    Lightweight detection system of shared spam attacks by Shao-qing LV, Dan FAN, Yu-qing ZHANG

    Published 2015-07-01
    “…Spam is one of the most serious attacks against online social networks (OSN).Recently a new type of spam attack occurs,which named shared spam attack.The shared spam attack can separate the storage and dissemination of spam content,making the existing detection systems no longer effective.To address this problem,an empirical analysis of the process and properties of this new spam attack is performed.A novel lightweight iterative detection algorithm (LIDA) is proposed to detect spam accounts in OSN with these properties.LIDA contains two steps:target filter and content detection.It also noteworthy that LIDA is a lightweight algorithm to infer more spam accounts by exploiting spam accounts’ sharing instead of scanning or analyzing all accounts.Experimental results in RenRen,which has successfully detected 9 568 spam accounts,30 732 spam albums and 2 626 780 spam URL in four round iterations,indicate that LIDA is effective and efficiency in detecting shared spam accounts.…”

    Performance of Polar code in diversity reception system by Pingheng ZHAI, Binsong SHEN, Jinbo LIANG

    Published 2018-02-01
    “…Diversity reception is one of the most effective ways to resist fading over Rayleigh fading channels,in order to improve the performance of Polar codes over Rayleigh fading channels,a diversity reception system based on Polar code was proposed.The information bit selectionsequences of Polar codes in diversity reception were determined,and the upper bound of BER for Polar codes in diversity reception system was derived.The simulation results show that when quadruple diversity reception is used,the encoding gain is greater than 3 dB and has 0.6 dB performance advantage compared to LDPC code.Experiment results show that,when eightfold diversity is used,the encoding gain is greater than 5 dB and has 1.5 dB performance advantage compared to LDPC code,and diversity reception can significantly improve the performance of the system.…”
