摘要： There is described the use of Digital Radio Frequency Memory (DRFM) modules to jam certain communication signals while allowing others to be received on a given frequency band. The DRFM modules exploit the multi-path phenomenon by using transmitted signals to cause full band destructive echoes and/or distortions. A set of receivers used in conjunction with the DRFM modules are aware of the exact multi-path induced by the DRFM modules and are therefore able to mitigate or even benefit from the effects of the destructive multi-path and maintain or improve communications.

摘要： A wireless communication method implemented in a communication system may include receiving a data sequence to be permuted, and obtaining information associated with the data sequence to be permuted, the information containing at least a length of the data sequence and a sampling spacing for permuting the data sequence. The method may also include identifying a first portion of the data sequence having a first number of adjacent data items, and a second portion of the data sequence having a second number of adjacent data items. The method may also include accessing the first number of data items from the first portion at the sampling spacing, and placing the accessed first number of data items into a predetermined number of sub-blocks included within a permuted data sequence to be generated based on the received data sequence. The method may further include inserting each of the second number of data items into an end position of one of the sub-blocks within the permuted data sequence, and outputting the permuted data sequence.

摘要： A simple and efficient method for producing an obfuscated speech signal which may be used to mask a stream of speech, is disclosed. A speech signal representing the speech stream to be masked is obtained. The speech signal is then temporally partitioned into segments, preferably corresponding to phonemes within the speech stream. The segments are then stored in a memory, and some or all of the segments are subsequently selected, retrieved, and assembled into an obfuscated speech signal representing an unintelligible speech stream that, when combined with the speech signal or reproduced and combined with the speech stream, provides a masking effect. While the presently preferred embodiment finds application most readily in an open plan office, embodiments suitable for use in restaurants, classrooms, and in telecommunications systems are also disclosed.

摘要： NADO is a process for encrypting and decrypting information in a variety of cryptographic devices. The underlying process is a fast stream-like cipher that can be implemented efficiently in analog or digital hardware or in software. The NADO process makes use of three novel methods in cryptography: 1) A sequence of permutations which scrambles and spreads out the encrypted information; (2) A state generator built with a non-autonomous dynamical system to generate an unpredictable sequence of states; (3) One or more perturbators which perturb both the non-autonomous dynamical system and the sequence of permutations in a non-periodic way.

摘要： The invention comprises a back-masking effect generator which produces, almost in real time, the simulated sound of an input audio signal being reproduced in reverse. The device digitally records the sound in packets of short duration with alternating packets being written to first and second static random access memory devices, respectively. After an initial state in which the first memory device is filled with the digitized input audio signal, the generator then continuously alternates between two other states. In one state, the second memory device is filled while the first memory device is simultaneously emptied to a digital-to-analog converter in the reverse order from which it was filled. In the other state, the first static random access memory is filled while the second memory device is simultaneously emptied to the digital-to-analog converter.

摘要： A scrambling system for an audio frequency signal in which an audio signal is divided into blocks, each block being formed of a plurality of frames, the plurality of frames are rearranged on a timebase in a predetermined order at every block so as to be encoded and the encoded signal is re-arranged on the timebase in an original order so as to be decoded, in which there are provided a first signal processing circuit for inserting a redundant portion into a portion between adjoining frames and timebase-compressing the frames in response to the redundant portions upon encoding, a control signal generating circuit for inserting a control signal other than an audio information into the redundant portions, a control signal detecting circuit for detecting the control signal upon decoding and a second signal processing circuit for removing the redundant portions in synchronism with the detected control signal and timebase-expanding the frames in response to the redundant portions. Therefore, even when the audio signal is transmitted through a system in a transmission path having a timebase fluctuation such as a transmission path of a VTR (video tape recorder) and the like the frequency band region of which is restricted, the signal waveform is not distorted and a noise is not mixed therein so that the scrambling communication having high quality and high reliability can be presented.
摘要翻译：一种用于音频信号的音频信号的加扰系统，其中音频信号被分成多个块，每个块由多个帧形成，所述多个帧在每个块上以预定顺序在时基上重新排列，以被编码; 编码信号以原始顺序重新排列在时基上以被解码，其中提供了第一信号处理电路，用于将冗余部分插入相邻帧之间的部分，并响应于时基而压缩帧编码后的冗余部分，用于将除音频信息之外的控制信号插入到冗余部分中的控制信号生成电路，用于在解码时检测控制信号的控制信号检测电路和用于去除冗余部分中的冗余部分的第二信号处理电路与检测到的控制信号同步并响应于冗余部分对时基进行扩展。因此，即使音频信号通过具有时频波动的传输路径的系统发送，例如VTR（录像机）的传输路径等，其频带区域被限制，信号波形也不会失真并且不混合噪声，从而可以呈现具有高质量和高可靠性的扰频通信。
