Handling Node Expulsion and Replacement

Identifying Compromised Nodes

• The network continuously monitors nodes for any signs of compromise or malicious behavior.

• If a node is identified as a threat, it is marked for removal from its clusters.

Seamless Replacement

• A replacement node is selected to take the place of the banned node.

• The system redistributes key shares to maintain the security and functionality of the clusters without interruption.

Node Expulsion Process

Security Protocol

1. Detection Phase

   • Continuous monitoring of node behavior

   • Automated threat detection systems

   • Regular security audits

   • Anomaly detection algorithms

2. Expulsion Process

   • Immediate isolation of compromised node

   • Revocation of access credentials

   • Secure removal from cluster configuration

   • Notification to network administrators

3. Replacement Workflow

   • Selection of qualified replacement node

   • Verification of new node integrity

   • Integration into existing cluster

   • Distribution of new key shares

4. Recovery Steps

   • Validation of cluster stability

   • Security parameter updates

   • System integrity checks

   • Documentation of incident
