Abstract: A system for accessing a packet-switching network (4), which is adapted for the use of a simplified signature method. The system includes a supplementary server (60) which is independent of a proxy server (50) of an access provider (12) and a simplified signature module (66) which is provided in the supplementary server (60). The proxy server (50) is equipped with an interface (64) which enables the connection of the proxy server to the supplementary server (60) and the transmission of at least the authentication requests sent by contacted service providers to the supplementary server (60) in order for the requests to be processed by the simplified signature module (66).

Abstract: A method of and module for masking application processing applied to a request for access to a server by a client workstation connected via successive proxy servers. The application of a first proxy server, is executed, the address of the client workstation is inserted into a specific data field of the access request message header, without calling for any IP spoofing function and the access request message for execution of successive application processing is sent to successive proxy servers. After execution of its application processing by a last proxy server and transmitting of the access request message to the server, the access request message is intercepted at a masking module, the specific field from the header is eliminated to mask the application processing, and a masked access request message is constructed and the masked access request message is sent from the masking module to the server.

Abstract: The invention concerns distributed DNS resolution of a DNS request comprising an FQDN domain name between terminal (T) and relevant parent server (SPP). The method consists in transmitting (A) a DNS request (r_DNS) to an extended intermediate relay server (SRE), and, in the absence of stored previous DNS resolution solution, inserting (B) in the request a DNS resolution extension variable (VE) to generate an extended DNS request (er_DNS), transmitting (C) the extended request to the parent server. Upon verification of the variable, searching (D) for a distributed DNS resolution agent (A_R_D), transmitting (E) an extended DNS reply EA DNS, containing the agent (A_R_D) to the relay server, executing (F) the agent to generate a DNS reply (A_DNS@IP) comprising at least the (FQDN) IP address and transmitting (G) the reply A DNS(?IP) to the terminal. The invention is applicable to DNS resolution on IP local area network or on the Internet.

Abstract: In this method of sharing personal attributes of a user between several on-line services providers, a Proxy server of an Internet access provider spliced into the flow between the terminal and the world wide web, intercepts an attributes request addressed to a user terminal and redirects it automatically to a personal attributes provider selection module. The Internet access provider is the one that dynamically assigned an Internet address to the terminal so that it can browse the world wide web.

Abstract: The invention relates to a method for distinguishing an HTTP request sent over a telecommunications network from a client device equipped with a browser to a Web server, characterised in that the HTTP request is marked when said request is sent explicitly by the user. Thus, the invention makes it possible to distinguish between explicit user requests and implicit browser requests for the purpose of operating in the network.
