Abstract: A universal authentication mechanism for authenticating a user to a service provider (SP) is disclosed. An application device (ApD) requests a service for the user from the service provider (SP) and performs a transmission of a user identity (S10) identifying the user to the service provider (SP). The service provider sends a request for confirmation of the user identity (S20) to an authentication server (AS). The request comprises the user identity and a service identity identifying the requested service. The authentication server (AS) sends a request for service authentication (S50) to the authentication device (AuD) for confirmation. Based on the result of an analysis (S80) of a service authentication confirmation (S60) received from the authentication device (AuD), the authentication server (AS) sends a confirmation of the user identity (S90) confirming the identity of the user to the service provider (SP), which grants service access (S100).

Abstract: The invention relates to method and device for improving the link configuration speed of high-latency links, such as circuit switched links or satellite links, that use chatty protocols, which require sequential configuration phases, such as standard PPP in accordance with RfC 1661. In the initial link configuration phase, a standard LCP packet is sent out, followed by at least one masked packet that will be discarded silently by a peer operating in accordance with the standard protocol, but whose contents will be processed by a peer operating in accordance with the invention. The initial standard LCP packet produces compatibility with the standard protocol, whereas the sending of masked packets containing configuration information (PAP, CHAP, ICPC, etc.
