摘要： In order to prevent, without significantly reducing the power of a transmission path, a signal unnecessary for a branch station from being intercepted at the branch station, a node apparatus comprises: a first optical unit that outputs a first optical signal received from a first terminal station and addressed to a second terminal station and also outputs a second optical signal received from the first terminal station and addressed to a third terminal station; and a second optical unit that receives the first and second optical signals outputted from the first optical unit, optically removes a portion of the spectrum of the first optical signal, thereby generating a fourth optical signal, and passes the second optical signal as it is, thereby transmitting the second optical signal together with the fourth optical signal to the third terminal station.

摘要： In an example, there is disclosed a system and method for a two-device scrambled display. A first device displays content in a scrambled form. A second device acts as an interpreter, including an input driver for receiving a scrambled input; an output driver for displaying an organically perceptible output; and one or more logic elements comprising a unscrambling engine operable for: receiving an input on the input driver; detecting that at least a portion of the input is scrambled; unscrambling the scrambled portion of the input; and outputting an unscrambled analog of the scrambled input via the output driver.

摘要： A first network device may discover one or more values of one or more parameters corresponding to a plurality of links and/or devices of the network. The first network device may compare the discovered one or more values of the one or more parameters to an expected one or more values of the one or more parameters. The first network device may determine whether to transmit data onto a network path between the first device and one of the plurality of devices based on a result of the comparison, wherein at least one of the plurality of links and/or devices are not part of the network path. The first network device may be operable to utilize the discovered parameter values to generate a security key which may be utilized to encrypt and/or scramble content prior to transmitting the content onto the network.

摘要： A technique for tamper protection of incoming data signal to an electronic device is disclosed. An intentional interference signal is generated and modulated onto the incoming data signal as one composite input signal, to prevent unauthorized acquisition of valid data from the incoming data signal. The magnitude of the interference signal is adjusted to correspond to the magnitude of the incoming data signal, thereby preventing an attacker from properly differentiating the two different signals and/or decoding the valid data from the composite input signal. Once the composite input signal is safely received within the device, the interference signal can be filtered out in either analog mode or digital mode.

摘要： A secure communication system utilizes multiple “decoy” data signals to hide one or more true data signals. The true data signal(s) are encrypted, and received at a scrambling unit according to an original set of channel assignments. The channel assignments are optically switched with multiple decoy data signals to form a multi-channel “scrambled” output signal that is thereafter transmitted across a communication system. The greater the number of decoy signals, the greater the security provided to the open-air system. Further security may be provided by encrypting the decoy signals prior to scrambling and/or by utilizing a spatially diverse set of transmitters and receivers. Without the knowledge of the channel assignment(s) for the true signal(s), an eavesdropper may be able to intercept (and, with time, perhaps descramble) the open-air transmitted signals, will not be able to distinguish the true data from the decoys without also knowing the channel assignment(s).
摘要翻译：安全通信系统利用多个“诱饵”数据信号来隐藏一个或多个真实数据信号。真实数据信号被加密，并且根据原始的信道分配集合在加扰单元处被接收。信道分配通过多个诱饵数据信号进行光学切换，以形成随后通过通信系统传输的多信道“加扰”输出信号。诱饵信号的数量越多，对露天系统的安全性就越大。可以通过在加扰之前加密诱饵信号和/或通过利用空间不同的一组发射器和接收器来提供进一步的安全性。窃听者无需知道真实信号的信道分配，就可以拦截（并且随着时间的推移，或许解扰）露天传输的信号，将无法区分真实数据从诱饵而不知道频道分配。

摘要： The present invention discloses a visible light signal transmitting and receiving processing method, a transmitting terminal, a receiving terminal, and a system. The method includes: performing, by a transmitting terminal, an operation between data to be sent and a pseudocode signal of the transmitting terminal to output a scrambled code signal; combining, by the transmitting terminal, the scrambled code signal with a light guide signal to obtain a signal to be sent, where the light guide signal includes identity information of the transmitting terminal; and transmitting, by the transmitting terminal, the signal to be sent in light form. The present invention solves a problem that an encryption method for visible light communication in a related art is applicable to only one transmitting terminal, and thereby multiple transmitting terminals can be supported.
