PoAS: Enhanced Consensus Algorithm for Collaborative Blockchain Intrusion Detection System

Signature-based Collaborative Intrusion Detection System (CIDS) deeply depends on the reliability of nodes to produce attack signatures. Each node in the network is responsible to produce a new attack signature to be distributed with other nodes. There is an issue that exists in CIDS highlighted in this paper, it is to maintain trust between the nodes while distributing the attack signatures. Recently, researchers found that blockchain has great...
