Title: Apparatus and method for secure communication based on channel characteristics
Inventor: HASSAN AMER A
IPC: H04L9/08
Filed: 1997-06-06
Abstract: PURPOSE: A communication secure apparatus and method are provided using characteristics of a communication channel to establish key sequences for use in encrypting communicated information. CONSTITUTION: The characteristics are the impedances of the channel viewed from one transceiver to the other and vice versa. The keys can be established with computations equivalent to a bounded distance decoding procedure, and the decoder used to establish a key may be used for processing the subsequent data transmission. Compared to classical and public-key cryptographic systems, an alternative mechanism for establishing and sharing key sequences that depends on a physical process is provided in which each party need not generate a pseudo-random quantity because the necessary randomness is provided by the properties of the communication channel itself. By using a channel decoder, the probability of two users establishing the same secret key is substantially unity, and the probability of an eavesdropper establishing the same key is substantially zero. Also, the number of possible keys is large enough that finding the correct one by exhaustive search is impractical.

IPC: G01B11/24
Filed: 1997-06-26
Abstract: PURPOSE: A fringe pattern discriminator for interferometer using diffraction gratings is provided to analyze the interferogram produced in the interferometer using a pair of diffraction grating, which separate and reunite both test beam and reference beam for measurement the surface of object. CONSTITUTION: The interferometer separates reference and test beams which can measure the total surface of object arranged between diffraction gratings.

An object fringe pattern is distinguished from other fringe patterns in an interferogram produced by an interferometer using a pair of diffraction gratings for separating and recombining test and reference beams. The object on which a test beam is incident is moved in X and Y directions in a plane perpendicular to an optical axis of the interferometer to change the brightness regions of the object fringe pattern. A computer identifies pixels whose irradiance changes in response to object movement, and then only irradiance data from the identified pixels is used in analyzing the interferogram to produce a measurement of a surface of the object.

The apparatus makes the illumination light incident onto the camera from the illumination reflector uniform.

Abstract: PURPOSE: A device for automatically cutting an invar-plate sticking in an insulating box of an LNG(liquefied natural gas) line is provided to install the invar-plate in the box by automatically cutting. CONSTITUTION: In turning on an operating switch, a motor(14) and a roller(24) are rotated by a control unit(70) to supply an invar-plate(42) toward a cutter(30). In detecting the invar-plate through a position detecting sensor, the cutter cuts the invar-plate by operating a second cylinder. Harmful materials are exhausted by an exhausting unit. The control unit cuts the invar-plate according to a signal from the position detecting sensor continuously.
