    • A system for fast data encryption/decryption is provided. The system includes a transmitter system having a transmitter direct digital synthesizer (DDS). The DDS includes at least three transmitter pseudo-noise (PN) component code generators PNx, PNy, PNz, where each transmitter PN component code generator is adapted to generate relatively prime transmitter PN component codes when compared with each of the other transmitter PN component code generators. The transmitter also includes a first processor coupled to the transmitter DDS, where the first processor is adapted to determine a time slot number (TSN) relative to at least two of the relatively prime transmitter PN component codes. Also included in the transmitter is an encryptor for encrypting clear data in accordance with the TSN. The system includes a receiver system having a second processor adapted to determine the TSN; and a decryptor coupled to the second processor. The decryptor is adapted to decrypting the encrypted clear data in accordance with the TSN.
    • 提供了一种用于快速数据加密/解密的系统。 该系统包括具有发射机直接数字合成器(DDS)的发射机系统。 DDS包括至少三个发射机伪噪声(PN)分量码发生器PN×××××××××××××××,其中每个发射机PN 当与其他发射机PN分量码发生器中的每一个比较时,分量码发生器适于产生相对主要的发射机PN分量码。 发射机还包括耦合到发射机DDS的第一处理器,其中第一处理器适于相对于相对主要的发射机PN分量码中的至少两个来确定时隙号(TSN)。 还包括在发射机中的是用于根据TSN加密清除数据的加密器。 该系统包括具有适于确定TSN的第二处理器的接收机系统; 以及耦合到所述第二处理器的解密器。 解密器适于根据TSN解密加密的清除数据。
