Structure design and test of enterprise security management system with advanced internal security

A security system for a company network is progressing as a ESM (Enterprise Security Management) in an existing security solution foundation. The establishment of the security policy is occupying a very important area in ESM of the security system. We tried to analyze the existing ESM system for this and designed a security solution structure for enhancing the internal security. We applied implementing directly IDS system and tested it. This study examined the structure of security solutions in order to build an enterprise security management system. For this purpose, we analyzed existing enterprise security management systems and, based on the results, proposed a enterprise security management system with reinforced internal security and tested the system. For the test, we used a firewall through log analysis and designed an intra-network using virtual IP system.

Secure verifiable non-interactive oblivious transfer protocol using RSA and Bit commitment on distributed environment

In this paper, we have discussed the issues concerning the basic concept and classification of OT (Oblivious Transfer). We have proposed secure verifiable non-interactive oblivious transfer protocols for the exchange of secrets on distributed environments. One is a new secure verifiable non-interactive oblivious transfer protocol using RSA, the other is that with bit commitment using one-way functions. The structure of the protocols is similar to that of the original protocols proposed by Bellare and Micali. Their protocols are based on the difficulty of the discrete logarithm problem. Our protocols are also based on the difficulty of the discrete logarithm problem. The secret in their protocol could be chosen as a random number. The security in our protocols also can be chosen as a random number. These methods have the additional functions that enable us to authenticate the sender and to protect ones denial of what he/she has sent the messages to the other. The traffic amount of transfer of the proposed methods is less than or equal to that of the conventional interactive method.

A Safe AODV (Ad Hoc On-Demand Distance Vector) Security Routing Protocol

The field that is the key issue of wire, wireless environment is security and many routing protocols are studied also at the ad-hoc network. In the mobile ad-hoc network which has no fixed base structure, the weakest point is security. This paper analyzed AODV protocol, which is a routing protocol, the important routing protocol in ad-hoc network, so that it can overcome the problem in security threats. It used the lightest and fastest message authentication code, so was able to design rather safer AODV routing protocol.

A Vulnerability Assessment Tool Based on OVAL in Linux System

Open Vulnerability Assessment Language (OVAL) is a standard language which is used to detect the vulnerability of local system based on the system characteristics and configurations. It is suggested by MITRE. OVAL consists of XML schema and SQL query statements. XML schema defines the vulnarable points and SQL query detects the vulnerable and weak points. This pa-per designed and implemented the vulnerability assesment tool with OVAL to detect the weak points in Linux System. It has more readability, reliability, scalability and simplicity than traditional tools.

Personal Color Decision System Using Fuzzy Logic

This paper, which is based on the research in the personal color decision system, uses the fuzzy logic and fuzzy ratiocination rule to improve the personal color decision method of the existing personal color system and to get more objective and reliable result for personal color. We propose the method which constructs more systematic color selection system using personal color database and fuzzy logic.

Traffic Signal Planning Using a Smart Agent System

The multi-agent systems approach can provide a new desirable solution to the problems of traffic congestion and traffic accidents. Currently, a traffic simulator is needed to understand and explore the difficulties in agent-oriented traffic control. Therefore, in this paper, we propose an electro-sensitive traffic light using a smart agent algorithm to reduce traffic congestion and traffic accidents. Specifically, we designed and implemented a system to create optimum traffic signals in congested conditions using smart agent algorithms. In order to solve these problems, our approach antecedently creates an optimal traffic cycle of passenger car units at the bottom traffic intersection. Mistakes are possible due to different car lengths, car speeds, and the length of the intersection. Therefore, our approach consequently reduces car waiting time and start-up delay time using fuzzy control of feedback data. Urban traffic situations are extremely complex and highly interactive. The proposed method adaptively controls the cycle of traffic signals even though the traffic volume varies. The effectiveness of this method was shown through the simulation of multiple intersections.

A development of intrusion detection and protection system using netfilter framework

Information can be leaked, changed, damaged and illegally used regardless of the intension of the information owner. Intrusion Detection Systems and Firewalls are used to protect the illegal accesses in the network. But these are the passive protection method, not the active protection method. They only react based on the predefined protection rules or only report to the administrator. In this paper, we develop the intrusion detection and protection system using Netfilter framework. The system makes the administrators management easy and simple. Furthermore, it offers active protection mechanism against the intrusions.

Implementation of Smart Car Using Fuzzy Rules

We proposed an algorithm to automatically control the seat, and notify dangerous traffic conditions for smart car system. The system is needed to adapt to both the driver and the circumstance for maximum convenience and safety. In order to solve these problems, we proposed an algorithm for developing smart vehicles.

Smart pulse wave detection system using intelligence

The pulse rate in the human species is a significant factor in oriental medicine. Pulse wave is a potential energy which has been generated by main artery expansion from the left ventricle, transforms into kinetic energy and passes through the vessel wall to the peripheral nervous system. In this paper, observations of patterns will be used to determine the blood circulation pulse wave which has been differentiated twice through the process of APG (Accelerated Photoplethysmo Graph). Moreover in this paper, it proposed the algorithm which diagnoses the patients health condition using intelligence method.
