“…It focuses on the management of access privileges which allow or deny access depending on user context, with access control policies that deny access to the data stored in the network for unauthorized users. To that end they analyzed a previously-studied context data access control scheme based on CP-ABE, included dynamic situations within the scope of context data and proposed an extended access control policy that reflects extended multi-dimensional context attributes [18][19][20][21].…”

With the development of the Internet of Things and big data technology, it was easy to collect personal situation information. The information collected in this way requires the user to support customized services via big data technology. However, traditional situational awareness systems request action through user cognition or provide consistent services for the specific purposes of multiple users. Therefore, this paper proposes a mechanism of Vehicular CPS with situational cognitive function that minimizes direct user intervention for user customization services. In this paper, we designed the system configuration and detailed process based on the scenario of the situation where the user is driving a car. A vector is used to provide a method for determining a dangerous water level by analyzing an abnormal state of a reception threshold with a sensor. The proposed system was analyzed by simulation. By using the authorization step that operates based on the sensor data, we were able to know that the reliability of the user is improved and that the reliable processing of the IoT service is possible. In the future, research for personal authentication and encryption is needed for more secure information processing.

“…Song, YJ et al [2] emphasized the importance of generating new information, i.e., contextual information, by deducing information collected according to the user's situation in the Internet environment of things. In order to protect sensitive information that is sensed in the Internet environment of objects, information access control technique through context awareness is needed.…”

Data collected through devices are stored in a single cloud and processed in Internet of Things (IoT) environment. Because IoT has a limitation of computing and storage space of devices. In order to solve the problem of reliability of centralized system, previous researches have been carried out to link blockchain to the Internet. However, user privacy protection is an indispensable factor for sharing data through the Internet. However, these limitations are not overcome. In this paper, the access control of the user is made flexible and robust through Dynamic Access Control Table (DACT) using the context attribute of IDentity of Things (IDoT). The system proposed in this paper can build a platform to securely share users' power consumption data in the energy cloud. 1

“…It is emerging as a hot topic in various applications such as the Internet of Things and self-driving cars in financial transactions that can reduce virtual currency functions and transaction fees. In addition, various projects are underway in the energy sector and many changes in existing power trading and supply systems are expected when commercialized [4][5][6][7] [8]. Blockchain-based technologies are applied to transaction systems that compensate for solar power production in a "Solar Coin," prosumer trading systems that produce solar energy and trade surplus electricity between neighbors, and electric vehicle charging stations.…”

Recently, the paradigm of the power industry has been digitalization with a focus on renewable energy. With this shift toward the energy-ICT convergence accelerator, there will also be many changes in effect energy policies. In particular, in terms of energy demand management, there will be regional-centric, self-reliant decentralization, and the activation of Distributed Energy Resources (DERs) including renewable energy will result in the deployment of microgrid-type virtual power plants on a region-wide basis. This paper designs a blockchain-based power transaction process in which individuals (producers) can produce and use power themselves or sell the remaining power to others, rather than transmitting and using the developed power from the existing centralized power. 1
