    Node selection method in federated learning based on deep reinforcement learning by Wenchen HE, Shaoyong GUO, Xuesong QIU, Liandong CHEN, Suxiang ZHANG

    Published 2021-06-01
    “…To cope with the impact of different device computing capabilities and non-independent uniformly distributed data on federated learning performance, and to efficiently schedule terminal devices to complete model aggregation, a method of node selection based on deep reinforcement learning was proposed.It considered training quality and efficiency of heterogeneous terminal devices, and filtrate malicious nodes to guarantee higher model accuracy and shorter training delay of federated learning.Firstly, according to characteristics of model distributed training in federated learning, a node selection system model based on deep reinforcement learning was constructed.Secondly, considering such factors as device training delay, model transmission delay and accuracy, an optimization model of accuracy for node selection was proposed.Finally, the problem model was constructed as a Markov decision process and a node selection algorithm based on distributed proximal strategy optimization was designed to obtain a reasonable set of devices before each training iteration to complete model aggregation.Simulation results demonstrate that the proposed method significantly improves the accuracy and training speed of federated learning, and its convergence and robustness are also well.…”

    Verifiably secure fast group authentication protocol with anonymous traceability for Internet of vehicles by Haibo ZHANG, Hongwu HUANG, Kaijian LIU, Xiaofan HE

    Published 2021-06-01
    “…Identity authentication is the first line of defense for vehicles to access IoV (Internet of vehicles).However, the existing schemes cannot meet the requirements of efficient authentication of IoV well, nor can they realize fast anonymous traceability.In view of this, a bidirectional anonymous traceability group authentication protocol was proposed in IoV.In this protocol, a number of RSU (road side unit) were grouped quickly and dynamically.And the vehicles entering the RSU group were authenticated with the one-way trap gating property and semi-group property of Chebyshev chaotic map.When the vehicle switched between the RSU within a group, the reverse hash chain was used for fast handover authentication.In addition, the RSU within a group can trace anonymously and revoke the identity of malicious vehicles quickly by using blockchain, and can also freely change the ID of users who reveal their real identity.At the same time, the semantic security of the proposed protocol is proved by using the random predictor model.Finally, simulation results show the proposed scheme has good security and effectiveness.…”
