EBS-based efficient and secure group key management in wireless sensor networks by WANG Wei1, ZHAO Wen-hong2, LI Feng-hua3.4, MA Jian-feng3

“…To achieve the secure group communication in wireless sensor networks（WSN）, a EBS-based group key management scheme was presented.First, the network topology was simplified by combining the chain-clusters and the star-clusters.Next, to prevent the adversary uncover all the administrative keys by a few colluding sensors, the number of sensors needed to capture WSN was increased.Then, the sensors of key combinations distribution were sorted through a coloring algorithm.Based on all these operations, the presented scheme distributed the administrative keys based on the hamming distance and EBS.Furthermore, the approaches handling the join event and leave event were described.Two experiments were performed to study the potential for collusions and the influence of size of compromised nodes on the effectiveness against collusions.Simulation results demonstrate that the presented scheme boosts the WSN’ resilience to attacks.The performance evaluation on join event and leave event shows that the number of key-updating messages and storage of sensors in the proposed scheme are fewer than those of SHELL.…”

“…Aiming at the problems of data leakage of perceptual image and computational inefficiency of privacy-preserving classification framework in edge-side computing environment, a lightweight and privacy-preserving classification framework (PPCF) was proposed to supports encryption feature extraction and classification, and achieve the goal of data transmission and computing security under the collaborative classification process of edge nodes.Firstly, a series of secure computing protocols were designed based on additive secret sharing.Furthermore, two non-collusive edge servers were used to perform secure convolution, secure batch normalization, secure activation, secure pooling and other deep neural network computing layers to realize PPCF.Theoretical and security analysis indicate that PPCF has excellent accuracy and proved to be security.Actual performance evaluation show that PPCF can achieve the same classification accuracy as plaintext environment.At the same time, compared with homomorphic encryption and multi-round iterative calculation schemes, PPCF has obvious advantages in terms of computational cost and communication overhead.…”

Research on scheduled WLAN MAC protocol with failure retries on RoF-DAS architecture by Zheng GUAN, Lei XIONG, Yao JIA, Min HE, Zhijun YANG

“…Aim to reduce control frames consumption and improve the delay performance,a scheduled gated-service polling access (SGPA) mechanism was proposed,in which the total data packets in the buffer at the polling instant were aggregated into a data set,that was transmitted and acknowledged uniformly.Then,an inner-arrival gated-service polling (IAGP) model was proposed to analyze the quantitative relationship between failure retry mechanism and network access performance of the wireless local area network (WLAN) in RoF-DAS.The failure retry mechanism were modeled as the arrival and service process of inner customers in IAGP.Using the Markov chain and generating function method,the closed-form expressions for the quantitative relationship between delay performance and retrial parameters,such as retry times,and the probability of retransmission,were achieved.The simulation results show that the proposed SGPA can achieve a lower delay than IEEE 802.11,and the theoretical performance evaluation calculated by IAGP are identical with the simulation results,which provides an effective evaluation mechanism for the access performance in RoF-DAS WLAN,with inperfect channel and failure retry mechanism.…”
