Abstract:
A set of redundant industrial control system communications/control modules includes at least a first communications/control module and a second communications/control module. The first and second communications/control modules are configured to perform an authentication sequence including: transmitting a request datagram from the first communications/control module to the second communications/control module, the request datagram including a first nonce, a first device authentication key certificate, and a first identity attribute certificate; transmitting a response datagram from the second communications/control module to the first communications/control module, the response datagram including a second nonce, a first signature associated with the first and second nonces, a second device authentication key certificate, and a second identity attribute certificate; and transmitting an authentication datagram from the first communications/control module to the second communications/control module when the response datagram is valid, the authentication datagram including a second signature associated with the first and second nonces.

Claim (Index 18):
The communications/control module of  claim 17 , wherein the set of instructions further includes instructions to:\n verify the second signature associated with the first and second nonces by concatenating the first nonce and the second nonce, cryptographically verifying the second signature associated with the first and second nonces with a public device authentication key, and comparing the locally generated concatenation of the first nonce and the second nonce with a cryptographically verified concatenation of the first nonce and the second nonce.
