Apparatus and method for using certificate data to route data
First Claim
1. A method of routing data across a network, the method comprising:
- receiving, at a receiving node within a local network having a plurality of nodes, a session request from a client node to access, during a session, at least one node in the local network;
receiving a client certificate from the client node, the client certificate having client information comprising a public key of the client node and specifying at least one node to receive packets from the client node;
receiving from the client node a signature encrypted according to a private key of the client node;
executing an authentication process using the client certificate, wherein the authentication process includes using the public key to verify the signature;
retrieving the client information from the client certificate; and
if the authentication process authenticates the client node, routing data packets received from the client node to at least one node in the local network as specified by the client information in the client certificate, routing comprising maintaining a static connection between the receiving node and the at least one node in the local network, and routing data packets from the client node along the static connection, wherein handshake processes are not performed between the client node and the at least one node in the local network during the session.

Abstract
A method of routing data across a network receives a session request from a client node to access at least one node in a local network having a plurality of nodes. The method also receives a client certificate (e.g., a digital certificate at least partially specified by known standards, such as the “X509 Standard”) from the client node. The client certificate has client information specifying at least one node to receive packets from the client node. Next, the method uses the client certificate to execute an authentication process. If the authentication process authenticates the client node, then the method routes data packets from the client node to at least one node in the local network as specified by the client information in the client certificate.

15. A network routing device for routing data received across a network, the network device comprising:
-
a hardware interface for receiving a) a session request from a client node to access at least one node in a local network having a plurality of nodes, b) a client certificate from the client node, the client certificate having client information comprising a public key of the client node and specifying at least one node to receive packets from the client node and c) from the client node a signature encrypted according to a private key of the client node; an authenticator operatively coupled with the interface, the authenticator being configured to retrieve the client certificate and execute an authentication process using the client certificate, wherein the authentication process includes using the public key to verify the signature; and a router operatively coupled with the authenticator, the router being configured to determine, from the authenticator, if the authentication process authenticated the client node, the router further being configured to; maintain a static connection between the network routing device and the at least one node in the local network; and route data packets received from the client node to at least one node in the local network as specified by the client information in the client certificate if the client node is authenticated, wherein handshake processes are not performed between the client node and the at least one node in the local network during the session. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A computer program product for use on a computer system for routing data across a network, the computer program product comprising a tangible, non-transient computer usable medium having computer readable program code thereon, the computer readable program code comprising:
-
program code for receiving, at a receiving node within a local network having a plurality of nodes, a session request from a client node to access at least one node in the local network; program code for receiving a client certificate from the client node, the client certificate having client information comprising a public key of the client node and specifying at least one node to receive packets from the client node; program code for receiving from the client node a signature encrypted according to a private key of the client node; program code for executing an authentication process using the client certificate, wherein the authentication process includes using the public key to verify the signature; program code for retrieving the client information from the client certificate; and program code for routing data packets received from the client node to at least one node in the local network as specified by the client information in the client certificate if the authentication process authenticates the client node, routing comprising maintaining a static connection between the receiving node and the at least one node in the local network, and routing data packets from the client node along the static connection, wherein handshake processes are not performed between the client node and the at least one node in the local network during the session. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
