In recent general social surveillance systems, secure access control mechanism is needed. ONVIF establishes standards for interoperability between cameras and defines web service framework for it. In this paper we present an efficient attribute based access control mechanism for surveillance system networks which follow the ONVIF standards. It accommodates web service information security techniques and provides efficient secure access control.

Information society in recent times, lots of important information have been stored in information systems. In this situation, unauthorized person can obtains important information by piggy-backing and shoulder surfing in specific area of organization. Therefore, in this study, we proposed network group access control system by combining RFID and infrared-ray for blocking information leakage due to unauthorized access by internal threats and enhancing personnel security. So it can provides a more secure internal network environment.

A home network system is made up of subject of cyber attack from a variety factors of threatening, but also have security weakness in cases of hacking, vicious code, worm virus, DoS attack, tapping of communication network, and more. So, the necessity for a security protocol to protect user asset and personal information within a home network is gradually increasing. Thus, this paper designs and suggests a home network security protocol using user authentication and approach-control technology to prevent the threat by unauthorized users towards personal information and user asset in advance by providing the gradual authority to corresponding devices based on authorized information, after authorizing the users with a Public Key Certificate.

This study details the development of YARA rules and a detection program specifically designed to identify malware in HWP documents, a common target in cyber-attacks within South Korea. By thoroughly analyzing the unique structural features of HWP files, we developed precise YARA rules that were subsequently integrated into a custom detection tool. The program was rigorously tested on a dataset of benign and malicious HWP documents, demonstrating high detection accuracy and a low false-positive rate. This research offers a robust and practical solution for enhancing cybersecurity in environments where HWP files are frequently used, contributing valuable tools for the targeted detection of document-based malware.

암호 방식의 보안성은 암호키 보안에 커다란 영향을 받고 있어 암호 통신망 가입자가 상호간에 공유해야 하는 통신키 분배 문제가 암호학의 중요한 연구 분야가 되고 있다. 통신키를 분배 하는 방식은 크게 중앙 집중식 키 분배 방식과 공개키 분배 방식, 그리고 ID 정보에 의한 분배 방식으로 나눌 수 있다. 본 논문에서는 다자간 회의용 암호 통신키 분배 방식으로 사용할 수 있는 새로운 ID 정보에 의한 키 분배 방식을 제안하였다.

Electronic Clearance System in the Advanced Countries give sane hints Clearance System in Korea to improve. It is as follows. It is necessary to enhance the economical efficiency and rapidity on clearance system. It is important to improve the conveniency of importer and export through all day services in customs. It is necessary to control export and import goods efficiently for guarantee of security. Export entry data in export country has to linked with import entry data in import country to improve speedy, correctness, and efficiency. It is necessary to solve the security problems through the use of the latest cryptograph.

The Internet of Things (IoT) is a form of the emerging 4th industry in the 5G era. IoT is expected to develop naturally in our daily life in the 5G era in which high-speed communication will be completed. Along with the rise of IoT, concerns about security and malicious attacks are also increasing. This paper examines DoS attacks, which are one of the representative security threats of IoT and proposes a local detection and blocking system that are suitable for response to such attacks. First, systems of the LoRaWAN type, which are most actively researched in the IoT system field and DoS attacks that can occur in such systems were examined. Then, the inverse order tree algorithm using regional characteristics was designed as a cluster analysis form. Finally, a system capable of defending denial-of-service attacks in the 5G IoT system using local detection and blocking with the Euclidean distance was designed.

The first-generation RKE(Remote Keyless Entry) system is very vulnerable to replay attacks and the encryption of the second-generation RKE system is known to be disabled by four to eight signal receptions and analysis. In order to enhance the security of the RKE system, we introduce a physical-layer security methods in the RKE system and propose a technique to disable the replay attack by reducing the quality of the signal received by an eavesdropper.
