DDoS attack detection method based on conditional entropy and GHSOM in SDN by Junfeng TIAN, Liuling QI

“…Software defined networking (SDN) simplifies the network architecture,while the controller is also faced with a security threat of “single point of failure”.Attackers can send a large number of forged data flows that do not exist in the flow tables of the switches,affecting the normal performance of the network.In order to detect the existence of this kind of attack,the DDoS attack detection method based on conditional entropy and GHSOM in SDN (MBCE＆amp;G) was presented.Firstly,according to the phased features of DDoS,the damaged switch in the network was located to find the suspect attack flows.Then,according to the diversity characteristics of the suspected attack flow,the quaternion feature vector was extracted in the form of conditional entropy,as the input features of the neural network for more accurate analysis.Finally,the experimental environment was built to complete the verification.The experimental results show that MBCE＆amp;G detection method can effectively detect DDoS attacks in SDN network.…”

Application of invariant moment method for HAPS ISAR imaging with micro parts by Zhao-qun QI, Xiao-jun JING, Si-qing YOU, Hai-bin SUN

“…To resolve the micromotion in the HAPS(high altitude platform station) ISAR system,the invariant moment method for ISAR imaging with micro parts was proposed.Firstly,invariant moment tool was applied to classify the echoes of different sub-aperture,and then the sub-aperture echoes reducing the quality of image was separated.Finally the remaining echoes were used to do sub-aperture splicing imaging.From the simulation results,the algorithm is proved to be simple and can improve the quality of ISAR image obviously.…”

Membership inference attack and defense method in federated learning based on GAN by Jiale ZHANG, Chengcheng ZHU, Xiaobing SUN, Bing CHEN

“…Aiming at the problem that the federated learning system was extremely vulnerable to membership inference attacks initiated by malicious parties in the prediction stage, and the existing defense methods were difficult to achieve a balance between privacy protection and model loss.Membership inference attacks and their defense methods were explored in the context of federated learning.Firstly, two membership inference attack methods called class-level attack and user-level attack based on generative adversarial network (GAN) were proposed, where the former was aimed at leaking the training data privacy of all participants, while the latter could specify a specific participant.In addition, a membership inference defense method in federated learning based on adversarial sample (DefMIA) was further proposed, which could effectively defend against membership inference attacks by designing adversarial sample noise addition methods for global model parameters while ensuring the accuracy of federated learning.The experimental results show that class-level and user-level membership inference attack can achieve over 90% attack accuracy in federated learning, while after using the DefMIA method, their attack accuracy is significantly reduced, approaching random guessing (50%).…”
