Abstract
A system and method for strong authentication achieved in a single round trip is disclosed, which reduces the amount of time needed for a mobile node to be authenticated by the network. In an embodiment of the present invention, the, authentication time is approximately three times faster than for 3GPP.
Claims19
A method for strong authentication achieved in a single round trip, comprising:
- sending a random number to a mobile node (MN), wherein the random number is generated local to the MN;
- generating a MN signature using the MN, wherein the MN signature is generated using the random number;
- authenticating the MN to a network, wherein the network is a GPRS network;
- and
- authenticating the network to the MN.
2 more elements
A system for strong authentication achieved in a single round trip between a MN and a network, comprising:
- a mobile node (MN) that is configured to generate a MN signature in response to a random number received from a source within a domain local to a current position relating to the MN and send the MN signature to be verified;
- the authentication server located within a home domain associated with the MN that is configured to receive the MN signature, verify the MN signature, and in response to the verification of the MN signature that indicates that the MN is verified to the network, wherein the network is a GPRS network, return an authentication signature to the MN.
A system for strong authentication between a mobile node (MN) and a network, comprising:
- a means for generating a random number local to the MN;
- a means for sending the random number to the mobile node
- a means for generating a MN signature using the MN, wherein the MN signature is generated using the random number;
- a means for sending the MN signature to an authentication server within a GPRS network, and verifying by the authentication the MN signature;
- and in response to the verifying, generating an authentication signature and sending the authentication signature to the MN for verification.
