19455 时分多址(TDMA)信号特定辐射源识别(SEI)的性能主要受限于突发数据的长度。 For Time-Division Multiple Access (TDMA) signals, the performance of Specific Emitter Identification (SEI) is primarily limited by burst duration.
19456 为此，该文提出一种新的射频特征，从载波相位上揭示了相邻时隙的用户是否相同，为相同用户的数据累积提供了依据。 To remedy this shortcoming, a novel radiometric signature is presented, which reveals whether the users of the adjacent time slots are the same from a perspective of carrier phase, thereby providing the basis for data accumulation of the same user.
19457 该文首先分析了特征的产生机理，并给出了提取方法； First, the feature mechanism is introduced, as well as the extraction method.
19458 根据特征的统计特性，推导了自适应的判决门限，实现了相邻时隙用户身份的检测； Thereafter, user identity detection of the adjacent slots is implemented with an adaptive threshold, which is derived from the distribution of the signature.
19459 在此基础上，设计了新的SEI处理流程，通过数据累积打破了每个时隙单独识别的传统思维。 Finally, a new SEI processing procedure is designed with data accumulation, which breaks the routine of identifying only one slot at a time.
19460 实验结果表明：该特征对噪声具备良好的鲁棒性，能够实现相邻时隙用户身份的准确检测； Simulation results demonstrate that the proposed signature is resilient against the noise, and can accurately detect the user identity of the adjacent slots.
19461 与传统做法相比，新的处理流程能够有效改善TDMA信号SEI的性能。 Compared with thetraditional processing procedure, the proposed one can effectively improve the SEI performance of TDMAsignals.
19462 异构混合群组签密不仅能够解决不同密码体制下数据传输的机密性和不可伪造性，而且还能对任意长度的数据进行加密。 Heterogeneous hybrid group signcryption can not only solve the confidentiality and unforgeability of data transmission under different cryptosystems, but also encrypt data of any length.
19463 该文首先分析了一种异构密码体制下混合群组签密方案的安全性，指出该方案不满足正确性、机密性和不可伪造性。 Firstly, the security of ahybrid group signcryption scheme under heterogeneous cryptosystem is analyzed, and it is pointed out that thescheme does not satisfy the correctness, confidentiality and unforgeability.
19464 并提出了一种新的高效异构混合群组签密方案。 And a new efficient heterogeneous hybrid group sign cryption scheme is proposed.
