Through the increment of requirement for EC(Electronic Commerce) oriented communication services, security multicast communications is becoming more important. However, multicast to EC environment is much different from unicast concept most network security protocols. On the network security, using mandatory access control of multilevel architecture which assigns a specific meaning to each subject, so we accomplish access control. In this way, access control security based on the information security level is proposed. A security protocol based on the architecture proposed in this paper would be utilized in security multicast communications, group key management service and leveled security service through multilevel EC security policy, Also we discuss and propose the security level scaleability and key management method on the network.

To acquire certificate of security evaluation for information protection Products, it is necessary for a designer to grasp the threats listed in a protection profile and to reflect them in the product design. BDPP is a protection profile for the biometric devices. In this paper, we applied BDPP to a Match-on-Card, and ertracted some security requirements to protect biometric data against threats. We also studied some countermeasures satisfying the security requirements.

In this paper, a security mechanism for a VoIP system based on SIP was implemented. This was satisfied sec security requirement of RFC 3261. The SIP standard proposes a HTTP digest authentication for user authentication mechanism, TLS for hop-by-hop security and S/MIME for end-to-end security. SRTP draft was implemented for media security. We also analyzed security of proposed SIP standard.

Quite recently, Zhou, Lu and Cao proposed a proxy-protected signature scheme based on the RSA assumption and two proxy-protectcd schemes based on the hardness of integer factorization. Dey also provided a security proof for each signature scheme in the random oracle model. In this paper, we show that their schemes do not satisfy a security requirement necessary for proxy signature schemes. This results in generating proxy signature without fay Permission from an original signer.

Information technology plays an important role in healthcare. The cloud has several applications in the fields of education, social media and medicine. But the advantage of the cloud for medical reasons is very appropriate, especially given the large volume of data generated by healthcare organizations. As in increasingly health organizations adopting towards electronic health records in the cloud which can be accessed around the world for various health issues regarding references, healthcare educational research and etc. Cloud computing has many advantages, such as "flexibility, cost and energy savings, resource sharing and rapid deployment". However, despite the significant benefits of using the cloud computing for health IT, data security, privacy, reliability, integration and portability are some of the main challenges and obstacles for its implementation. Health data are highly confidential records that should not be made available to unauthorized persons to protect the security of patient information. In this paper, we discuss the privacy and security requirement of EHS as well as privacy and security issues of EHS and also focus on a comprehensive review of the current and existing literature on Electronic health that uses a variety of approaches and procedures to handle security and privacy issues. The strengths and weaknesses of some of these methods were mentioned. The significance of security issues in the cloud computing environment is a challenge.

Smart factory of Manufacturing sector is rapidly spreading, globally. In case of domestic, it is on going based on KOSF. It is neither lack of invest nor security of information due to it has been spread from manufacturing sector. Hence, that's very difficult to efficiency prevent from new type of intimidation and security accident happened sometimes from this situation. According to research information security condition with recognized new menace, there is a most efficient way is provide education of information security without any extra budget to safely spread smart factory. Thus, this study of research has developed security awareness training curriculum from international standard, requirement of the industry, and curriculum of educational institution based on NCS (National Competency Standard). It is be very helpful to spread smart factory safely due to expert group has been test of validity.

As telecommunication technologies in telemedicine services are developed, the expeditious development of wireless and mobile networks has stimulated wide applications of mobile electronic healthcare systems. However, security is an essential system requirement since many patients have privacy concerns when it comes to releasing their personal information over the open wireless channels. Due to the invisible feature of mobile signals, hackers have easier access to hospital networks than wired network systems. This may result in several security incidents unless security protocols are well prepared. In this paper, we analyzed authentication and authorization procedures for healthcare system architecture to apply secure M-health systems in the hospital environment. From the analyses, we estimate optimal requirements as a countermeasure to its vulnerabilities.

최근 아파트의 월패드 해킹 사건과 같이 사물인터넷의 보안이 매우 심각한 상황이다. 사물인터넷은 자동화된 데이터 수집, 분석, 의사결정으로 효율성과 생산성 향상하고, 실시간으로 모니터링이 가능하면서 저비용으로 개발이 가능하다. 그리고 현재 인공 지능, 빅 데이터 및 클라우드 컴퓨팅 등 다양한 기술과 융합이 가능해 더욱 발전할 전망을 가지고 있다. 그러나 활용 범위가 갈수록 방대해지지만 현재 기술력으론 완벽한 보안을 실현하기가 어려운 것이 현실이다. 그리고 해킹의 대부분 직접적인 피해 당사자인 소비자들은 스마트홈이 주는 편의에 대해서만 알 뿐 보안 위협요소에는 잘 알지 못한다. 스마트홈의 보급이 빨라지고 있지만 정부 및 제조사에서 아직 스마트홈 보안에 관련한 홍보 및 교육이 따라가지 못하기 때문이다. 이러한 점을 보완하기 위해 본 논문에선 스마트홈의 보안 실태와 보안 요구사항에 대해서 다양한 방안을 살펴보고자 한다.

Exposure of personal information that is held by hacking accident near the company has led to severe water level. And, it has changed security threat elements generated according to businessenterprise. Therefore, in this paper, I looked at security threat elements and proposed the way of appropriate information security consulting according type of company. First, In the financial and insurance industries, and should not have been compromised by a worm virus infection due to lack of awareness inside of members, by collectively apply in the same way the internal security standards of the organization to members, the risk of customer information. It shall be provided in advance that the security accident occurs due to a higher job group. Therefore, information security consulting method based on people and information is applied. Secondly, in industry of company, to perform consulting information security based on the attributes of the case industry groups.

Speedy development has been witnessed in communication technologies and the adoption of the Internet across the world. Information dissemination is the primary goal of these technologies. One of the rapidly developing nations in the Middle East is Saudi Arabia, where the use of communication technologies, including mobile and Internet, has drastically risen in recent times. These advancements are relatively new to the region when contrasted to developed nations. Thus, offenses arising from the adoption of these technologies may be new to Saudi Arabians. This study examines cyber security awareness among Saudi Arabian citizens in distinct settings. A comparison is made between the cybersecurity policy guidelines adopted in Saudi Arabia and three other nations. This review will explore distinct essential elements and approaches to mitigating cybercrimes in the United States, Singapore, and India. Following an analysis of the current cybersecurity framework in Saudi Arabia, suggestions for improvement are determined from the overall findings. A key objective is enhancing the nationwide focus on efficient safety and security systems. While the participants display a clear knowledge of IT, the surveyed literature shows limited awareness of the risks related to cyber security practices and the role of government in promoting data safety across the Internet. As the findings indicate, proper frameworks regarding cyber security need to be considered to ensure that associated threats are mitigated as Saudi Arabia aspires to become an efficient smart nation.
