According to some embodiments, an overall chain-of-trust may be established for an industrial control system. Secure hardware may be provided, including a hardware security module coupled to or integrated with a processor of the industrial control system to provide a hardware root-of-trust. Similarly, secure firmware associated with a secure boot mechanism such that the processor executes a trusted operating system, wherein the secure boot mechanism includes one or more of a measured boot, a trusted boot, and a protected boot. Objects may be accessed via secure data storage, and data may be exchanged via secure communications in accordance with information stored in the hardware security model.

Secure industrial control platform

A system and method for controlling processor instruction execution. In one example, a method for synchronizing a number of instructions performed by processors includes instructing a first processor to iteratively execute instructions via a first set of iterations until a predetermined time period has elapsed. A number of instructions executed in each iteration of the first set of iterations is less than a number of instructions executed in a prior iteration of the first set of iterations. The method also includes instructing a second processor to iteratively execute instructions via a second set of iterations until the predetermined time period has elapsed. A number of instructions executed in each iteration of the second set of iterations is less than a number of instructions executed in a prior iteration of the second set of iterations. The method includes determining whether additional instructions are to be executed.

System and method for synchronizing processor instruction execution

A system and method for controlling processor instruction execution. In one example, a method for controlling a total number of instructions executed by a processor includes instructing the processor to iteratively execute instructions via multiple iterations until a predetermined time period has elapsed. A number of instructions executed in each iteration of the iterations is less than a number of instructions executed in a prior iteration of the iterations. The method also includes determining the total number of instructions executed during the predetermined time period.

Controlling total number of instructions executed to a desired number after iterations of monitoring for successively less number of instructions until a predetermined time period elapse
