47106 该方法首先对 MISO 通信系统的 STBC-OFDM 信号建模; Firstly, the model of received STBC-OFDM signals in MISO systems was giv-en.
47107 然后利用 STBC-OFDM 信号编码矩阵的相关性,构造不同时延向量下 STBC-OFDM 接收信号 OFDM 块的经验函数作为特征函数; Secondly, with the correlation of the coding matrix of STBC-OFDM signals, and the discrimination features functionprovided by the empirical cumulative distribution (CDFs) of the received OFDM blocks was constructed.
47108 最后通过改进 K-S 检测方法检验经验分布函数之间的距离盲识别 STBC-OFDM 信号。 Finally, the dis-tance between CDFs was tested by the two-sample K-S test, which could blindly classify the STBC-OFDM signals.
47109 该方法不需要噪声信息、调制信息和信道系数,适合非合作通信场合。 Theproposed algorithm didn’t need the estimation of channel, noise statistics and modulation type, and consequently, was wellsuited for non-cooperative communication context.
47110 理论分析和实验验证了该方法的可行性。 Theoretical analysis and experimental verify its validity.
47111 Liu 等在 2010 年提出了一种在标准模型下可证明安全的无证书签密算法(简称 LHZ 算法),但后续的研究成果显示 LHZ 算法实际上是不安全的。 In 2010, Liu, et al. proposed a certificateless signcryption scheme in the standard model, but many analysesrevealed that Liu’s scheme was insecure in fact.
47112 为了克服 LHZ 算法的不足,首先改进 LHZ 签密算法, To overcome the disadvantages, the scheme was improved and a certifi-cateless generalized signcryption scheme was constructed.
47113 然后以此为基本的签密算法提出一种新的无证书广义签密算法。 In addition, a formal security model for the proposed schemeagainst the malicious-but-passive KGC attacks was introduced.
47114 同时给出了抵抗有预谋的 KGC 被动攻击(malicious-but-passive KGC attack)的无证书广义签密算法的安全性模型,并在标准模型下证明了该算法在判定性双线性Diffie-Hellman 困难问题和计算性 Diffie-Hellman 困难问题假设下是安全的。 Furthermore, the proposed scheme was proven to be se-cure under the decisional bilinear Diffie-Hellman and the computational Diffie-Hellman intractability assumptions in thestandard model.
47115 此外,数值实验结果表明所提方案是有效的。 Numerical results illustrate that the proposed algorithm is efficient.
