The uses of drones are increasing despite the fact that many of us are still skeptical. In the near future, the data that will be created and used by them will be very voluminous, hence the need to find an architecture that allows good identity management and access control in a decentralized way while guaranteeing security and privacy. In this article, we propose an architecture using hyperledger fabric blockchain platform which will manage the identity in a secure way starting with the registration of the drones on the network then an access control thanks to Public Key Infrastructure (PKI) and membership service provider (MSP) to enable decision-making within the system.

오늘날 기업에게 기술력과 디자인은 무한경쟁시대에서 요구되는 전제조건으로 인식되고 있다. 대부분의 기업 특히 도자기기업에서는 실용적이거나 또는 제품의 미적인 부분을 개별적으로 다루고 있는 것이 사실이다. 이에 따라 기업의 아이덴티티를 형성하기에 어려움을 겪게 된다. 그러나 독일의 로젠탈사의 경우 이미 1900년대 중반부터 디자인과 더불어 독창적인 프로세스를 통하여 기업의 아이덴티티를 확립하였으며, 독창적인 디자인 매니지먼트를 통해 제품을 생산하는 기업으로 평가되고 있다. 특히 로젠탈의 아이덴티티는 디자인 결과물이 아니라 개발 프로세스를 검증하는 "Jury System"과 독립브랜드 마케팅 그리고 순수 예술가들과의 콜라보내이션과 같은 실험정신에 의해 더욱 독창적으로 형성되고 있다. 특히 디자인 개발에 예술가들이 참여함으로써 이 기업의 도자기 제품은 단순히 생활도자 제품만이 아니라 감상과 수집을 위한 명품으로 평가되고 있다. 또한 로젠탈은 기업 아이덴티티가 단순히 제품에 의해 생성되는 것이 아니라, 디자인 경영기술을 통한 기업 내 외적 요인에 의해 완성될 수 있음을 보여주고 있다.

As a cornerstone of the next generation air traffic management (ATM), automatic dependent surveillance-broadcast (ADS-B) system can provide continual broadcast of aircraft position, identity, velocity and other messages over unencrypted data links to generate a common situational awareness picture for ATM. However, since ADS-B messages are unauthenticated, it is easy to insert fake aircrafts into the system via spoofing or insertion of false messages. Unfortunately, the authentication for ADS-B messages has not yet been well studied. In this paper, we propose an efficient broadcast authentication scheme with batch verification for ADS-B messages which employs an identity-based signature (IBS). Security analysis indicates that our scheme can achieve integrity and authenticity of ADS-B messages, batch verification, and resilience to key leakage. Performance evaluation demonstrates that our scheme is computationally efficient for the typical avionics devices with limited resources, and it has low communication overhead well suitable for low-bandwidth ADS-B data link.

Recently, the interior design of electric home appliance stores requires comprehensive image management with systemic marketing strategies and consistence in order to attract consumers to purchase products. However, the environment of domestic electric home appliance stores is complex and confused by indiscreet design factors and operation. Despite of the fact that company costs a lot of money to manage each store, consumers are not provided with selling environment with high quality. On the other hand, it is inevitable to compete with foreign specialized stores and discount malls due to opening distribution market. Besides, company has faced to attract customers with distinct strategies in order to survive in various competition system. In this sense, in store environment, there should be consistent image in interior design of the store based on management ideology of the company for the successful management of electric home appliance stores. The purpose of this research is to investigate and analyze the case of Samsung Electronics's electric home appliance stores among domestic electric home appliance stores that is applied with Store Identity Program (hereafter SIP) and to suggest solutions for the problems. Therefore, it is purposed to use as references for the stores that has the similar interior design plan. The result of this study is to upgrade the store image through providing basic data about role of data and distinct factors for competitive design as a part of Store Identity Strategy. Furthermore, it can be important data to optimize the profits and to make positive space for both consumer and company as company and products are credible with mental satisfaction of consumers if there is enough study on SIP and process and symbol of company and products to consumers, enough recognition and improvement on problems.

Routing in mobile ad hoc networks is performed in a distributed fashion where each node acts as host and router, such that it forwards incoming packets for others without relying on a dedicated router. Nodes are mostly resource constraint and the users are usually inclined to conserve their resources and exhibit selfish behaviour by not contributing in the routing process. The trust and reputation models have been proposed to motivate selfish nodes for cooperation in the packet forwarding process. Nodes having bad trust or reputation are detected and secluded from the network, eventually. However, due to the lack of proper identity management and use of non-persistent identities in ad hoc networks, malicious nodes can pose various threats to these methods. For example, a malicious node can discard the bad reputed identity and enter into the system with another identity afresh, called whitewashing. Similarly, a malicious node may create more than one identity, called Sybil attack, for self-promotion, defame other nodes, and broadcast fake recommendations in the network. These identity-based attacks disrupt the overall detection of the reputation systems. In this paper, we propose a reputation-based scheme that detects selfish nodes and deters identity attacks. We address the issue in such a way that, for normal selfish nodes, it will become no longer advantageous to carry out a whitewash. Sybil attackers are also discouraged (i.e., on a single battery, they may create fewer identities). We design and analyse our rationale via game theory and evaluate our proposed reputation system using NS-2 simulator. The results obtained from the simulation demonstrate that our proposed technique considerably diminishes the throughput and utility of selfish nodes with a single identity and selfish nodes with multiple identities when compared to the benchmark scheme.

