In line with the advanced wireless communication technology, M2M (Machine-to-Machine) communication has drawn attention in industry. M2M communication features are installed and operated in the fields where human accessibility is highly limited such as disaster, safety, construction, health and welfare, climate, environment, logistics, culture, defense, medical care, agriculture and stockbreeding. In M2M communication, machine replaces people for automatic communication and countermeasures as part of unmanned information management and machine operation. Wireless M2M inter-device communication is likely to be exposed to intruders' attacks, causing security issues, which warrants proper security measures including cross-authentication of whether devices are legitimate. Therefore, research on multiple security protocols has been conducted. The present study applied SessionKey, HashFunction and Nonce to address security issues in M2M communication and proposed a safe protocol with reinforced security properties. Notably, unlike most previous studies arguing for the security of certain protocols based on mathematical theorem proving, the present study used the formal verification with Casper/FDR to prove the safety of the proposed protocol. In short, the proposed protocol was found to be safe and secure.

The auto industry has significantly evolved to the extent that much attention is paid to M2M (Machine-to-Machine) communication. In M2M communication which was first used in meteorology, environment, logistics, national defense, agriculture and stockbreeding, devices automatically communicate and operate in accordance with varying situations. M2M system is applied to vehicles, specifically to device-to-device communication inside cars, vehicle-to-vehicle communication, communication between vehicles and traffic facilities and that between vehicles and surroundings. However, communication systems are characterized by potential intruders' attacks in transmission sections, which may cause serious safety problems if vehicles' operating system, control system and engine control parts are attacked. Thus, device-to-device secure communication has been actively researched. With a view to secure communication between vehicular devices, the present study drew on hash functions and complex mathematical formulae to design a protocol, which was then tested with Casper/FDR, a tool for formal verification of protocols. In brief, the proposed protocol proved to operate safely against a range of attacks and be effective in practical application.

In parallel with evolving information communication technology, M2M(Machine-to-Machine) industry has implemented multi-functional and high-performance systems, and made great strides with IoT(Internet of Things) and IoE(Internet of Everything). Authentication, confidentiality, anonymity, non-repudiation, data reliability, connectionless and traceability are prerequisites for communication security. Yet, the wireless transmission section in M2M communication is exposed to intruders' attacks. Any security issues attributable to M2M wireless communication protocols may lead to serious concerns including system faults, information leakage and privacy challenges. Therefore, mutual authentication and security are key components of protocol design. Recently, secure communication protocols have been regarded as highly important and explored as such. The present paper draws on hash function, random numbers, secret keys and session keys to design a secure communication protocol. Also, this paper tests the proposed protocol with a formal verification tool, Casper/FDR, to demonstrate its security against a range of intruders' attacks. In brief, the proposed protocol meets the security requirements, addressing the challenges without any problems.

최근 IT기술의 발전과 더불어 보안의 중요성이 부각되면서 Pin Number, Password, Pattern Recognition 등 인증 방식에 대한 연구가 진행되고 있지만 위와 같은 One-factor 인증 시스템에는 "Shoulder Attack"과 같은 사용자 레벨에서의 보안공격에 취약하다. 위와 같은 문제점을 해결하기 위하여 'Google E-mail' 등 일부 강화된 보안이 필요한 시스템에서는 추가 모듈을 이용한 Two-factor 인증 시스템을 적용하여 보안을 제공하고 있지만 사용상의 번거로움과 복잡성으로 인해 고도의 보안 기술의 적용을 받지 못하는 등 많은 제약사항이 남아있다. 본 논문에서는 위 와 같은 One-factor 시스템의 취약점을 파악하여 그에 따라 보안 인증 절차를 향상시키기 위해 암호화와 인증 방법으로 지문인식을 사용하여 Multi-level 인증 시스템을 제안한다. 본 시스템은 Send 디비이스를 구현한 아두이노를 통해 M2M 서비스를 수행하며, 암호와 지문 정보를 아두이노 디바이스에 저장하여 두 가지의 신뢰적인 정보를 바탕으로 인증하는 시스템이다. 아두이노를 이용하여 디바이스 분리를 통한 사용자 레벨에서의 보안을 강하고 지문인식을 통해 불편함과 복잡성을 간소화하였다.

Machine-to-Machine (M2M) communication provides each component (machine) with access to Internet, evolving into the IoT technology. IoT is a trend where numbers of devices provide the communication service, using the Internet protocol. As spreading the concept of IoT(Internet of Things), various objects become home information sources. According to the wide spread of various devices, it is difficult to access data on the devices with unified manners. Under this environment, security is a critical element to create various types of application and service. In this paper propose the inter-device authentication and Centralized Remote Security Provisioning framework in Open M2M environment. The results of previous studies in this task is carried out by protecting it with the latest information on M2M / IoT and designed to provide the ultimate goal of future M2M / IoT optimized platform that can be integrated M2M / IoT service security and security model presents the information.

5G networks are rapidly expanding. Simultaneously, the need for a testbed-not a commercial network-is increasing to verify aspects such as 5G network security vulnerabilities. Open-source projects in 4G networks already exist and are implemented similarly in commercial networks. Due to the compatibilty between 5G and 4G networks, 5G networks are being developed and implemented as open-source projects on the basis of 4G networks. In this study, we review the development trends of 5G open-source projects and simulators that can be used for 5G research.

Due to the dramatic advancement of IoT (Internet of Things), it is expected that tens of billions of IoT devices will be connected by the year 2024. Furthermore, as IoT technologies evolves, the security management in IoT platforms has become a critical issue. For example, there are interworking problems between heterogeneous IoT platforms caused by differences from communication protocols, security policies, etc. in each platform. In addition, unsecured interworking can cause major security issues including the information leakage. In this paper, in order to solve these problems, a security interworking architecture is proposed and implemented in both FIWARE and oneM2M, which are representative IoT platforms. First, the security architecture of FIWARE is analyzed and implemented, and then the security framework based on OAuth 2.0 is developed on Mobius platform. Finally, in order to validate the proposed security interworking architecture, a LED (Light-Emitting Diode) example, where the LED is controlled by only authorized users, is developed. The proposed architecture can be extended to the diverse IoT platforms and devices.

IT관련 제품(데스크톱, 노트북, 스마트폰 등)과 자동차, 선박, 자판기 등 기계(Machine)관련 제품과의 융합이 이뤄지고 있으며 각 장비간의 통합 융합으로 변화됨에 따라 네트워크 시스템과 S/W에 대한 보호가 더욱 어려워지고 있는 상황이다. 이러한 문제는 산업계 내에서 다양한 그룹의 사용자들이 다양한 장비를 사용하므로 더 복잡해지며, 결국에는 수많은 기계장치의 사용자 수준에 따라 다른 수준의 보안이 필요하게 된다. 본 논문에서는 차세대 이동통신의 한분야인 M2M(Mahcine to Machine) 통신에 대한 동향 소개와 M2M의 보안 위협요소 분석을 통한 키관리 기법과 Threshold 암호 기법을 소개한다.
