20080298802 | OPTICAL SIGNAL MEASUREMENT DEVICE - A device connects to a male network connector of a network conduit, and connects to a female network connector of the network conduit. The female network connector is capable of communicating with the male network connector. The device also measures outputs of the male network connector and the female network connector. | 12-04-2008 |
20090148159 | Method and Apparatus for Securing Fiber in an Optical Network - A method and apparatus for securing an optical communication link includes the step of identifying a profile of the link by measuring, at the transmitter, optical back-reflections from optical pulses forwarded to a receiver. The profile is stored at the transmitter. Periodically during operation, such as during key exchange, more optical pulses are forwarded to the receiver, and the back reflections are collected as periodic profiles. The periodic profiles are compared against the stored profiles. Eavesdroppers, such as those who cut the fiber, tap the fiber, or implement a man in the middle attack, may be easily identified because the losses caused by their interference with the fiber will be evident in the periodic profiles. | 06-11-2009 |
20110019997 | System for intercepting signals to be transmitted over a fiber optic network and associated method - A system is provided for intercepting signals transmitted between a target served by a fiber optic network and a subscriber. A network is described having a phone switch at a central office configured to receive signals for transmission to and from a target, such as the target of a criminal investigation. A signal received at the central office is assigned to an analog circuit, and a monitoring device configured to intercept and monitor the signal is installed along the analog circuit at a location that allows the monitoring of communications without notifying the target that he is under surveillance. After the signal has been monitored, it is converted to a digital signal for transmission. A method is also provided for intercepting a signal transmitted between the target served by a fiber optic network and a subscriber, such that a monitoring device may be installed without alerting the target. | 01-27-2011 |

20160127050 | PAIRING DEVICE - A pairing device for establishing a secure wireless communication path between a first device having a first body-coupling communication interface and a second device having a screen. The pairing device includes a screen communication interface having a light sensor, which, in conjunction with the screen of the second device, allows definition of a light-based communication path for the transmission of a first pairing information from the second device to the pairing device, a calculator for generating a second pairing information once the first pairing information has been received by the pairing device, a second body-coupling communication interface, which in conjunction with the first body-coupling communication interface allows the definition of a body-coupling communication path for the transmission of the second pairing information from the pairing device to the first device, the second pairing information allowing the establishment of a secure wireless communication path between the first device and the second device. | 05-05-2016 |
20160134632 | SECURE INSTALLATION OF NETWORK DEVICES USING BEACONING SYSTEMS AND METHODS - Secure installation of a new device onto a home-control network uses pairing with an intelligent device. An intelligent device, such as a smartphone, receives a notification, such as optical pulses, audible tones, short-range radio frequency signals, a watermark, or a barcode, from an uninstalled network device over a second network other than the home-control network. The intelligent device reads and decodes a device key from the notification and sends the device key to a network controller via a third network. The network controller sends a message using the device key to the new device over the home-control network, where the message is formatted to deliver the network key to the network device to permit the network device to send and receive messages comprising the network key over the home-control network. | 05-12-2016 |
