network.

Companies that handle sensitive information, led by public institutions, establish separate networks for work and the Internet and protect important data through strong access control measures to prevent cyber attacks. Therefore, systems that involve the junction where the Intranet(internal LAN for work purposes only) and the Internet network are connected require the establishment of a safe security environment through both administrative and technical measures. Mobile Device Management(MDM) solutions to control mobile devices used by institutions are one such example. As this system operates by handling sensitive information such as mobile device information and user information on the Internet network, stringent security measures are required during operation. In this study, a model was proposed to manage sensitive information data processing in systems that must operate on the Internet network by managing it on the internal work network, and the function design and implementation were centered on an MDM solution based on a network interconnection solution.

Most security solutions and middleware on home network consider internet users as approaching subject. It is unrealistic where the most subjects are mobile users who want to control home network devices. Therefore minor and fast certification structures are needed to control other devices with mobile device that has lower computing capacity. To solve the above problems, this paper wants to build safe certification frame work for internet and mobile users to control household devices safely. New certification structure is proposed to get out of heavy certification structure like PKI and to minimize encrypting and decrypting operation by compounding session key and public key.

Radio Frequency Identification system based on EPC(Electronic Product Code) Network Environment can read or write information of tagged objects, using Rf signals without direct contact. This advantage which is to provide storage ability and contactless property is better than Bar-code system. Mobile RFID system which integrates Mobile system with RFID system will provide new additional service to users. However, an advantage for obtaining information of objects using RF signal causes personal privacy problem. In this paper, we propose techniques that can protect personal privacy based on mobile. Our scheme provides privacy protection of users and is more efficiently than another application service.

Mobile network environments are the environments where mobile devices are distributed invisible in our daily lives so that we can conventionally use mobile services at any time and any place. But, Mobile devices has a many security vulnerabilities caused by lower computing of devices and security problem of wireless network. So in this paper, PKI structure is proposed to minimize encrypting and decrypting operation by compounding session key and public key on WIPI environment. Proposed secure authentication system based on korean standard cryptography algorithm will give a more firmness in mobile network and support a more secure service for mobile academic information service that KISTI future plan.

In this paper, we analyses of a traffic for authentication signaling in third generation mobile sensor network. In universal mobile telecommunication system, authentication functions are utilized to identify and authentication a mobile station and validate the service request network services. The authenticating parties are the authentication the serving general packet radio service support node access the authentication center to obtain the authentication with the mobile station. In this paper, we propose that the automatic cost-effective solution size of the authentication vector array.

This paper proposes a single sign-on scheme in which a mobile user offers his credential information to a home network running the OSGi (Open Service Gateway Initiative) service platform, to obtain user authentication and control a remote device through a mobile device using this authentication scheme, based on SAML (Security Assertion Markup Language). Especially by defining the single sign-on profile to overcome the handicap of the low computing and memory capability of the mobile device, we provide a clue to applying automated user authentication to control a remote device via a mobile device for distributed mobile environments such as a home network based on OSGi.
