해양 분야에서 "e-Navigation"의 개념이 2005년 처음 소개된 이후, 최근 2~3년 전부터 국제해사기구(IMO)와 항로표지협회(IALA)에서 이행전략과 기술 표준화가 급속히 추진되고 있다. 특히 해상교통관제시스템(VTS : Vessel Traffic Service)은 항행지원정보교류가 가능한 육상국으로서 선박 통항의 안전과 효율성을 증진시키고 환경을 보호하는 e-Navigation의 핵심적 시스템으로 인식되고 있다. 최근 IALA VTS Committee에서는 출항에서 도착항까지 항행지원을 위하여 VTS 시스템간 정보 교류(IVEF:Inter-VTS Data Exchange Format)에 대한 요청으로 표준화가 진행되고 있다. 그러나 이러한 해상의 실시간 선박 교통흐름 정보는 국가적으로도 보안에 민감한 정보로서, 테러 등 역기능에 대한 우려가 있어, 안전한 정보교환은 필수적인 요소이다. 따라서 본 논문에서는 상호연동을 위한 보안 프로토콜을 설계하고 안전한 데이터 전송을 위한 보안 구조를 제시하고자 한다.

Network virtualization promises to play a dominant role in shaping the future Internet by overcoming the Internet ossification problem. However, due to the injecting of additional virtualization layers into the network architecture, several new security risks are introduced by the network virtualization. Although traditional protection mechanisms can help in virtualized environment, they are not guaranteed to be successful and may incur high security overheads. By performing the virtual network (VN) embedding in a security-aware way, the risks exposed to both the virtual and substrate networks can be minimized, and the additional techniques adopted to enhance the security of the networks can be reduced. Unfortunately, existing embedding algorithms largely ignore the widespread security risks, making their applicability in a realistic environment rather doubtful. In this paper, we attempt to address the security risks by integrating the security factors into the VN embedding. We first abstract the security requirements and the protection mechanisms as numerical concept of security demands and security levels, and the corresponding security constraints are introduced into the VN embedding. Based on the abstraction, we develop three security-risky modes to model various levels of risky conditions in the virtualized environment, aiming at enabling a more flexible VN embedding. Then, we present a mixed integer linear programming formulation for the VN embedding problem in different security-risky modes. Moreover, we design three heuristic embedding algorithms to solve this problem, which are all based on the same proposed node-ranking approach to quantify the embedding potential of each substrate node and adopt the k-shortest path algorithm to map virtual links. Simulation results demonstrate the effectiveness and efficiency of our algorithms.

In 2017, the International Maritime Organization (IMO) adopted MSC.428 (98), which recommends establishing a cyber-risk management system in Ship Safety Management Systems (SMSs) from January 2021. The 27th International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) also discussed prioritizing cyber-security (cyber-risk management) in developing systems to support Maritime Autonomous Surface Ship (MASS) operations (IALA guideline on developments in maritime autonomous surface ships). In response to these international discussions, Korea initiated the Korea Autonomous Surface Ship technology development project (KASS project) in 2020. Korea has been carrying out detailed tasks for cybersecurity technology development since 2021. This paper outlines the basic concept of ship network security equipment for supporting MASS ship operation in detailed task of cybersecurity technology development and defines ship network security equipment interface for MASS ship applications.

In the article, an analysis of the factors was carried out, which injected into the efficiency of the function of navigation systems in the minds of unimportance. Carrying out analyzes allowing for the visibility of relevant direct adjustments to the effectiveness of the function Inertial navigation systems in the minds of non-value. The designation of the navigation system was assigned to a complex of navigation systems on ships processing of the vector of navigation parameters, so that they can be victorious in the control systems of the ship's collapse, and the safety of floating is safe.

This paper describes a new progressive embedded Internet Protocol(IP) camera available for real-time image transmission. It was applied for ship safety and security on seashore area. The functions of developed embedded system was more effective and excellent than conventional systems. Nowadays, each nation has established harbor security systems to jump up their ports to international port. Recently Incheon port has tried to change man security into center security system used by image security system. The security system of Incheon port has some advantages like effectivity of security system and reduction of manpower and cost, installed by image security system with CCTV cameras at the entrance gate and around the fence. Thus in this paper, we have designed and implemented a Personal Digital Assistants(PDA) based Image Surveillance System for Harbor Security using IP Camera under ubiquitous environment. This system has big advantages which are more effective in an emergency and low cost and small manpower than conventional systems.

To improve maritime security and enhance international shipping commerce within US ports in addition to ISPS (International Ship and Port Facility Security Code), the TWIC (Transportation Worker Identification Credential) program is working on the maritime field from the October 15, 2008 in the United States. In this paper, the program is reviewed and investigated in terms of goal, benefit, solution, and related legislation so forth In addition, other maritime security programs including MMD (Merchant Mariner Document), FAST (Free and Secure Trade), SIDA (Security Identification Display Areas). and Air Cargo security program was analyzed and compared in order to obtain relationship and difference with the program in terms of enrollment frequency, list and method of security check, and profile of each program As a result of this paper, the program is mostly to improve maritime security, protect individual privacy, and enhance commerce rather than other programs.
