    Uncertain data analysis algorithm based on fast Gaussian transform by Rong-hua CHI, Yuan CHENG, Su-xia ZHU, Shao-bin HUANG, De-yun CHEN

    Published 2017-03-01
    “…The effect of the uncertainties needs to be taken full advantage during uncertain data clustering.An uncertain data clustering algorithm based on fast Gaussian transform was proposed,to solve the problems about the impact on the accuracy of clustering results and the clustering efficiency caused by the uncertainties,during the construction of uncertain data models and the distance measurement,which existed in the current researches.First,the data model according to the characteristic of the uncertainty distribution was constructed,without the premise of assuming the data distribution.And the similarity between uncertain data objects was measured by combining the two important features of uncertain objects,attribute features and the probability density function representing the characteristic of uncertainty distribution.And then the uncertain data clustering algorithm was proposed.Finally,the experiment results on UCI and real datasets indicate the better efficiency and accuracy of proposed algorithm.…”

    Adaptor signature scheme based on ISRSAC digital signature algorithm by Yanshuo ZHANG, Ning LIU, Yuqi YUAN, Yatao YANG

    Published 2023-03-01
    “…The adapter signature scheme can provide good properties of atomic exchange in the block chain, and has been widely used in practice.A new adapter signature scheme was constructed based on a digital signature algorithm for improved security of RSA cryptosystem (ISRSAC).After proving that the proposed scheme satisfied the correctness of the pre-signature, unforgeability, adaptability of the pre-signature, extractability of the evidence and the security of the signature scheme, it was compared with the adapter signature scheme based on the SM2 digital signature algorithm, the Schnorr-based adapter signature scheme and the ECDSA-based adapter signature scheme.And these schemes were analyzed in terms of time overhead and main calculation amount.The analysis results show that the proposed scheme is similar to other schemes in terms of time overhead, but the proposed scheme expands the application scenarios of ISRSAC algorithm in the current environment, and through the combination of ISRSAC algorithm and adapter signature technology, the selection of adapter signature is more flexible and can have a wider range of applications.…”

    Virtual Network Embedding Algorithms for Integrated Space-Terrestrial Network by Jiarui FANG, Tingting ZHANG, Yubo ZHAO, Nan WU, Bei LIANG

    Published 2024-03-01
    “…Within the intricate environment of integrated space-terrestrial network, VNE algorithms face novel challenges due to the high variability in user demands, stringent limitations of heterogeneous resources, expansive spatiotemporal scales, and the dynamic nature of network topologies.In light of this, scholars worldwide have delved deeply into the VNE issues pertaining to these networks.This review firstly summarized the three core challenges faced by VNE in these networks based on their characteristics.It then elucidated the current state of research from two major perspectives: scenario modeling and algorithmic solutions, primarily encompassing Quality of Service (QoS) aware VNE, multi-layer cross-domain heterogeneous network VNE, dynamic VNE, and problem-solving algorithms for VNE.Both theoretical and practical strategies to address the VNE challenges in integrated space-terrestrial networks were analyzed in depth.Finally, it provided a foresight into future research directions, aim to offer valuable insights for subsequent studies.…”
