    Block ciphers identification scheme based on the distribution character of randomness test values of ciphertext by Yang WU, Tao WANG, Meng XING, Jin-dong LI

    Published 2015-04-01
    “…By researching deficiency of current encryption algorithms identification schemes,a block ciphers identification scheme is proposed based on the distribution character of randomness test values for ciphertext.Firstly,the numbers of randomness test values for AES,Camellia,DES,3DES,SMS4 are respectively calculated based on the frequency test,frequency test in block,run test and originally clustered by the k-means algorithm.Secondly,in order to identify the block ciphers in each clustering,the dimensions of eigenvectors to the frequency test,frequency test in block,run test are calculated on the principle of reducing the comparability between eigenvectors.Eventually,the experimental results of AES,Camellia,DES,3DES,SMS4 demonstrate that the proposed scheme effectively identified the above representative block ciphers,and the correlative research can promote the further encryption algorithms identification research.…”

    CFO-CR: Carrier Frequency Offset Methodology for High-Rate Common Randomness Generation by Prashanth Kumar Herooru Sheshagiri, Martin Reisslein, Juan A. Cabrera, Frank H. P. Fitzek

    Published 2025-01-01
    “…Our proposed CFO-CR methodology can generate 2048 bits of CR at a comparatively low reconciliation cost of 72 bytes while only making 256 channel observations and passing all common randomness tests. For generating 2048 bits of CR, other state-of-the-art approaches either require more channel observations (<inline-formula> <tex-math notation="LaTeX">$\ge 2048$ </tex-math></inline-formula>) or incur a higher reconciliation cost (<inline-formula> <tex-math notation="LaTeX">$\ge 450$ </tex-math></inline-formula> bytes).…”

    Parameter selection of autocorrelation test for block ciphers by FAN Li-min1, FENG Deng-guo1, ZHOU Yong-bin1

    Published 2009-01-01
    “…Autocorrelation test was a statistical test to evaluate the correlation between one sequence and the corresponding non-cyclic left-shifted d bits sequence.It was impractical to adopt all the values of d since its range was often very wide.Three relations between parameters of randomness test were defined firstly.Then the relationships among the subclass D={1,2,m/4,m/2,3m/4,m,2m}of autocorrelation test for block cipher were studied by statistical experiments,where m was block length.The experiments show that the prefer choice of parameter d is m when doing autocorrelation test for block cipher.The method is also available for parameter selection of other randomness test for other types of cryptosystem.…”

    ANALYSIS OF LABORATORY TESTS FOR SEVERAL VIRAL SWINE DISEASES IN RUSSIA IN 2011–2017 by A. A. Shevtsov, O. N. Petrova, S. G. Remyga, A. S. Pershin, K. N. Gruzdev, A. S.  Igolkin

    Published 2018-05-01
    “…But it is not always possible to read the test results unambiguously and that requires the improvement of diagnostic practices supported by established rules of sampling, laboratory tests and obtained result submission. It means random tests shall be representative for tested populations, correlate with the prevalence of concerned infection and meet the required certainty. …”

    Boolean-chaos-based physical random number generator by Qiqi ZHANG, Jianguo ZHANG, Pu LI, Yanqiang GUO, Yuncai WANG

    Published 2019-01-01
    “…A novel method for generating physical random numbers using Boolean-chaos as the entropy source was proposed.An autonomous Boolean network (ABN) without self-feedback was constructed by using two-input logic gates,and its dynamic characteristics were analyzed.Based on this,a 15-node ABN circuit was implemented to successfully generate Boolean-chaos with a bandwidth of ~680 MHz and a min-entropy around 1.By implementing the entropy source and the entropy extraction circuit on a single FPGA,the physical random number generation with a real-time rate of 100 Mbit/s was finally achieved.The NIST SP800-22 and DIEHARD randomness test results demonstrate that the obtained random sequences by the method successfully pass all tests.This indicates the random numbers has good random statistical characteristics.…”

    Research on test strategy for randomness based on deep learning by Dongyu CHEN, Hua CHEN, Limin FAN, Yifang FU, Jian WANG

    Published 2023-06-01
    “…In order to achieve better test performance, researches on the randomness test strategies based on deep learning were conducted, including the batch average strategy proposed by EUROCRYPT 2021 and the selection strategy for data unit size.By introducing the randomness statistical test model based on deep learning methods, the statistical distribution and test power expression of two test strategies were theoretically derived, and it was pointed out that: (i) the batch average strategy could amplify the prediction accuracy of the model, but it was prone to an increase in the probability of the second type of error in statistics, instead reducing the statistical test power; (ii) the smaller data units of the deep model generally obtained the more powerful statistical tests.Based on the above understanding, a new bit-level deep learning model was proposed for randomness statistical tests, which gained the advantage of prediction with 80 times fewer parameters and 50% samples, compared with the previous work on linear congruent generator (LCG) algorithm, and achieved significant prediction advantages with 10~20 times fewer parameters by extending the model to apply to 5~7 rounds of Speck, compared with the model proposed by Gohr.…”

    Published 2022-06-01
    “…Based on these data an Artificial Intelligence (AI) machine-learning species identifier has been developed that takes as input locality data and a small number of the morphological parameters. Using a random test set of more than 600 collections from the database, not utilized within the set of collections used to train the identifier, the species identifier was able to identify 77% correctly with its highest probabilistic match, 96% within its three most likely determinations and over 99% of collections within its five most likely determinations.…”
