Modern society as an information society, a lot of information is communicated in on-line. Specially, mobile environment based on radio communication has a characteristic of flexibility compared with wire communication and is developed rapidly. However, the more mobile technology is developed the more security for sensitive information is needed. Therefore, MTM(Mobile Trusted Module) is developed and promoted by TCG(Trusted Computing Group), which is an industry standard body to enhance the security level in the mobile computing environment. MTM, hardware security module for mobile environment, offers user's privacy protection, platform integrity verification, and individual platform attestation. On the other hand, secure migration scheme is required in case secret data or key is transferred from one platform to the other platform. In this paper, we analyze migration schemes which were described in TCG standard and other papers and then propose security maintenance scheme for secret data using USIM(Universal Subscriber Identity Module).

With the increase in the use of mobile banking service, mobile banking has become an attractive target to attackers. Even though many security measures are applied to the current mobile banking service, some threats such as physical theft or penetration to a mobile device from remote side are still remained as unsolved. With aiming to fill this void, we propose a novel approach to prevent e-financial incidents by analyzing mobile device user's input patterns. This approach helps us to distinguish between original user's usage and attacker's usage through analyzing personal input patterns such as input time-interval, finger pressure level on the touch screen. Our proposed method shows high accuracy, and is effective to prevent the e-finance incidents proactively.

As the proliferation of Internet, mobile agent related technologies are examined for possible growth and evolution. In information retrieval, network and distributed system management, and electronic commerce, mobile agent is more flexible than the traditional communication paradigm. Despite the performance benefits, mobile agent is not used widely in the market because it is very vulnerable to a variety of attacks. In many studies related the security vulnerability for a mobile agent, the high security causes the performance to degrade. In this paper, we propose and evaluate the efficient security model for mobile agent using TDGM(Trusted Domain & Guide Manager), which provides three kinds of services : the trusted domain management, the security service and the travel plan guide. The result clearly shows that this model provides high security and minimizes the performance degradation.

A mobile agent system is an infrastructure that supports the mobile agent paradigm. The main challenges encountered in designing this infrastructure are discussed in this paper. After introducing a generic mobile agent system, we discuss the design issues at two levels. System level issues like the provision of agent mobility and security, are mainly encountered in developing the runtime environments for agent execution. Language level issues, such as agent programming models and primitives, arise in providing support for mobile agent programming, mainly at the library level. This paper Identifies such system and language-level issues, and illustrates the different ways developers ate addressing them. We outline the specific challenges addressed by this dissertation, primarily in the area of mobile agent security.

Mobile Agent is an autonomous mobility technology is being applied in various fields. In particular, mobile agents execution in the Internet environment through the safe execution of the security must be guaranteed. Also, agent to run the agent, the agent's workload should be distributed. In this paper, a trust model based on the security mechanism of the agent execution is proposed. Proposed mechanism to ensure safe execution of the agent was not considered in existing relative researches for rational agent workload distribution and load balancing to improve throughput was. The proposed trust-based security mechanisms for agents to go through security analysis proved safe execution of the agent.

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.

Purpose - This study intended to investigate ways to influence on the Chinese female consumers' use of mobile payment services. For this purpose, this research investigated the relationships among security and compatibility of the mobile payment service, perceived usefulness and perceived ease of use, psychological benefit, and intention to use mobile payment. Research design, data, and methodology - This research developed a structural equation model in which the usefulness, the ease of use, and the psychological benefit are predictors and the intention to use is a dependent variable. Data were collected from China female in Jiangsu and Shandong province. Results - Empirical results showed that the security and the compatibility had a positive influence on the usefulness and the ease of use. The usefulness and the ease of use influenced on the psychological benefit respectively and the psychological benefit had a positive influence on the intention to use. Conclusions - This research contributed to the mobile payment service literature by showing how Chinese women consumers adopt the mobile payment service based on TAM. Moreover, current study introduced the security and the compatibility as antecedents of the usefulness and the ease of use and revealed the mediating role of psychological benefit. Managerially, theses results suggested retailing companies ways to influence on the Chinese female consumers' use of mobile payment services.

As telecommunication technologies in telemedicine services are developed, the expeditious development of wireless and mobile networks has stimulated wide applications of mobile electronic healthcare systems. However, security is an essential system requirement since many patients have privacy concerns when it comes to releasing their personal information over the open wireless channels. Due to the invisible feature of mobile signals, hackers have easier access to hospital networks than wired network systems. This may result in several security incidents unless security protocols are well prepared. In this paper, we analyzed authentication and authorization procedures for healthcare system architecture to apply secure M-health systems in the hospital environment. From the analyses, we estimate optimal requirements as a countermeasure to its vulnerabilities.

F-HMIPv6 is protocol that supports fast handovers for Hierarchical Mobile IPv6. Unlike HMIPv6 (Hierarchical Mobile IPv6), it sends FBU(Fast Binding Update) by predicted Router's Information for a potential handover. But, The current version of this protocol doesn't ensure impeccably between mobile node and router. To make up for the weak points of the security, we propose the architecture for F-HMIPv6 protocol to structurally reinforce the security and improve weak security of among mobile node, MAP(Mobility Anchor Point), and routers for binding update when mobile node conducts handovers.
