| 摘要 |
The description is of a procedure that allows temporary secure access to a communication network. The network has a number of network connection ports. Certain of these ports are termed confidential, that is, their access is controlled by the network operator, in contrast to the other connection ports access to which is free. The access procedure claims is based on the provision of two distinct services accessible via tunnels that are, advantageously, digital. The first service is accessible only from the confidential connection ports and only allows a connection credit to be obtained. The second service is accessible from all connection ports, only by means of the connection credit issued by the first service. |

1. Procedure for accessing a data network via a terminal, by creating a tunnel from said terminal to an operational service, using a connection credit, said procedure comprising:
A stage (2.1) of connecting the terminal to a port of said data network, A stage (2.2) of creating a tunnel to a configuration service, A stage (2.3) of obtaining a connection credit from the said configuration service, A stage (2.6) of creating a tunnel to said operational service in order to access this service using the connection credit obtained from the configuration service, wherein in step (2,1), said terminal is connected to a physical dedicated network connection port (12), called a confidential port, said confidential port (12) being the sole physical port amongst a plurality of physical ports (13) of said data network dedicated to authorize the access of the connected terminal to said configuration service by using the tunnel created in step (2.2) in contrast to the other ports (13) of said plurality of physical ports which do not authorize said access. |