This study analyzed a characteristic by types of urban regeneration helping the establishment of urban identity under social condition change. It will be foundation of sustainable urban development with strategy that secures world-wide competitive power. For this, sample cases that established identity from urban regeneration were reviewed about the main subject and the supporting subject in business side and hardware, software, system, and finance in design factors. 4samples each in inheritance intensification type and change creation type were selected and analyzed. The result said it is most effective to establish urban identity when inheritance intensification type is the private-centered for urban regeneration. And it is better to do the project that the main subject and the supporting subject are taken by the private or the private-leading partnership. It is necessary to manage the region and plan events with software design factors more than hardware design factors. In addition, for urban identity, it was found to be desirable to utilize and preserve fully current resources such as historical scenery and activate the communities than making new facilities. On the contrary, the project based on change creation type needs to be under the public management with innovative idea. Also, when it comes to design factors, facilities related to culture and art and community spaces should open and run actively. It is important for the region to improve its image by New design style such as TOD. In software side, it is important to manage the region by monitoring about urban regeneration business and solve social mix and employment problem. On the other hand, in terms of system and administration, both types don't show a difference in urban identity establishment, since it is same that both should make partnership and get a support of subsidy to be most effective.

As people increasingly rely on mobile networks in modern society, mobile communication security is becoming more and more important. In the Long Term Evolution/System Architecture Evolution (LTE/SAE) architecture, the 3rd Generation Partnership (3GPP) team has also developed the improved Evolved Packet System Authentication and Key Agreement (EPS AKA) protocol based on the 3rd Generation Authentication and Key Agreement (3G AKA) protocol in order to provide mutual authentication and secure communication between the user and the network. Unfortunately, the EPS AKA also has several vulnerabilities such as sending the International Mobile Subscriber Identity (IMSI) in plain text (which leads to disclosure of user identity and further causes location and tracing of the user, Mobility Management Entity (MME) attack), man-in-middle attack, etc. Hence, in this paper, we analyze the EPS AKA protocol and point out its deficiencies and then propose an Efficient and Security Enhanced Authentication and Key agreement (ESE-EPS AKA) protocol based on hybrid of Dynamic Pseudonym Mechanism (DPM) and Public Key Infrastructure (PKI) retaining the original framework and the infrastructure of the LTE network. Then, our evaluation proves that the proposed new ESE-EPS AKA protocol is relatively more efficient, secure and satisfies some of the security requirements such as confidentiality, integrity and authentication.

This study puts its purpose on presenting an integral system of representative urban landscapes, public design and colors, in practicing urban design in the context of local identity. An integral design of public design that successfully plans and executes local identity, and changes recognition of integral management of urban design, is suggested as followings. Firstly, when the catchment area is divided in metropolitan area, it should be reset according to the natural environment condition regardless of administrative area system like city and county. It is the method to classify the metropolitan area by researching and analyzing geographical condition, weather condition, soil and vegetation in detail and subclassify it by the visual commonness of natural environment. Secondly, it is necessary to access the urban landscape, public design and urban color from the overall aspect emphasizing the plan for each field and local identity. They should be practiced by the role and category of each field on the basis of consistent design strategy and instruction but the cooperation system is required as a process to reinforce and specify the mutual limit. Thirdly, the artificial structure is constructed through artificial adjustment depending on the urban formation process and the development time point. Therefore, it is necessary to pay attention to the rapid urban development, the change speed and the landscape formation of each age. It is necessary to classify the type of artificial landscape by age and form similarity and separate the area that should be generalized and controlled by entire metropolitan area form the area that should be specialized by basic local government.

Today the corporate environment is changing rapidly in a standpoint of politics, economics, society and technology environment. So corporates need a management strategy in another point of view. As a new menagement strategy it is introduced corporate culture. The corporate culture should be built with the core of CI, in order to be adapted to peripheral circumstances of the company. The purpose of this thesis is to contribute to manage the systematic management of corporate image by inquiring into corporate identity. Through the research of the deluxe hotels in seoul it is tried to find hotel CI-concept. As a result, the knowledge level of hotel managers is a little low and considered simply as the modification of basic elements and development of a visual idenification system. The emphasis must be on the coordination and integration to create a desired coroporate image and to communicate this image created for the target audience in a systematic and unified mannr.
