This paper provides a new perspective for reducing digital identity management systems (DIMS) to two mappings, the core operations on the mappings, and the trust model built around the mappings. Using this two-mapping view, we derive criteria for determining whether a DIMS solution is self-sovereign. We also compare decentralized identity management solutions with the traditional centralized identity management solutions. From the comparison and analysis, we have the following findings. The differences between decentralized and centralized solutions stem from the trust model differences which dictate storage scheme differences, and therefore other operation-level differences. With a more trustless trust model and storage scheme, current decentralized solutions can be promising candidates for self-sovereign DIMS. Design considerations and certain limitations of the current decentralized solutions are analyzed based on the two-mapping view as well, which can provide useful directions to further study.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122184086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since IoT systems often handle private information, it is essential to enforce appropriate access control to prevent unauthorized access. However, conventional access control schemes in which access rights are stored in a centralized server are prone to load concentration and a single point of failure. Although distributed access control schemes leveraging blockchain technologies have been proposed to deal with such problems, they inherit the drawbacks of the blockchain technologies, such as high transaction fee and low throughput. This paper proposes a novel access control framework based on IOTA, an emerging distributed ledger technology which enables free micro transactions with high throughput. This framework provides scalable and fine-grained access control by encrypting access rights using the Ciphertext-Policy Attribute-Based Encryption (CP-ABE) technology and storing them on the distributed ledger of IOTA, called Tangle.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124039340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In parallel, the increasing adoption of electric vehicles and the development of vehicle-to-grid (V2G) technology open new ways to store, transport and deliver renewable energy. V2G-enabled cars could contribute to the flexibility of peer-to-peer energy marketplaces. Our physical demonstrator illustrates the benefits of V2G-enabled vehicles in the context of local energy marketplaces in terms of economical gain, overall power balancing and consumed renewable energy rate. The demonstrator is composed of smart contracts implementing such marketplace running on a local Ethereum blockchain deployed on Raspberry Pis, autonomous agents simulating the energy consumption and production behavior of 4 households as well as their buying/selling behavior, and finally a V2G car whose behavior is controlled by a user through a tablet.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133591888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The building sector accounts for about 40% of global energy consumption and 30% of GHG emissions. This sector must reduce its energy consumption by at least 50% by shifting to hyper-efficient systems and renewable energy to meet the climate change mitigation goal. Certified green buildings are responsible for about 40% of the office markets in the U. S. and utilize the types of strategies that should be implemented by all new construction and major renovations. Certified green buildings, although highly effective in reducing greenhouse gas emissions, are generally considered to be an expensive solution to this problem. There is excellent potential for the construction sector to employ a blockchain framework of measurement, report, and verification (MRV) towards building energy performance (BEP) to enable certified green buildings to earn carbon credits based on their exceptional energy performance. Blockchain technology eliminates the need for intermediaries to validate the data and builds up a reliable, immutable, traceable energy monitoring system. The goal of this paper is to present a new blockchain digital MRV architecture for existing BEP and a prototype of its application.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116686072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smart monitoring, which enables the detection and prevention of road traffic accidents, is one promising application of the smart city concept. The deployment of three-dimensional (3D) image sensor networks formed by light detection and ranging (LIDAR) devices interconnected via a network is a key enabler for smart monitoring. Data collected by image sensor networks for smart monitoring are sensitive because the usage of the data is often related to public safety or law enforcement. Managing sensor data using the blockchain technology is one way to address these sensitivity concerns, as a blockchain network helps prevent data from being tampered with even by the administrators of the system. However, prior works have not considered how to handle streaming data such as image sensor data generated by LIDAR devices in real-time, which means there is a risk of overflow in the network if the data are handled frame by frame. In response to this issue, we propose a blockchain framework for real-time monitoring in a smart city using image sensor networks. Our key concept with this framework is to aggregate hash values converted from multiple frames of image sensor data into one hash value. The proposed framework reduces the number of data ‘writes’ on a blockchain network, thus preventing any overflow. Our framework also enables the estimation of the optimal number of aggregated hash values that minimizes delay while avoiding overflow. Measurements taken in actual environments using a real-world LIDAR dataset demonstrated the effectiveness of the proposed framework.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122336015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
