发明名称 Industrial Protocol System Authentication and Firewall
摘要 Aspects of the present invention provide machines, systems, and methods in which industrial control systems may be secured from compromise and/or disruption via authentication and firewall. In particular, an industrial controller may: randomly generate an exchange key and send the exchange key to a client device in response to a transaction request originating from the client device; combine the exchange key with a locally stored pass key to produce an authentication code; and compare a challenge key received from the client device to the authentication code to determine a match between the challenge key and the authentication code. A successful match between the challenge key and the authentication code may allow the client device to further access the industrial controller using a common industrial protocol (CIP), and a failed match between the challenge key and the authentication code may prevent the client device from further access to the industrial controller.
