WebSep 5, 2024 · Abstract: The publication of the pivotal state machine replication protocol PBFT laid the foundation for a body of BFT protocols. We introduce a probabilistic model for evaluating BFT protocols in the presence of dynamic link and crash failures. The model is derived from the communication pattern, facilitating an adaptation to other protocols. WebApr 11, 2024 · This paper mainly summarizes three aspects of information security: Internet of Things (IoT) authentication technology, Internet of Vehicles (IoV) trust management, and IoV privacy protection. Firstly, in an industrial IoT environment, when a user wants to securely access data from IoT sensors in real-time, they may face network attacks due to …

WebSep 8, 2024 · In this work, we propose BMS (Blockchain/BFT Membership Service) offering a secure and dynamic reconfiguration service for BFT and blockchain systems, preventing long-range and similar attacks. In particular: (1) we propose a root BMS for permissioned blockchains, implemented as an Ethereum smart contract and evaluate it reconfiguring … Webour dynamic switching approach resolves these drawbacks to improve reliability and performance. In this paper, we propose an adaptive abortable BFT system, called ADAPT. launches a BFT protocol from a set of candidate ones (any existing protocol). Once the system conditions change (i.e., an event), ADAPT aborts the running
