However, a serious underlying problem still exists in the blockchain system - data bloating. In the blockchain system, each (full) node must store the full data set in blockchain history, incurring significant storage pressure in the initial synchronization process and the following maintenance of the blockchain system. Data bloating is a challenging problem to be confronted in the immediate future of blockchain. To address this problem, in this paper, we introduce the BC-Store framework that deploys a data accessing model on an IPFS-cluster system to classify the hot and cold blockchain data. The hot data are stored in the local cache, whereas the cold data are stored in the IPFS cluster, thereby substantially shortening the blockchain initial synchronization time and saving a considerable amount of data storage. Empirical experimentation shows that our framework can reduce the local storage size from over 265GB to 4GB with a hit ratio of 77% for Bitcoin without significant performance degradation with the whole data shared in an IPFS cluster.","PeriodicalId":145384,"journal":{"name":"Proceedings of the 2nd International Electronics Communication Conference","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123208797","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}

D2D technology can potentially increase the network capacity by offloading network traffic in a distributed manner. However, there are also new security challenges such as free-riding attack prevention, device anonymity protection and end-to-end data secrecy. Also, since there are many mobile devices which have limited computational resources in 5G cellular network, there is a need to develop a lightweight authentication protocol which addresses all these security requirements with low computational overhead. In this paper, we propose a lightweight D2D authentication and key agreement protocol based on elliptic curve cryptography (ECC). Specifically, our proposed scheme makes use of the elliptic curve digital signature algorithm (ECDSA), elliptic curve Diffie-Hellman (ECDH) and authenticated encryption with associate data (AEAD) to provide secure device discovery, mutual authentication, key agreement and data transmission for all 5G D2D devices. Our scheme is computationally lightweight to be supported in any resource-constrained 5G devices, and it can resist several active and passive protocol attacks including eavesdropping, replay attack, man-in-the-middle attack and free-riding attack. We analyze the security of our protocol with Scyther to show our scheme is resistant to these attacks. Finally, performance evaluation shows our scheme is efficient for both UEs and CN with rationally low computational costs.","PeriodicalId":145384,"journal":{"name":"Proceedings of the 2nd International Electronics Communication Conference","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132529519","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}

These connected nodes form complex ecosystems encompassing various technologies that collaborate to offer millions of users distributed, decentralized, secure, and read-only data stores. With the proliferation of various private and public platforms and applications that are built on top of blockchain technology, rich sources of several types of simple or complex datasets have been created. Consequently, new requirements for managing these rich data sources, integrating them with their hosting environment, and making them discoverable have emerged. Fulfilling these requirements calls for extending the architecture of current blockchain systems by adding different layers that offer dedicated services for handling the data and allowing for integrating the blockchain-based platforms and applications with other systems, including Web-based applications. In this paper, we present a novel approach aiming at extending the architecture of current blockchain systems by adding new service layers for processing the data and offering new services to provide a bridge between blockchain systems and Web-based external applications enabling them to query, retrieve, and access the datasets managed by robust permission-based access control.","PeriodicalId":145384,"journal":{"name":"Proceedings of the 2nd International Electronics Communication Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133794850","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}

Whereas parties can forfeit the Letter-of-Credit by someone with vast experience and expertise in finance commerce laws, and international laws and business processes. In this research, we aspire to come up with an option of incorporating NFC-enabled mobile application into Letter-of-credit. The application is powered by blockchain technology and would be crucial in helping the recipient of the Letter-of-credit to achieve easy verification of the legitimacy of the document.

However, there are some limitations when storing large files or documents on the blockchain. In order to meet the requirements of storing relatively large data, a decentralized storage medium is produced. IPFS is a distributed file system which is content-addressable. It works very similar to the blockchain network. There are some attempts which take advantage of the blockchain concept and IPFS to design new approaches. Unfortunately, there are some inefficiencies in sharing data using the combination of IPFS and blockchain. In this paper, we proposed a secure file sharing system that brings a distributed access control and group key management by the adoption of the IPFS proxy. The IPFS proxy which plays an important role in the design is adopted to take responsibility for the control policies. The combination of the IPFS server and the blockchain network with the adoption of the IPFS proxy make a secure file sharing system which the members on the system can create new groups or join different groups by their own choice. Although there is no access control mechanism in IPFS server and blockchain network, the secure file sharing system manages the access control policies. The members access files only belong to the group they authorized.","PeriodicalId":145384,"journal":{"name":"Proceedings of the 2nd International Electronics Communication Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126988214","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}

With the advancement of blockchain, it has been concerned in some studies that auditing could be significantly impacted and eventually replaced. Meanwhile, another viewpoint argues that blockchain technology would push the existing auditing industry to a new direction rather than eliminating the need for auditing in the immediate future. This discussion can hardly be settled without evaluation, however, studies exploring how blockchain technology can be employed in auditing practice or how continuous auditing can be conducted using blockchain technology are limited. This paper analyses the impact of blockchain features on existing audit processes and discusses the possibility of applying blockchain characteristics including immutability, distributed ledger, real-time settlement to the auditing domain. Based on the systematic analysis, this study proposes a conceptual model for blockchain-based auditing information system, which provides solutions to employ blockchain technology in auditing profession, significantly improving the efficiency and effectiveness of auditing and promoting the transformation of the auditing paradigm to real-time, continuous and intelligent auditing.","PeriodicalId":145384,"journal":{"name":"Proceedings of the 2nd International Electronics Communication Conference","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124300612","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}

However, the redundant features and the sparse samples of fatal attacks in VANETs datasets cause the heavy time-consumption and imbalanced problems respectively. In this paper, a feature selection algorithm based on a many-objective optimization algorithm (FS-MOEA) is proposed for IDSs in VANETs, in which Non-dominant Sorting Genetic Algorithm-III (NSGA-III) serves as the many-objective evolutionary algorithm. Two improvements, called Bias and Weighted (B&W) niche-preservation and Analytic Hierarchy Process (AHP) prioritizing, are further designed in FS-MOEA. B&W niche-preservation is used to counterbalance the imbalanced problem among the different classes of datasets by assigning rare classes higher priorities in the niching selection process. AHP prioritizing is employed to search the optimal feature subset from the non-dominant feature subsets in the Pareto Front of FS-MOEA. Experimental results show that the proposed FS-MOEA can not only improve the performance of IDSs in VANETs by decreasing the redundancy and irrelevances of features but also alleviate the negative impact of the imbalanced problem.","PeriodicalId":145384,"journal":{"name":"Proceedings of the 2nd International Electronics Communication Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129106072","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}
