摘要：

With the same transmission rate and Bit Error Rate (BER) as the traditional Direct Sequence Spread Spectrum (DSSS) system, the stronger anti-interception performance can be obtained by Orbital Angular Momentum (OAM). In other words, the contradiction between the transmission rate and the security can be solved by the double-channel OAM Spread Spectrum (SS) system. In this paper, the performance of the low probability of intercept and the low probability of detection are evaluated by Computational Complexity (CC) and Channel Exposure Time (CET), respectively. In addition, the case of transmitting the generator polynomial coefficients by OAM, as well as the cases with encryption algorithms, are proposed and verified. As a result, these proposed schemes greatly increase the CC and reduce the CET, which means that the great improvement of the anti-interception performance can be achieved.
