With various sensors and communications capabilities, the Internet is growing larger as the internet can communicate with the Internet. Given the growing vulnerability of the internet market, the development of security and security is increasing, and the development of the internet is actively evolving and the development of the internet is actively being carried out. In particular, it is required to introduce lightweight and secure authentication schemes, especially those that are difficult to use due to the difficulty of using authentication schemes. Thus, the safety of the secure authentication system of the Internet is becoming very important. Therefore, in this thesis, we propose certification technologies on secure objects to ensure correct, safe communication in the context of the internet context.

Common Criteria as ISO/IEC 15408 is used to assure and evaluate IT system security. As the Prime class of security assurance requirement, CM Configuration Management needs the more principled quality activities and practices for developer must be supported. So in this paper, we propose the well-defined CM method as guideline for TOE developer based on Process model including common criteria and develop the CMPET a quantitative process evaluating tool for CM using checklist. It can support useful process analyzing data to developer, evaluator and user.

Recently, Phising attack uses trick of URL and sites, and technical concealment method which infiltrates sophisticated malicious code. However, sometimes Phising security technology cannot cover all of Phising methods. Consequently, this research proposes inspection to solve this problem. First, we can install Proxy server for a strong open information exchange of web environment between web servers and clients. Therefore, it compares and analyzes harmful site and Phising URL with White domain list, and filters them. Finally, designs for stable web based information so that we can block Phising with least regulation and active control. So the purpose of this paper is introducing this design system and structure, and inspect them.

u-TSN is a promising technology facilitating road safety and traffic management for drivers and passengers. To deploy this technology in a real environment, personal information and communicated data should be protected against malicious adversaries. Even though such adversaries would appear relatively infrequently, in such cases, the benefits of u-TSN could be disrupted and disabled. Therefore, one of the ultimate goals in the design of secure u-TSN is to protect against attacks of malicious adversaries. In this paper, we present secure communication scenario for u-TSN and implement security protocols and algorithms that are the components of the scenario on an IXP425 board. The security systems, implemented as a security module, supports secure and efficient communication for the u-TSN.

Recently, the smart phone including web and mobile service based on the reliability and extendability of cloud computing is receiving huge attention. However, most of current cloud services provide just an application service for synchronizing data between mobile entity and server. Business model developed by communication companies have problems with interoperability. This paper proposes a new service security authentication model to efficiently manage smart phone users using different business models between smartphones and to keep the reliability and extendability of cloud computing. Proposed model authenticates for smart phone users to stay with in the unified communication with smart phone user's identity and access control to effectively use the current cloud computing system.

Rapid surge in date quantity lead to increase in storage demand from corporate. The existing SAN with fiber channel is being changed to IP-based SAN environment due to installment and maintenance cost. But the IP-based network still have some similar security problems as existing TCP/IP network. Also, for the security reasons of storage traffic, data are encrypted, but with the existing system, data larger than 10G can't be handled. To address security and speed issue, this paper proposes to a structure applied to IP SAN environment with Parallel Structure Word-based FSR (PS-WFSR) as hardware.

Recently a passenger ship and liner has been spread throughout men of diversity, the space and informations is not open to general passenger. Therefore security systems are necessary for special sailors to admit them. Although security systems has a variety usage methods which are organism recognition(finger printer, iritis and vein etc) a few years ago, these usages has a defect reusing other objects because of leaving a trace. Therefore this paper designs and implements using 3D Qube image password interface which hand gestures are recognized after acquiring from 2D input image for protective marker of finger printer.

The encryption of packets increases delay and delay jitter that may degrade the quality of service (QoS) in real-time communications. So, we analyzed the delay jitter, delay, and interval delay between consecutive packets which were encrypted by the DES, 3DES, SEED and AES algorithms in this study. The interval delay and jitter of three algorithms such as the DES, SEED, AES were similar to the results of no encryption. But in the case of 3DES, the encryption of packets increases the variance of interval delay and jitter in comparison with other algorithms. we also analyzed properties of security and an efficiency of RTP security between SRTP and H.235.

Smartcard is highlighted as infrastructure that has an excellent security for executing functions such as user authentication, access control, information storage and control, and its market is expanding rapidly. But possibilities of forgery and alteration by hacking are increasing as well. This Paper makes cut off of Smartcard forgery and alteration that use angular multiplexing and private key multiplexing hologram on holographic security Encryption, and proposes system capable verfication of forgery and alteration impossible on existing smartrard by adopting smartcard chip and holographic memory chip.

The rapid growth of ubiquitous technology has increased the demand of storage capacity in mobile computing. iSCSI(Internet Small Computer Interface), a virtual storage protocol would be one of the possible solutions to resolve this problem. However, the insecure nature of this protocol makes it vulnerable to malicious attacks. In this paper, we aims to design and propose a new secure lightweight iSCSI-based virtual storage scheme for mobile devices. Suitable security mechanisms are considered in the design of our proposed solution in order to overcome existing security problems in iSCSI. Relevant experiments are tarried out and the results revealed that the efficiency of proposed algorithm in which it introduces over 100% Read/Write performance improvement compared with the IPsec approach.
