Topology Generation of UAV Covert Communication Networks: a Graph Diffusion Approach with Incentive Mechanism

With the growing demand for Uncrewed Aerial Vehicle UAV networks in sensitive applications, such as urban monitoring, emergency response, and secure sensing, ensuring reliable connectivity and covert communication has become increasingly vital. However, dynamic mobility and exposure risks pose...

A Bayesian Incentive Mechanism for Poison-Resilient Federated Learning

Federated learning FL enables collaborative model training across decentralized clients while preserving data privacy. However, its open-participation nature exposes it to data-poisoning attacks, in which malicious actors submit corrupted model updates to degrade the global model. Existing defens...

No incentive mechanism for allowed senders to call finalizeWithdrawal on behalf of withdrawers.

Lines of code Vulnerability details Impact Since finalizeWithdrawal is a permissioned function, if there are no mechanism in place for allowed senders to trigger it, withdrawers would not able to receive their funds in a timely fashion. Proof of Concept The withdrawal functions such...
