Patent EP-0021401-A1 (EP)
Inventor: KONHEIM ALAN GUSTAVE
IPC: G06F21/12
Filed: 1980-06-24
Abstract: A method and apparatus whereby the senders and receivers of messages sent over a transmission system including a Host CPU may guarantee the integrity of the data content of the message and also the absolute identity of the sender. Each user of the system as well as the Host CPU contains an identical key-controlled block-cipher cryptographic device with data chaining for encrypting and decrypting messages as required, wherein each user has knowledge of only his own cryptographic key and wherein the Host CPU has access to the unique cryptographic keys of all users of the system stored in a high security storage area available only to said CPU. Stated very generally, the originator of a mesage A sends a message to a receiver B which includes a transaction or message portion X and a unique digital signature portion Y which is a function both of the message and the senders unique cryptographic key K A . The receiver then communicates with the CPU for verification of the signature Y. The CPU accesses the sender's key K A  from a secure memory and computes the digital signature Y utilizing the message portion X received from B and the key K A . Upon a successful verification of the signatures by the CPU, the CPU notifies B via an additional message that the signature of A is valid based on the data content of the message and the key K A . Based on the information received from the CPU, B may be certain that the signature and message originated with A and A may not later deny having sent   
    
     the message as it would be virtually impossible for the signature to be forged since it is a complex function of the message content itself. A may also be assured that B cannot alter the message as the signature would no longer be valid. 
     According to other aspects of the invention the interrupting of communications between A and B by an eavesdropper and the subsequent sending of stale messages is prevented. As a still further feature of the invention, an eavesdropper is prevented from sending the "forged" approval from the CPU to the receiver B.

Abstract: Single mode optical fibre for operation in the wavelength range 1.5 to 1.7 microns is made by depositing a cladding glass layer (51) and then a core glass layer (52) upon the bore of a silica substrate tube (50). The bore of the coated tube is then collapsed to form a solid cross-section optical fibre preform. The cladding glass has an index matching that of silica and either contains no oxide of phosphorus or the minimal amount to proved a low enough deposition temperature and high enough deposition rate to provide an acceptably low diffusion of hydroxyl groups from the material of the substrate tube. Optionally the deposition of the cladding may be preceded by the deposition of a diffusion barrier layer which may contain a higher proportion of oxide of phosphorus.

Abstract: A device comprising a unit (µD), preferentially of microcomputer type, which detects traffic and controls the functions of a PABX. A computer equipment (HD) is connected to or from a part of the unit for interworking with it. The computer equipment has a terminal (A,) at an operator's position, intercept or equivalent position, the terminal being arranged to display information relating to the PABX interception facility. A PABX extension enters information about his own interception by making a call by dialling a predetermined code. His number and the code are stored in the unit. A subsequent call to the self-intercepted extension causes the unit (µD) to trans- ferthe caller to an operator or other attendant and to give on a display on the terminal at the operator's or other attendant's position a standard information preprogrammed in the computer equipment ofthe extension number.

Abstract: L'indicateur est destine a la surveillance de l'histoire de la temperature en fonction du temps d'un produit surgele. Pour cela, on utilise l'effet de dependance de la vitesse de diffusion d'un liquide dans un corps cellulosique (1, 18) en fonction de la temperature. Comme corps, on utilise soit une bande de papier (1) emballee dans une feuille (5) etanche a l'humidite, soit une pilule de carton filtre (18) disposee dans une cavite cylindrique ou prismatique formee dans une matiere synthetique. L'une des extremites du corps est libre afin de pouvoir capter l'humidite. L'indicateur est active par sa mise en contact avec une reserve d'eau ou de glace du produit a surveiller. Cette reserve d'humidite est constituee soit par l'humidite du produit meme, soit par une reserve d'eau placee dans un enfoncement menage dans l'emballage. Le corps cellulosique (1) est pourvu d'une substance hydratee, soluble dans l'eau, de preference du chlorure de sodium et/ou de l'acide citrique. L'arrivee a la fin de l'indicateur est marquee clairement par un indicateur (4, 17) acide/basique. Pour pouvoir mettre l'indicateur en contact avec la reserve d'eau, juste avant que celle-ci soit congelee, la zone de contact (1a) du corps (1) est, dans une forme d'execution, impregnee avec une substance visqueuse, de preference avec du sucre. Pour eviter un changement de couleur premature de l'indicateur (4) par un processus de diffusion lorsque l'indicateur n'est pas active, une zone tampon est prevue.

Abstract: Polymerisation en suspension de monomeres vinyliques dans un milieu aqueux pour former des resines vinyliques destinees a etre utilisees dans la production de plastisols. Le procede est effectue dans un milieu aqueux utilisant un catalyseur a radicaux libres, en presence d'un acetate de polyvinyle hydrolyse (alcool polyvinylique) possedant un degre d'hydrolyse compris dans la plage entre environ 65% en environ 85% et un compose possedant un equilibre hydrophile-lipophile (HLB) inferieur a environ 3,5. L'aspect important du nouveau procede consiste en l'utilisation d'une rampe d'agitation, c'est-a-dire dans le changement du degre d'agitation en cours de reaction, et l'adjonction du catalyseur au milieu de reaction apres que celui-ci ait atteint la temperature de reaction a laquelle sont produites des particules de polymeres correspondant a des billes vitreuses denses et spheriques presentant un diametre moyen compris dans la plage comprise entre 10 et 100 microns environ. Les resines en suspension ainsi produites se melangent facilement et uniformement avec un plastifiant pour former des plastisols de faible viscosite qui sont stables, contiennent des particules de taille uniforme et convenable, et peuvent produire des films, ou des produits similaires, possedant une bonne clarte.

Abstract: The multiprocessor system enables rapid comparison of results determined from input data at the individual microprocessors. During a first phase of the comparison the results which are to be compared are transferred from the individual microprocessors to counters in connection logic components each of which is associated with an individual microprocessor. During a second comparison phase which is started by activating a comparison line to which all the connection logic components are connected via a bus driver, the counters are simultaneously started to count for periods of time each of which corresponds to the result which has been transferred to the respective counter. The comparison line is deactivated by the counter with which the longest counting period is associated. For the purpose of determining the deactivated state, the comparison line is connected to respective inputs of the connection logic components. An interrupt request is produced at that one of the microprocessors which is associated with the counter having the longest counting period. The multiprocessor system can be used, for example, to control the optimum operation of an elevator system.

Abstract: To make an optical memory device (10), an annular reflective information recording area (15) is formed on one surface of a disc-shaped subplate (11) which is rotatable about a central axis. Information is recorded on, or read from, the circular or spiral track (40) of the information recording area, the track being centred on the centre hole. On the same surface of the subplate is a position signal area (15') formed in part of the same material as that of the information recording area (15), but at a different position from the information recording area. As the device (10) is rotated, a given point (13') in the position signal area is detected and used as a time reference, so that the location within the track of information can be determined for recording or reproducing.
