Title: Systeme cryptographique a facteur d'inviolabilite non apparent
Inventor: SPRUNK ERIC
IPC: H04L9/06
Filed: 1996-07-26
Abstract: Un procédé et un appareil de génération de clés pour système cryptographique incluent un générateur de clés générant un sous-ensemble de clés à longueur réduite de clé à partir d'une clé cryptographique plus longue faisant B bits. Le sous-ensemble de clés est distribué de façon aléatoire sur une longueur de clé de B bits en utilisant un hachage secret ou une clé de distribution de façon à obtenir des clés cryptographiques présentant un facteur d'inviolabilité apparent plus important. Le facteur d'inviolabilité, qui dépend du nombre possible de clés différentes pour une longueur donnée de clé exprimée en nombre de bits, offre à un casseur de clé un niveau correspondant de difficulté de décodage. Quand on ne connaît pas la clé secrète de hachage, le facteur d'inviolabilité de la clé cryptographique semble s'élever à une valeur S égale à 2B, ce qui fait qu'un casseur de clé doit faire jusqu'à 2B tentatives au jugé pour trouver avec certitude une clé spécifique. Ce niveau de difficulté demandera normalement trop de travail de calcul au casseur de clé pour mettre à jour le système. Toutefois, quand on connaît la clé secrète de hachage, le facteur d'inviolabilité est notoirement moins élevé. On peut ainsi réduire le facteur d'inviolabilité à un niveau suffisamment bas pour qu'il soit conforme aux exigences administratives en matière d'exportation et d'importation, sans pour autant affaiblir le niveau de protection ni la résistance du système. L'invention permet ainsi d'adapter facilement un générateur (ou moteur) de clé cryptographique utilisable dans plusieurs pays exigeant différents facteurs d'inviolabilité.

Abstract: In a multi-media communication terminal apparatus, when a slow reproducing operation is commenced, a supply of video data transmitted via a co mmunication line is stopped. A video data decoding unit reproduces each image of screens plural times corresponding to the slow reproducing operation based upon the video data previously stored in a video data buffer memory. When the repeating reproduction for the respective screens by the plural times corresponding to the slow reproducing operation is accomplished and the reproducing operation of a new screen is commenced, a video data decoding unit issues an interrupt to a CPU. Upon issue of the interrupt, the CPU checks a data remaining amount of the video data stored in the video data buffer, and sends a request to transmit a predetermined amount of video data to a data transmission source when the checked data remaining amount is lower than, or equal to a reference amount. Since the remaining data amount is checked only when the video data for a single screen is consumed, a workload to execute the process operation is low.

Abstract: A flickerless television receiver displays image signals having the
horizontal/vertical scanning frequencies thereof increased to two times the
horizontal/vertical scanning frequencies of the broadcast signals to be received.
Flickerless display performance can be confirmed with a single television receiver
by generating signals to extract every other field for image displaying and showing
two kinds of image signals, namely double-speed image signal and extracted
image signal. A display unit displays double-speed image signals having
horizontal and vertical scanning frequencies of image signals increased to two
tunes by conversion, wherein extracted image signals formed by extracting every
other field or frame from screen images are generated and two kinds of images
formed of the double-speed image signals and extracted image signals are
simultaneously displayed on one screen.

Abstract: Antenna elements (20) are arranged at intervals "d" greater
than λ/2, e.g., 5λ. A signal received by an antenna element
(20) is sent by way of an antenna multiplexer (21) to a
receiver (23), where the signal is demodulated. The thus-demodulated
signal is sent to a phase-and-power detection
section (25), where a phase and power of the signal are
detected. On the basis of the result of such detection, a
control section (26) calculates the phase and power of a
transmission signal. On the basis of the result of the
calculation, a transmission signal generation circuit (27)
transmits a transmission signal to each of the antenna
elements (20) by way of the antenna multiplexer (21).

Abstract: The double fourdrinier assembly, at a papermaking or cardboard prodn. machine to produce a fiber web, has a sharply angled downwards path for the double fourdriniers directly after the web forming roller (30) to develop a web from the pulp flow. The downwards fourdrinier path is at an angle (a) to the theoretical vertical of 10-50 degrees and pref. ≤ 45 degrees . A deflection unit (42) moves the path of both fourdriniers (11,12) for the downwards and angled alignment into the horizontal or a slight incline. The angle of the fourdrinier path round the web forming roller (30) can be varied by a swing movement at the stock inlet and the breast roller for the upper fourdrinier (12) round the rotary axis of the roller (30). A curved shoe structure (36), for the web development, lies at the upper fourdrinier (12) on its downwards path, opposite at least one deflector at the lower fourdrinier (11) or pliable bar (38) pressed against it. At least one pliable bar is pressed against the upper fourdrinier (12) at the circumference of the web development roller (30). An equal pressure water extraction stage is at the angled downwards path of the fourdriniers, with a static section against one fourdrinier (12) while the other section is pressed against the other fourdrinier (11) at an adjustable pressure, using plates or plate segments in both sections. The water extraction unit is permeable to liquid, and pref. perforated. In another form, the two fourdriniers (11,12) within the double fourdrinier zone are only in contact with static water extraction units (36,37) apart from the roller (30). A suction unit is at the lower fourdrinier (11) at the fourdrinier separation point on the downwards path. After separation, the lower fourdrinier (11) continues on an angled and downwards path, and pref. over a further water extraction unit, and the web is picked off (8,9) from the lower fourdrinier (11). At the end of the downwards fourdrinier path, the two fourdriniers (11,12) pass round a suction roller within the loop of the upper fourdrinier (12), and a lower suction system separates the lower fourdrinier (11) and the web from the upper fourdrinier (12). The double fourdrinier can be free of web forming bars. Directly after the web development roller (30), a pref. perforated guide plate with a convex curvature can be at the upper fourdrinier (12).

Abstract: A transmission power control apparatus includes a
transmission power control loop (1, 2, 3, 6, 9) provided
in one of a gateway station (12) and a terminal/mobile
station (13) for controlling a transmission power of the
station. The transmission level during transmission is
monitored and compared with a preset transmission level
to change over an average time for sampling of the error
between the transmission levels to vary the response
speed of the transmission power control loop (1, 2, 3, 6,
9). When the channel to be currently used is to be
changed over from a signalling channel (15) to a
communication channel (16), the transmission power is
controlled so that synchronization maintenance is
achieved at the receiving end. But, when the channel is
to be changed over from the communication channel (16) to
the signalling channel (15), the transmission power is
controlled rapidly to a standard level so that
synchronization acquisition or data transmission is
achieved with minimum trouble.
