[Retracted] An Artificial Intelligence Mechanism for the Prediction of Signal Strength in Drones to IoT Devices in Smart Cities

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Drones, the Internet of Things (IoT), and Artificial Intelligence (AI) could be used to create extraordinary responses to today’s difficulties in smart city challenges. A drone, which would be effectively a data‐gathering device, could approach regions that become complicated, dangerous, or even impossible to achieve for individuals.

Attribute‐based ring signcryption scheme

Security and Communication Networks, 2012
ABSTRACTIn this paper, we present attribute‐based ring signcryption scheme, which realizes the concept of ring signcryption in the attribute‐based encryption frame firstly. In our system, it allows a user to signcrypt a message by a set of attributes that are chosen without revealing its identity. In additional, we propose the security models and prove

DRFL: A Dual‐Encryption and Reputation Evaluation Defence Against Malicious Attacks on Federated Learning

IET Communications, Volume 20, Issue 1, January/December 2026.
Federated learning (FL) enables collaborative model training without collecting user data but faces security risks such as privacy breaches, poisoning, and free‐rider attacks. To address these challenges, we propose DRFL, a defense mechanism integrating dual encryption, reputation evaluation and blockchain to enhance security and transparency ...
