Abstract:
PROBLEM TO BE SOLVED: To provide a security system based on a public key infrastructure PKI preventing an unauthorized person from using a main computer unit belonging to an authorized user. SOLUTION: The public key infrastructure PKI is constructed of a removable security part including a main secret key and a main PC public key, and a PC security area including an extractable PC secret key and an extractable main public key. After the removable security part, which is already removed, is inserted into a remote computer unit, mutual authentication between the removable security part and the PC security area is carried out, and a user authorized in this way can access data stored in the computer unit.

Abstract:
System for transferring a data file from a web server to a user workstation through a network and reciprocally, the user workstation including a hard disk ( 205 ) for storing the data file being transferred over a SCSI bus ( 208 ). The user workstation includes a dual-port memory ( 304 ) for storing temporarily the data file, a network logic unit ( 302 ) interconnected between the network and the input port of the dual-port memory for receiving the data file from the network and transmitting it to the dual-port memory, and a SCSI logic unit ( 303 ) interconnected between the output port of the dual-port memory and the SCSI bus for transferring the data file from the dual-port memory to the hard disk over the SCSI bus and reciprocally.
Abstract:
Assigning a dual address to a workstation in an IP data network composed of at least a first Local Area Network (LAN) provided with a home Dynamic Host Configuration Protocol (DHCP) server, a home Domain Name Services (DNS) server an a home registration server. Workstation parameters, including a statix IP address, and a longon ID and password, wich have been provided to the user of the workstation are registered into the registration server in an offline mode. The workstation is connected to the IP network in a DHCP mode. A dynamic IP address is provided to the workstation by the registration server. The home registration server is then called by the workstation to get the static IP address and, secondly a configuration file for the workstation. The applications to be processed by the workstation are then configured automatically with the static IP address or the IP address.
Abstract:
The assymetric digital subscriber line dynamic inversion system has central equipment (12) connected to a service network (10) with client equipment (26) connected to a client work post (32). The equipments are connected by a public telephone connection line (22). When high speed transmission is wanted a message inversion demand is set, activating the coding and decoding of the central equipment coding at a medium speed and decoding at a high speed. A message of reception is sent to the client equipment, activating coding and decoding at high speed in the client equipment, and transmitting a reception message back to the central equipment.
Abstract:
A method and system for dynamically inverting an A symmetric Digital Subscriber Line (ADSL) system. The ADSL system includes a central exchange equipment (CE) connected to a service provider network and a user equipment (UE) connected to a user workstation. The CE and UE are interconnected by a PSTN link. The CE includes an ADSL transceiver and a splitter coupled between the CE transceiver and the PSTN link. The splitter includes a low-pass filter for separating low frequency voice signals from high frequency ADSL signals transmitted from the UE. In accordance with the method of the invention, an invert request message encoded as a tone sequence is generated by the UE and transmitted to the CE over the PSTN link. The tone-encoded invert request is received through the CE splitter low-pass filter and is decoded utilizing a tone decoder communicatively coupled between the CE splitter low-pass filter and the CE transceiver.
Abstract:
Data transmission system for transmitting packets of data from a source workstation ( 10 ) to a destination workstation ( 18 ) wherein the packets of data are transmitted over at least an IP network ( 14 ) between an ingress node ( 16 ) connected to the source workstation and an egress node ( 20 ) connected to the destination workstation, wherein each router within the intermediary nodes along the data path from the ingress node to the egress node determines the best route in a routing table defined by the contents of a field contained in each packet of data being received. For this, the router of the ingress node comprises a configuration table which defines the contents of the TOS field in function of information associated with the 4/5 level protocol such as TCP or UDP.
Abstract:
The wireless communication system has two USB hubs (10,12), connected by wireless communication, with one connected to the host computer (16) and the other connected to a number of bidirectional ports (20). Each hub has a radio adapter (28,30) with an antenna (32,34) and a number of USB connectors.
Abstract:
The invention relates to a Universal Serial Bus (USB) with two wireless communication hubs (USB hubs). One of these hubs is connected to a first host computer, and both USB hubs are connected to a plurality of I/O devices. Each USB hub includes a wireless adapter and an antenna connected to the wireless adapter. The wireless adapter of each USB hub comprises a transmitting/receiving unit for transmitting data via the antenna to the wireless adapter of the other USB hub or receiving data via the antenna from the wireless adapter of the other USB hub. The wireless adapter also comprises a wireless dual port, which is automatically configured upstream or downstream when the first host computer is connected to one of the USB hubs.
