Smart healthcare systems, a convergent industry based on information and communications technologies (ICT), has emerged from personal health management to remote medical treatment as a distinguished industry. The smart healthcare environment provides technology to deliver vital information, such as pulse rate, body temperature, health status, and so on, from wearable devices to the hospital network where the physician is located. However, since it deals with the patient's personal medical information, there is a security issue for personal information management, and the system may be vulnerable to cyber-attacks in wireless networks. Therefore, this study focuses on a key-development and device-management system to generate keys in the smart environment to safely manage devices. The protocol is designed to provide safe communications with the generated key and to manage the devices, as well as the generated key. The security level is analyzed against attack methods that may occur in a healthcare environment, and it was compared with existing key methods and coding capabilities. In the performance evaluation, we analyze the security against attacks occurring in a smart healthcare environment, and the security and efficiency of the existing key encryption method, and we confirmed an improvement of about 15%, compared to the existing cipher systems.

At the core of future medicine is the realization of Precision Medicine centered on individuals. For this, we need to have an open ecosystem that can view, manage and distribute healthcare data anytime, anywhere. However, since healthcare data deals with sensitive personal information, a significant level of reliability and security are required at the same time. In order to solve this problem, the healthcare industry is paying attention to the blockchain technology. Unlike the existing information communication infrastructure, which stores and manages transaction information in a central server, the block chain technology is a distributed operating network in which a data is distributed and managed by all users participating in the network. In this study, we not only discuss the technical and legal aspects necessary for demonstration of healthcare data distribution using blockchain technology but also introduce KOREN SDI Network-based Healthcare Big Data Distribution Demonstration Study. In addition, we discuss policy strategies for activating blockchain technology in healthcare.

In this paper, we proposed an iris-based authentication for smart healthcare service in secure telemedicine system. The medical and healthcare information's are very important data in telemedicine system from privacy information. thus, the proposed system provides a secure and convenient authentication method than the traditional ID/PW authentication method to a telemedicine system for age-related chronic diseases. When considering the peculiarities of the use of age-related chronic diseases convenience and healthcare environments, the proposed approach is difficult to secure than traditional ID/PW authentication method with the appropriate means to easily change when stolen or lost to others. In addition, the telemedicine system for the smart healthcare services is one of the types of privacy sensitive medical and health data. it is very important security needs in telemedicine system. Thus we protocol are offer high confidentiality and integrity than existing ID/PW method.

Nowadays u-healthcare which is very sensitive to the character of user's information among other ubiquitous computing field is popular in medical field. u-healthcare deals extremely personal information including personal health/medical information so it is exposed to various weaknees and threats in the part of security and privacy. In this paper, RFID based patient's information protecting protocol that prevents to damage the information using his or her mobile unit illegally by others is proposed. The protocol separates the authority of hospital(doctor, nurse, pharmacy) to access to patient's information by level of access authority of hospital which is registered to management server and makes the hospital do the minimum task. Specially, the management server which plays the role of gateway makes access permission key periodically not to be accessed by others about unauthorized information except authorized information and improves patient's certification and management.

최근 IoT 기술이 홈케어, 헬스케어, 자동차, 교통, 농업, 제조업 등 다양한 분야에 적용되면서 신성장 동력의 핵심으로 IoT 서비스를 제공하거나 IoT 환경을 자체적으로 구축하여 산업현장에 도입하려는 기업이나 기관이 증가하고 있다. 그러나 IoT 환경은 인터넷을 통해 현실세계와 IoT 디바이스가 직접 연결되는 특성으로 인해서 IoT 보안의 중요성이 더욱 강조되고 있으며 IoT를 이용한 보안 사고 사례 및 취약점이 지속적으로 발표되면서 IoT 보안 위험 또한 계속 증가되고 있다. 이렇게 IoT 환경에는 많은 취약점과 보안 위협이 존재하기에 IoT 제품의 최초 설계/개발 단계부터 배포/설치/구성 단계, 운영/관리/폐기 단계까지 IoT 제품 및 서비스의 각 단계별로 보안 요구사항과 가이드라인을 적용하여 보안을 내재화하고 IoT 제품 및 서비스를 도입하는 사용자 입장에서 IoT 보안에 대해서 관심을 가지고 스스로 확인 할 수 있도록 보안 점검 기준이 필요하다. 본고에서는 IoT 디바이스의 특성과 보안 요구사항에 따른 보안 원칙 및 보안 가이드를 살펴보고 IoT 기술을 산업현장에 적용하고자 하는 기관/기업에 적용 가능한 IoT 디바이스의 보안 점검 기준을 제시한다.

The security of medical information need continued research about steady and flexible security model because of privacy of patient's as well as directly relation in the patient's life. In particular, u-healthcare environment is need flexible and detailed access control by variety changes of context. Control model analyzed relation of resource and authority, and analyzed authority about all accessible resource from access point using K2BASE. The context-based access control model can change flexibly authority change and role, and can obtain resource of authority granted and meaningly connected resource. As a result, this thesis can apply flexible and adaptive access control model at u-healthcare domain which context change various.

The aging population and worsening lifestyle habits have increased the risk of chronic diseases. This has heightened the importance of preventive healthcare, particularly through personalized health management services based on individual health data. Despite this, the domestic digital healthcare industry remains underdeveloped. Given the need for acceptance from both consumers and providers, this study uses the Analytic Hierarchy Process (AHP) to identify success factors for health management service platforms. AHP evaluates the relative importance of various factors to aid decision-making. Results show that providers prioritize data analysis and platform design, laws and regulations, and data standardization, while consumers prioritize system stability, laws and regulations, and system security. These findings highlight the need for strategies to bridge the expectation gap to effectively promote health management service platforms.

본 논문에서는 다수의 모바일 장치가 협업을 할 수 있는 환경을 제안하고, 이를 기반으로 헬스케어 응용 서비스에 적용함을 보였다. 제안한 협업 환경은 센서와 모바일 장치, 모바일 장치와 모바일 장치, 모바일 장치와 홈 서버의 상호작용을 3가지 타입으로 정의 하였다. 또한 이들간의 정보 교환은 Push와 Pull방식으로 구분하였으며, 다수의 센서로부터 수집된 정보는 보안 정책에 따라 모바일 장치간 정보를 교환하거나 홈 서버에게 전달한다. 보안 정책은 개인 의료 처방과 예방을 위한 개인 정보와 주변 환경에 관련된 공개 정보로 나누어 관리하여 협업 환경에 적용하였다. 이는 개인 사용자마다 상이한 서비스를 제공하는데 기반이 된다. 이를 위한 구현 기술로는 적시성을 보장하는 TMO 스킴을 이용하여 컴포넌트를 설계 및 구현하였으며, 이들간의 상호작용은 TMOSM을 사용하였다.

In this paper, we propose a secure and efficient RFID-based patient authentication protocol to not only authenticate patients' authenticity but also protect patients' personal medical informations for u-Healthcare environments. Since the proposed RFID-based patient authentication protocol provides strong security and efficiency, it can be used practically for patient authentication and personal medical information protection on the high technology medical environments such as u-Hospital and u-Healthcare.
