  • Patent number: 5867577
    Abstract: A method and an apparatus for authenticating a data carrier enables a transaction or access to a service or a location, and the corresponding carrier. The carrier (1) has a specific number (Ns) and an authentication value calculated from the specific number and from information (I) that defines the rights attaching to the carrier by means of an asymmetrical algorithm (F) and a secret key (Ks). Two types of authentication are provided. One is current, in a mode disconnected from the authorizing organization. The other is periodic, in a connected mode. In the disconnected mode, an algorithm (G) correlated with the asymmetrical algorithm (F) and using a public key (Kp) is applied to the authentication value (VA), read from the carrier, in order to verify that the authentication value (VA) is compatible with the specific number (Ns) and the information (I), and that the transaction or service requested is compatible with the information (I).

  • Patent number: 5867639
    Abstract: Data validation uses redundant storage of the data on two-layer magnetic tapes. A method and system provide data recording and reading on such magnetic tapes with a high degree of protection from errors and/or fraudulent behavior. The two-layer tape includes a first layer with a high coercive field positioned on a support and a second magnetic layer with a lower coercive field covering the first layer. Synchronous recording is done on the two layers so that all data is recorded on the second layer and some of the date is recorded on the first layer. Data on the second layer is validated upon reading by reading the data in the first layer after erasure of the second layer.

  • Patent number: 5848109
    Abstract: A process and apparatus for sampling a serial digital signal (D), which includes phasing of the digital signal with a clock signal (C) and sampling the digital signal at delayed instants (Si), wherein the phasing is carried out in reference to the sampling instants. The phasing includes determining phasing test instants (Pi) which refer to the sampling instants (Si) to verify whether transitions of the digital signal are leading or lagging in phase relative to the phasing test instants. The determination of the phasing test instants is achieved by adding to each sampling instant (Si) a delay Y=kR/2, in which k is a positive whole odd number other than zero and R designates a pulse repetition period of the bits of the digital signal (D). The invention has particular utility in data processing and remote data processing systems, and to telecommunication systems.

  • Patent number: 5841871
    Abstract: A method for authenticating a user working in a distributed environment in the client/server mode, wherein each authentication is performed from a single piece of authentication information, known as the "passphrase", having a predetermined length and duration of use (as a function of a tally value). The method is applicable to either a one-time password (OTP) system or an OTP system integrated with a Kerberos system, or in a one-time password system used alone, and the method may be used from a trusted terminal or an untrusted terminal. A method is provided that enables reinitializing the "passphrase" at the end of the duration of use with security, even in the event of active interception, and either in an OTP system integrated with a Kerberos system, or in an OTP system used alone.

  • Patent number: 5836407
    Abstract: The invention relates to a tool for drilling oil, gas or geothermic wells. The tool includes two main members, a hollow shaft (1) and a blind tool body (2) more elongate than conventional tool bodies; the two main members are spherically connected to each other by means of a ball joint (4,5). The ball joint is located at the very bottom of the blind portion of the tool body which carries a stabilizer (19) at the other end. The tool is also provided, between the hollow shaft and the tool body, with an appropriate transmission system (6, 7, 8, 9, 11), which is spaced apart from the ball joint and situated between the latter and the stabilizer. The essential advantage of the tool lies in the relative position of the ball joint and the stabilizer, the positioning conferring on the tool a favorable dynamic behavior, without risk of buttressing. Field of application: drilling of oil wells, gas wells and geothermic wells.

  • Patent number: 5833332
    Abstract: The invention relates to a novel furniture frame system comprising horizontal and vertical frame members which can be arranged in a variety of configurations to provide at least one continuous concealed channel for cables such as power and/or signal cables, in which the channel is easily accessible for wiring, maintenance, rearrangement and storage of cable without disassembly of the frame system and provides for access to cable outlets at work surface height so that cable devices can be connected to an outlet with minimal interference to the work surface. The frame system itself does not interfere with the work surface. The horizontal frame member has an opening on the top surface which is at work surface height for access to the cable channel, and also has a cover for the opening which has at least one flexible edge to enable cables to pass in and out of the channel when the cover is closed and permits the cable to move freely along the length of the cover.
