1. A storage area network resistant to spoofing attack comprising:

  • at least a first compute node having a port and a first storage node having a port;

    storage area network interconnect interconnecting the port of the first compute node and the port of the first storage node;

    a first hash function generator for providing an authentication code for a frame transmitted over the storage area network from the port of the first compute node;

    a first key table for providing a key to the first hash function generator, the authentication code being generated by applying a hash function to the key and to at least a portion of the frame;

    a second hash function generator for verifying the authentication code upon receipt at the port of the first storage node; and

    a second key table for providing a key to the second hash function generator, the authentication code being verified by applying a hash function to the key and to at least a portion of the frame, the key being selected according to a source identifier of the frame.
