Multi-authority attribute-based encryption access control model for cloud storage by Zhi-tao GUAN, Ting-ting YANG, Ru-zhi XU, Zhu-xiao WANG

“…The existing attribute-based encryption access control studies are mostly based on single authority,and this scheme is apt to be under attack to cause exposure of secret keys.Thus,a multi-authority access control model PRM-CSAC is proposed.Based on CP-ABE method,a multi-authority attribute-based encryption scheme is designed to improve security level.Minimized attribute grouping algorithm is designed to distribute keys to users according to needs,which can reduce unnecessary attribute key distribution and decrease the amount of re-encryption attributes.The read and write attribute are added to strengthen the control of owners.The analysis shows that the proposed scheme can meet the security requirement of access control in cloud,and it also has less response time and system cost.…”

Information extraction from massive Web pages based on node property and text content by Hai-yan WANG, Pan CAO

“…To address the problem of extracting valuable information from massive Web pages in big data environments,a novel information extraction method based on node property and text content for massive Web pages was put forward.Web pages were converted into a document object model (DOM) tree,and a pruning and fusion algorithm was introduced to simplify the DOM tree.For each node in the DOM tree,both density property and vision property was defined and Web pages were pretreated based on these property values.A MapReduce framework was employed to realize parallel information extraction from massive Web pages.Simulation and experimental results demonstrate that the proposed extraction method can not only achieve better performance but also have higher scalability compared with other methods.…”

Multidimensional detection and dynamic defense method for link flooding attack by Yang WANG, Guangming TANG, Cheng LEI, Dong HAN

“…Aiming at the shortcomings of the existing link flooding attack defense methods,a multi-dimensional index detection algorithm is proposed,which performs multi-dimensional detection on the abnormal forwarding links through the five-dimensional elements of connection length,low-speed ratio of data packets,uniformity of data packet distance,average low-speed ratio of data packets,and change rate of low-speed ratio of data packets,thus effectively solving the problem of high false alarm rate of the existing detection methods.Furthermore,a controller switch dynamic deployment method based on coloring theory is proposed,which solves the problem of difficult to be actually deployed in the actual environment with limited switch variant types existing in the existing defense mitigation mechanisms.Experimental analysis show the feasibility of the proposed method.…”

Person re-identification using mid-level features with vertical global appearance constraint by Yadong WANG, Rong ZHANG, Huihui JIANG, Lijun GUO

“…Mid-level features with the semantic information can provide stronger discrimination in the person re-identification than low-level features.But like the low-level features,the mid-level features also use local feature matching methods and easily leads mismatch problem when different pedestrians have similar appearance features in some local areas.Considering the same pedestrians are more similar than different pedestrians in the vertical direction since pedestrians are almost always in a standing position,global vertical appearance constraints was introduced.Furtherly,a method for person re-identification was proposed which fuses the low-level densely patch-matching and the mid-level features with the global vertical appearance constraints.Experimental results show that the proposed algorithm can achieve a higher hit rate than the existing methods on the most challenging public VIPeR database and CUHK01 database.…”

Container intrusion detection method based on host system call frequency by Yimu JI, Weidong YANG, Kui LI, Shangdong LIU, Qiang LIU, Sisi SHAO, Shuai YOU, Naijiao HUANG

“…Container technology has become a widely used virtualization technology in cloud platform due to its lightweight virtualization characteristics.However, it shares the kernel with the host, so it has poor security and isolation, and is vulnerable to flood, denial of service, and escape attacks.In order to effectively detect whether the container is attacked or not, an intrusion detection method based on host system call frequency was proposed.This method took advantage of the different frequency of system call between different attack behaviors, collected the system call generated when the container was running, extracted the system call features by combining the sliding window and TF-IDF algorithm, and classified by comparing the feature similarity.The experimental results show that the detection rate of this method can reach 97%, and the false alarm rate is less than 4%.…”

Communication between nodes in backscatter-assisted wireless powered communication network by Jie TAO, Haijiang GE, Minyuan WU, Qike SHAO, Kaikai CHI

“…At present, there is almost no design on information transmission between the nodes in wireless powered communication network.The high-throughput information transmission between the nodes in backscatter assisted wireless powered communication network was studied.A scheme was proposed which consisted of backscattering/energy transmission phase and active communication phase.The maximum throughput was modeled as a convex optimization problem.Then, based on the relationship between the total backscatter communication duration and the threshold of node energy capture duration, the problem was decomposed into several sub problems that only need to optimize two backscatter durations.An efficient two-level golden section search algorithm was designed to solve the sub problems, and the optimal solution of the original problem was obtained from the optimal solutions of the sub problems.Simulation results show that, compared with pure active communication scheme and pure backscatter communication scheme, the proposed scheme can effectively improve the throughput.…”

Service priority-aware network traffic scheduling mechanism by Huahui LV, Zhida LIN, Hongcong HUANG

“…In view of the problem that network congestion which caused by the uneven distribution in large traffic data,a priority-aware dynamic network traffic scheduling mechanism was proposed.By using the token bucket algorithm,different buckets of different rates were assigned to different services according to the service priorities.The priorities of the service and the remaining buffer space of the user nodes was taken into account to deal with different services.At the same time,the traffic arrival factor,service factor and node cache were regarded as target to define a network traffic scheduling mechanism performance indicator:packet loss rate.The numerical results show that the proposed mechanism can rationally divide the service priorities in the network,effectively utilize the network resources,prevent the network congestion,enhance the network performance,and provide the users with more stable and reliable network service.…”
