Abstract
A system and method distributes encryption and/or authentication capabilities among route processors in a manner that allows route processors in a set of route processors to back each other up in case one or more of the route processors in the set fail.
Claims20
A method of performing at least one cryptographic function on a message comprising network routing information, the method comprising:
- receiving the message comprising routing information;
- performing at least one cryptographic function on the message responsive to at least one cryptographic parameter;
- and
- flooding at least one of the at least one cryptographic parameter to a plurality of neighbor devices.
A system for performing at least one cryptographic function on a message comprising network routing information, the system comprising:
- a crypto manager having an input operatively coupled for receiving the message, the crypto manager for performing at least one cryptographic function on the message responsive to at least one cryptographic parameter to produce a result and providing the result at a first output, and for providing at least one of the at least one cryptographic parameter at a parameter output;
- and
- a communication manager having an input coupled to the crypto manager parameter output for receiving the at least one cryptographic parameter, the communication manager for flooding to a plurality of neighbor devices via a network connection coupled to an output at least one of the cryptographic parameters received at the communication manager input.
A computer program product comprising a computer useable medium having computer readable program code embodied therein for performing at least one cryptographic function on a message comprising network routing information, the computer program product comprising computer readable program code devices configured to cause a computer to:
- receive the message comprising routing information;
- perform at least one cryptographic function on the message responsive to cryptographic parameters;
- and
- flood at least one of the at least one cryptographic parameter to a plurality of neighbor devices.
