DAGUARD: distributed backdoor attack defense scheme under federated learning by Shengxing YU, Zekai CHEN, Zhong CHEN, Ximeng LIU

“…In order to solve the problems of distributed backdoor attack under federated learning, a distributed backdoor attack defense scheme (DAGUARD) under federated learning was proposed based on the assumption that the server selected no more than half of malicious clients for global aggregation.The partial update strategy of the triple gradient optimization algorithm (TernGrad) was designed to solve the backdoor attack and inference attack, an adaptive density clustering defense scheme was designed to solve the backdoor attacks with relatively large angle deflection, the adaptive clipping scheme was designed to limit the enhancement backdoor attack that amplify the gradients and the adaptive noise-enhancing scheme was designed to weaken distributed backdoor attacks.The experimental results show that in the federated learning scenario, the proposed scheme has better defense performance and defense stability than existing defense strategies.…”

Access mechanism of TMP under mobile network by WU Zhen-qiang, ZHOU Yan-wei, QIAO Zi-rui

“…The publication of TCG MTM standard ensured the safety of mobile terminal and its promotion results in the changes of communication on mobile terminals.An access mechanism to trusted mobile platform（mobile terminals with MTM chips,TMP） was proposed on mobile Internet.This mechanism defined an extended service set as a service field,introduced TMP and Internet ISP of strategy decider management field,and defined two visit mode of TMP on mobile Internet,self field service and cross field visit.The progress of each mode was described in details.Cross field visit mode was defined as roaming service and resource request.The trusted evaluation system of TMP access mechanism was specifically described.Universal combinational safe mode was used to analyze the safety of the two TMP access.The analysis shows that this mechanism brings about trusted TMP access on mobile Internet and is safe,practical and high efficient.…”

Adaptive double auction mechanism for cloud resource allocation by Ding DING, Si-wei LUO, Li-hua AI

“…By integrating the auction mechanism in economic field into cloud,an adaptive double auction mechanism(ADAM) was proposed to allocate resources in cloud computing.Compared to traditional double auction mechanisms,ADAM traded cloud resource sellers and cloud resource buyers at their expected price and quantity,guaranteed the profits of all participants.Moreover,ADAM applied different auction rules in different cases to satisfy as more participants as possible.As a new mechanism for cloud resource allocation,ADAM was proved to be strategy-proof,weakly budget-balanced and individual rational even under the conditions that the price and quantity of participants were private information.Simulation results also confirm that ADAM outperforms the traditional one on both cloud user satisfaction degree and cloud resource utilization rate and is also economically efficient,especially as more users are involved in the auction market.…”
