    Using rule association to generate data collection policies by Pei CHEN, Fenghua LI, Zifu LI, Yunchuan GUO, Lin CHENG

    Published 2021-10-01
    “…Collecting security-related data of devices effectively is the foundation of analyzing network threats accurately.Existing data collection methods (full data collection, sampling based data collection and adaptive data collection) do not consider the validity of the collected data and their correlation, which will consume too much collection resources, resulting in low collection yield.To address this problem, considering the factors (relationship between node attributes, network topology relationship, threat status, node resource and node similarity) that impact collection costs and benefits, a rule association method to generate collection policies was designed.In the method, two types of association rules (inter-node association rules and inter-event association rules) were adopted to generate candidate data collection items and reduced the scope of data collection.Then, a multi-objective program was designed to maximize collection benefits and minimize collection costs.Further, a genetic algorithm was designed to solve this program.Proposed method was compared with existing data collection methods.The experimental results show that the number of the collected data records of proposed method is 1 000~3 000 less than that of others per 12 hours, and the validity of the collected data of proposed method is about 4%~10% higher than others, which proves the effectiveness of the proposed method.…”

    Crowd-based collaboration caching mechanism in smart identifier network by Haifeng LI, Wei QUAN, Nan CHENG, Hongke ZHANG, Xuemin SHEN

    Published 2018-12-01
    “…Smart identifier network (SINET) is an innovative network architecture.Through dynamic collaboration of service resource,function groups and physical components,the network scalability,resource utilization and service quality were effectively improved by SINET,and an effective solution for the development of industrial Internet of things(IoT) could be provided.To promote content delivery in resource-constrained IoT,caching function was introduced in network components by SINET,and the bandwidth waste caused by traffic redundancy in resource-constrained node could be reduced.Therefore,how to efficiently cache content became an important research topic.Based on SINET architecture,a crowd-based collaboration cache (C2Cache) mechanism was proposed in this scheme.According to the actual network topology,the caching function group was dynamically created and optimized by C2Cache,and a function group as crowd minimum unit to execute the maximum benefit cache (MBC) algorithm was defined to maximize the caching space efficiency.With the self-developed emulation system,named EmuStack,the performance of C2Cache was evaluated.The experimental results show that,comparing with LCE,Random,Prob Cache,LCD and Greedy caching mechanisms,the cache hit rate can be improved effectively,then the average access time can be reduced significantly by C2Cache.In the simulated network scenario,the performance increases 15% to 30%.…”

    An Interlayer Link Prediction Method Based on Edge-Weighted Embedding by Hefei Hu, Sirui Zhang, Yanan Wang

    Published 2023-01-01
    “…However, these studies often directly model links within the pre-embedding layer as equal weights, fail to effectively distinguish the strength of edge relationships, and do not fully utilize network topology information. In this paper, we propose an interlayer link prediction model based on weighted embedding of connected edges within the network layer, which models the links within the network layer as weighted graphs to better represent the network and then uses appropriate embedding methods to represent the network in a low-dimensional space. …”
