    Joint amplitude and phase partition based physical layer key generation method by Nannan LI, Yu HAN, Ning GAO, Shi JIN

    Published 2021-05-01
    “…A key generation method based on wireless channel physical layer features is of great significance for improving security of wireless transmission.An orthogonal frequency division multiplexing (OFDM) communication system based on time division duplex (TDD) with multipath fading channels was considered.Utilizing the advantages of OFDM multicarrier and the channel reciprocity and combining the phase and amplitude information of channel frequency response (CFR), two algorithms for physical layer key generation were proposed.Theoretical analysis and experimental simulation show that the proposed algorithm has more consistent and smaller overhead in information negotiation, in addition, the proposed algorithm can increase the key length and enhance randomness, and has a better defense capability against eavesdropping and active attacks of the illegal user.…”

    Graph partition based mapping algorithm on multiprocessors for streaming applications by Qi TANG, Shang-feng WU, Jun-wu SHI, Ji-bo WEI

    Published 2016-06-01
    “…To take advantage of multiprocessor platform,it is a necessity to map tasks of the application properly onto different processors to exploit the concurrency in the application and thus meet the stringent timing requirements.Parallelism graph was proposed to quantify and model the concurrency among tasks of the application.An algorithm was also proposed to construct the parallelism graph based on the self-timed schedule and transform the mapping problem to a graph partitioning problem.The graph partitioning problem as a pure 0-1 integer linear programming model was further formulated and the ILP solver to find the optimal result.A lot of randomly generated synchronous dataflow graphs and a set of practical applications were used to evaluate the performance of the proposed method.The experimental results demonstrate that the proposed method outperforms available algorithms.…”

    Steganalysis for stegotext based on text redundancy by LUO Gang, SUN Xing-ming

    Published 2009-01-01
    “…Targeted at the text steganography with mimic model,a steganalysis method based on source redundancy for stegotexts was proposed.This method processed the text and the words in it as the m-order Markov source and the source symbols respectively,then computed the redundancy of the source.Through analyzing the relationship between the re-dundancy and the size of the text,the existence of hidden information could be determined.With testing of 8 000 ste-gotexts produced by the four main softwares NiceText,Texto,Stego and Sams Big Play Maker,and 2 400 normal texts randomly sampled from innocuous texts downloaded from the Internet,the results show that the false positive rate of our steganalysis method is 0.5% and the false negative rate is 3.9%.Experiments and analyzing results indicate that the steganalysis method can effectively detect stegotexts based on natural language processing with mimic model.…”

    Multipurpose watermarking realizing image copyright notification,copyright protection and content authentication by ZHU Cong-xu

    Published 2009-01-01
    “…A multipurpose image watermarking scheme based on chaotic systems and sub-image lifting wavelet transformation(LWT) was proposed.Firstly, the host image was divided into 8×8 sub-images and each sub-image was performed 2-level LWT.Then, the invisible watermarks for copyright protection and content authentication were respectively embedded into low and intermediate frequency LWT components of some sub-images that were randomly selected by general Arnold map.A new kind of quantization technique was adopted in the embedding process and the extracting process was blind.Secondly, the visible watermarks for copyright notification were embedded into the image spatial domain based on image fusion method, in which the embedding coefficients were generated by the 4D hyperchaotic sequences.Experimental results were presented, showing that the proposed watermarking scheme is effective.…”

    Published 2017-07-01
    “…The maxout units have the problem of not delivering non-max features, resulting in the insufficient of pooling operation over a subspace that is composed of several linear feature mappings,when they are applied in deep convolutional neural networks.The mixed maxout (mixout) units were proposed to deal with this constrain.Firstly,the exponential probability of the feature mappings getting from different linear transformations was computed.Then,the averaging of a subspace of different feature mappings by the exponential probability was computed.Finally,the output was randomly sampled from the max feature and the mean value by the Bernoulli distribution,leading to the better utilizing of model averaging ability of dropout.The simple models and network in network models was built to evaluate the performance of mixout units.The results show that mixout units based models have better performance.…”
