Vulnerabilities on Hyperledger Fabric
Pervasive and Mobile Computing, 2019Abstract In this paper, we have precisely analysed Hyperledger Fabric and pointed out two security limitations with possible solutions. First, the identity of an endorser is known to all members within a channel, which opens a gateway for DoS attack on endorsers in order to either block transaction pertaining to a client, or to degrade network ...

Secure Drone Identification with Hyperledger Iroha
Proceedings of the 11th ACM Symposium on Design and Analysis of Intelligent Vehicular Networks and Applications, 2021Interet-of-Things (IoT) devices such as drones are becoming more prevalent, but still have blatant security issues. DRIP is a newly proposed protocol for drones that aims to enable users to securely identify drones and trust in messages sent by them. However, some implementation details, such as registries, are yet to be determined.

Transparent Logging with Hyperledger Fabric
2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC), 2019Today a massive amount of data is used for machine learning (ML) and artificial intelligence (AI) to derive knowledge about the world and do automated decision making. All this data contains personal and/or sensitive data, and thus privacy is becoming more and more important.

Transactive Energy on Hyperledger Fabric
2019 Sixth International Conference on Internet of Things: Systems, Management and Security (IOTSMS), 2019As home solar power generation continues to gain popularity, trading excess power within the community is the next logical step. Locally generated power can enrich communities, cut down on transmission losses and provide some measure of energy security. In order to facilitate intra-neighborhood energy transactions, we propose a model that leverages the
