Recently, emerging the blockchain and smart contract technology has attracted significant scientific interest in research areas like authentication and access control processes. In the context of authentication and access control, blockchain can offer greater data and rule confidentiality and integrity, as well as increasing the availability of the system by removing the single point of failure in the procedure. To categorize and find the most important open problems in this research area, having a comprehensive review is crucial. To the best of our knowledge, for the first time in this survey, we aim to describe the current state of the art in deploying blockchain and smart contracts specifically in authentication and access control. Following an introduction to AAC and blockchain technology, we present a brief background of distributed ledger technology, access control and authentication. To offer a clearer understanding of the state of the art, we propose taxonomy to categorize the existing methods based on their type, application environment and their justification for exploiting blockchain. For the conclusion of the paper, we examined the advantages and disadvantages of the proposed method in different contexts like security, resource consumption and privacy. Also we discussed about the future work.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"3 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":"123489807","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}

Existing Public Key Infrastructures (PKIs) are capable of certifying digital identities but do not provide solutions to immutably store signatures, and the process of certification is often not transparent. In this work we propose Veritaa, a Distributed Public Key Infrastructure and Signature Store (DPKISS). The major innovation of Veritaa is the Graph of Trust, a directed graph that uses relations between identity claims to certify the identities and stores signed relations to digital document identifiers. The distributed architecture of Veritaa and the Graph of Trust enables a transparent certification process. To ensure non-repudiation and immutability of all actions that have been signed on the Graph of Trust, an application specific Distributed Ledger Technology (DLT) is used as secure storage. In this work a reference implementation of the proposed architecture was designed and implemented. Furthermore, a testbed was created and used for the evaluation of Veritaa. The evaluation of Veritaa shows the benefits and the high performance of the proposed architecture.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"14 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":"131756682","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}

While many blockchain wallets execute their core program code off-chain, some wallets implement core functionality on-chain as smart contracts with the intent to increase trust and security by using transparent and verifiable execution.In this work, we investigate smart contracts for wallets with regard to the functionality that makes use of cryptographically secured blockchain technology. We focus on wallet contracts deployed on Ethereum, as it is the most prominent platform for tokens and smart contracts with readily available data. We aim at a better understanding of this frequently deployed group of smart contracts by analyzing characteristics of wallet contracts and grouping them into six types. To this end, we present approaches to identify wallet contracts by analyzing source code, bytecode, and execution traces extracted from transaction data. Moreover, we investigate usage scenarios and patterns. From the derived data, we extract blueprints for wallets and compile a ground truth. We provide numbers and temporal perspectives regarding the creation and use of wallets.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"47 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":"134633063","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}

Having service providers continue to offer their centric solutions is inefficient in terms of duplication, has serious security lacunae and is cumbersome to the users. The self-sovereign Identity concept, which includes the individual’s consolidated digital identity and verified attributes, enables the users of data to exert their ownership and gain insights from their data’s usage. The authentication and verification of digital identity is essential to achieve the privacy and security of distributed digital identities. In this paper, we provide a coherent view of the central concepts of self-sovereign Identity, including the components of identity proofing and authentication solutions for different self-sovereign Identity solutions. We discussed an overview of Identity management approaches, introducing an architecture overview as well as the relevant actors in such a system and blockchain technology as solution for distributed user-centric identity. Finally, we discuss the existing solutions and point out the research gaps and elaborate challenges and trade-offs towards building a complete identity management system.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"39 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":"129396245","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 advent of blockchain-based cryptocurrencies such as Ethereum provides unprecedented characteristics. On one hand, the pseudonymity of the blockchain allows criminals to hide their actual identities, which is an appealing feature for conducting malicious activities. On the other hand, the public data of blockchain sets forth the opportunity for comprehensive forensic analysis. In this paper, we present a novel framework to identify malicious entities in the Ethereum blockchain network. The proposed framework composes of an efficient method for extracting a set of features from the Ethereum blockchain data to represent transactional behavior of entities. Our proposed solutions for detecting malicious entities employ variations of Logistic Regression, Support Vector Machine, Random Forest, and other ensemble methods such as Stacking and AdaBoost Classifier. The ensemble methods show high performance with F1 score of 0.996 in average. The results also imply that the proposed method of feature extraction is fairly efficient in presenting the network characteristics.","PeriodicalId":315392,"journal":{"name":"2020 2nd Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)","volume":"31 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":"128884229","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}
