Multi-objective Optimization Design of an Aviation Split Path Transmission System by Zhao Ning, Fu Chenxi, Zhao Yongzhi, Fu Bibo

“…The promoting the safety performance and lightweight are considered as the objectives,a multi-objective optimization design of an aviation split path transmission system is conducted.To measure the safety performance of the system,gear contact and bending fatigue strength are computed.Afterwards,a multi-objective optimization model that includes maximum safety factors and minimum mass is developed,with the system parameters selected as design variables.Considering the system requirements for load sharing,a dynamics model of the split path transmission system is established so that the load sharing characteristics can be quantifiably measured and restricted.Non-dominated Sorting Genetic Algorithm II（NSGA-II）is adopted to solve the model.The results show that the method promoted can effectively improve the safety performance and reduce the weight at the same time.…”

Research on intrusion detection for maritime meteorological sensor network based on balancing generative adversarial network by Xin SUN, Guifu ZHANG, Hongyan XING, Wang Zenghui

“…Aiming at the problem that the resources of maritime mobile terminals were limited and the network traffic was imbalanced in the MMSN (maritime meteorological sensor network) environment, which made it difficult to detect network intrusion accurately, a mobile edge computing based physical architecture of MMSN was proposed, and an intrusion detection model based on balancing generative adversarial network was proposed.First, an advanced balancing generative adversarial network was adopted to augment the imbalanced data.Then, a lightweight network based on group convolution was applied to intrusion data classification.Finally, compared with conventional data augmentation models, the computer simulation proves that the proposed model has a higher ability to recognize various attacks, especially minority class attacks on MMSN.…”

Privacy protection key distribution protocol for edge computing by Jian SHEN, Tianqi ZHOU, Chen WANG, Huijie YANG

“…Aiming at the privacy protection problem in the multi-application scenarios of edge computing, two policy-based key distribution protocols were proposed.The proposed protocols are based on the concept of constrained pseudo-random functions to achieve efficient and flexible policy selection.Specifically, based on the GGM pseudo-random number generator, the key distribution protocol with a prefix-predicate is constructed, which can effectively support lightweight and efficient key distribution.Moreover, based on the multilinear pairing, the key distribution protocol with a bit fixing predicate is constructed.This protocol can support flexible and fine-grained strategy selection and is suitable for dynamic and flexible multi-device scenarios in heterogeneous networks.Finally, the security proof of the proposed protocols is presented.…”

Design and detection of hardware Trojan based on satisfiability don't cares by Lingjuan WU, Jiacheng ZHU, Shibo TANG, Jing TAN, Wei HU

“…Hardware Trojans are intended malicious design modifications to integrated circuits, which can be used to launch powerful low-level attacks after being activated.A new security threat of lightweight stealthy hardware Trojans leveraging discrete satisfiability don't care signals was demonstrated.These don't care could not be satisfied under normal operation and thus the circuit design with Trojan is functionally equivalent to the Trojan-free baseline.The attacker could activate the Trojan through simple yet effective fault injection.Experimental results on a 1024-bit RSA cryptographic core show that the proposed hardware Trojan can escape from logic synthesis optimization, and that the RSA private key can be retrieved by simply over-clocking the design.A defense technique that can effectively detect such stealthy Trojan design was provided.…”

A bidirectional authentication protocol for RFID based on Syn by Shanhua ZHAN, Shaorong HUANG

“…The RFID system is made up of three parts:tags,readers and databases.The information between tags and readers are transmitted through wireless channel,which is easy to be intercepted by attackers.A two-way authentication protocol based on word Synthesis operation was proposed.The two remainder theorem was used to encrypt communication messages by the proposed protocol,the difficulty of cracking was increased; In the process of each round of communication encryption,a random number was added to make the communication messages inconsistent,so that the tracking attacks could not be initiated by attackers.In the communication message encryption,the word synthesis algorithms was adopted at the same time,the total calculation of the system could be effectively reduced.A random checking mechanism was introduced at the database,enabling a synchronous attack and other attacks to be effectively resisted by the system.Security analysis shows that the protocol has high security,and performance analysis shows that the protocol has the standard of lightweight computation.…”
