An Attribute-Based Access Control Model for Internet of Things Using Hyperledger Fabric Blockchain

The Internet of Things (IoT) is emerging from its infancy and establishing itself as a component the future Internet. However, ability to manage huge number IoT devices one technical challenges. To implement access control, traditional schemes typically rely on trusted central organization. Traditional centralized control systems lead shortcomings single point failure, low overall system efficiency, ethical privacy issues. overcome such challenges, an attribute-based model using Hyperledger Fabric blockchain (ABAC-HLFBC) proposed in this paper. By adopting ABAC, it no longer create lists (ACLs) or assign roles all users. Instead, ABAC grants based attributes presented by target. No permitted unless he/she possesses sufficient that correspond policy. Raft consensus mechanism has been used verify transaction because demanding feature for faster less complicated comparison Kafka ordering service. evaluate model, tested against most recent previous work, called fabric-iot model. evaluated two parts. first part tests cost time client test program written Golang. second latency throughput Caliper benchmark tool.
