SECURE INDUSTRIAL CONTROL SYSTEM

摘要

A secure industrial control system is disclosed herein. The industrial control system includes a plurality of industrial elements (e.g., modules, cables) which are provisioned during manufacture with their own unique security credentials. A key management entity of the secure industrial control system monitors and manages the security credentials of the industrial elements starting from the time they are manufactured up to and during their implementation within the industrial control system for promoting security of the industrial control system. An authentication process, based upon the security credentials, for authenticating the industrial elements being implemented in the industrial control system is performed for promoting security of the industrial control system. In one or more implementations, all industrial elements of the secure industrial control system are provisioned with the security credentials for providing security at multiple (e.g., all) levels of the system.

主权项

1. A secure industrial control system, comprising:
an input/output module provisioned with a first unique security credential, the input/output module including a first memory device and a first processor coupled to the first memory device, the input/output module being operable to receive industrial sensor information or send control information to an industrial actuator or motor; and a control module provisioned with a second unique security credential, the control module including a second memory device and a second processor coupled to the second memory device, the control module being configured to monitor and control the input/output module, wherein the control module is configured to at least partially enable or disable operability of the input/output module based upon an authentication process performed with at least the first unique security credential.
