Goals 

   Implement a CRDT-based mechanism for distributed trust computation and conflict-free updates during network partition recovery.

CRDTs and Trust Systems​ 

   The thesis reviews CRDT concepts and distributed trust systemsas the foundation for trust propagation.​

Trust Propagation Protocol​ 

   A trust propagation protocol using CRDTs is designed forreliable trust updates in partitioned networks.​

Simulation and Testing​ 

   The protocol is tested in simulated partitioned networkscenarios to measure performance and update accuracy.​

Evaluation Metrics​ 

  Success rate of conflict-free updates and accuracy of trustreconciliation post-recovery are evaluated.​

Main Tasks: Task 1: Review CRDTs and distributed trust systems. Task 2: Design trust propagation protocol using CRDTs. Task 3: Implement protocol in a simulated partitioned network. Task 4: Test trust updates during and after partitions. Task 5: Measure performance degradation and recovery accuracy. Task 6: Finalize thesis and prepare defense materials.

Deliverables (Besides the final thesis document): - CRDT-based trust propagation protocol - Simulation of partitioned network scenarios - Evaluation report on update consistency and recovery

Evaluation Criteria: - Conflict-free trust update success rate - Performance under varying partition durations - Accuracy of trust reconciliation post-recovery
