This paper proposes the architecture and the methods of security network management for auto-configuration of security systems by extending the existing policy-based network management architecture. The architecture and the methods proposed in this paper enable a security management sewer to automatically decide the best-suited security policy to apply to a security system and the most effective and efficient security system to perform security policy rule, based on the role and capability information of security systems and the role and time information of security policy. For integrated control of network system and security system, this paper also proposes SNMP protocol based security network topology map generator. To show the excellence of the proposed architecture and methods, we simulate and evaluate the automatic response against attacks.

We can integrate more IP blocks on a silicon die as the development of fabrication technologies and EDA tools. Consequently, we can design complicated SoC architecture including multi-processors. However, most of existing SoC buses have bottleneck in on-chip communication because of shared bus architectures, which result in the performance degradation of systems. In most cases, the performance of a multi-processor system is determined by efficient on-chip communication and the well-balanced distribution of computation rather than the performance of the processors. We propose an efficient SoC Network Architecture(SNA) using crossbar routers which provide a solution to ensure enough communication bandwidth. The SNA can significantly reduce the bottleneck of on-chip communication by providing multi-channels for multi-masters. According to the proposed architecture, we design a model system for the SNA. The proposed architecture has a better efficiency by $40\%$ than the AMBA AHB according to a simulation result.

ARIA and the Advanced Encryption Standard (AES) are next generation standard block cipher algorithms of Korea and the US, respectively. This letter presents an area-efficient unified hardware architecture of ARIA and AES. Both algorithms have 128-bit substitution permutation network (SPN) structures, and their substitution and permutation layers could be efficiently merged. Therefore, we propose a 128-bit processor architecture with resource sharing, which is capable of processing ARIA and AES. This is the first architecture which supports both algorithms. Furthermore, it requires only 19,056 logic gates and encrypts data at 720 Mbps and 1,047 Mbps for ARIA and AES, respectively.

In this paper, we designed an inter-operation architecture of 10G G-PON(Gigabit passive optical network) network and NGN(Next generation network) architecture. And, we proposed mechanism of dynamic GEM(G-PON encapsulation mode) Port-ID allocation. This is able to solve a problem of 10G G-PON inter-operation. The mechanism of dynamic GEM Port-ID allocation has OMCI(ONT management control and interface) mapping table for IP address and port number. That architecture is able to support per flow QoS(Quality of service) as well as QoS of NGN requirement. So that can improve the resource efficiency of QoS than the existing G-PON architecture.

This paper proposes an efficient network architecture for reflective memory system (RMS). Using this architecture, the time for broadcasting a shared-data to all nodes can be significantly shortened. The device named topology conversion switch (TCS) is implemented to realize the network architecture. The implemented TCS is applied to the ethernet based real time control network (ERCnet) to evaluate the performance.

Software reuse gives the meaning for rapid software development and the quality of the software. Most of the Java components/libraries open-source are available only in Java Archive (JAR) file format. When a software design enters into the development process, the developer needs to select necessary JAR files manually via analyzing the given software architecture and related JAR files. This paper proposes an automated approach, JarBot, to suggest all the necessary JAR files for given software architecture in the development process. All related JAR files will be downloaded from the internet based on the extracted information from the given software architecture (class diagram). Class names, method names, and attribute names will be extracted from the downloaded JAR files and matched with the information extracted from the given software architecture to identify the most relevant JAR files. For the result and evaluation of the proposed system, 05 software design was developed for 05 well-completed software project from GitHub. The proposed system suggested more than 95% of the JAR files among expected JAR files for the given 05 software design. The result indicated that the proposed system is suggesting almost all the necessary JAR files.

In this paper we present a new-generation sensor network processor which is not optimized in circuit level, but in system architecture level. The new design build on a conventional processor architecture, improving the design by focusing on application oriented specification, ISA, and micro-architectural optimization that reduce overall design size and advance energy-per-instruction. The design employs harvard architecture, 8-bit data paths, and an compact 19 bit wide RISC ISA. The design also features a unique interrupt handler which offloads periodical monitoring jobs from the main part of CPU. Our most efficient design is capable of running at 300 KHz (0.3 MIPS) while consuming only about few pJ/instruction.

Most of the architecture is constructed in cities. Urbanism or network, occurring in contemporary society, has changed the concept of space. For this reason, many architects now focus on the changes of the relationship between architecture and cities and the changes of modern life styles. Therefore, it is necessary for architecture, not to mention architects, to find out new design methods that are able to respond to the changes. This study starts form the thought that MVRDV, the group of architects in the Netherlands, makes a design in the process, connected with contemporary society, cities, informations, and techniques. The purpose of this study is that bring to light the MVRDV's way to design, datascape, as a new design method.

The purpose of this study is to explore ways to efficiently capture the opinions of students who are main users in the planning, planning and design of school facilities. There are many criteria for determining good schools, but in this study, the main purpose of this study was to set up the main users as students, and to analyze the differences between the network and the actual spatial structure (network) created by the hope of students' use of school space, and the direction to overcome the differences. After surveying students' opinions about their satisfaction with school space and their desire to use school space by limiting the survey target to middle and high schools in Seoul, the 'social-space network analysis' was recently established in the social science field. As a result, it was found that the proximity of space and space desired by students in the school varied greatly depending on the geographical conditions, school districts, and the status of the current facilities, and the direction of improvement specialized for each school was found.

Information communication environment integrates communication, broadcasting and internet, and Digital Convergence service emerges in result. Thus, the effective routers are needed so that they can transmit a huge number of data to core internet through appropriate base center. Therefore, the network guaranteeing QoS in transport layer supports interoperability with different wireless networks. So as to users receive necessary information anywhere seamlessly, the network architecture focuses on packet transmission and it is efficient for the control layer switches and controls packets between different networks. Since individual users take advantage of different services and data, the effective router architecture must be designed. Hence in this paper we design monitoring technique to solve security problem and to support premium service to ultimate users. Thereafter, we run opnet simulation and show the improvement of proposed router architecture.
