An industrial device is configured to implement a lightweight file authentication sequence that rapidly verifies the integrity of mobile code supplied to the industrial device. The industrial device generates a file authentication code (FAC), which is stored on the industrial device and only made accessible to users via a local connection to the industrial device. The device-specific file FAC is installed on the program development application used to develop or edit the mobile code to be executed on the industrial device. The development application provides the mobile code to the industrial device together with a hash-based message authentication code (HMAC) generated using a retrieved copy of the FAC. The industrial device only permits execution of the mobile code if the HMAC included with the mobile code matches a locally created HMAC generated by the industrial device based on the mobile code and the device's local copy of the FAC.

Rapid file authentication on automation devices

The present invention provides for a handle set for a lock with a latch, the handle set having an authentication circuit and actuator in the interior handle that allow access to authenticated transponders. The present invention also provides a device and method for transmitting a rotational movement and force in an electronic lock, wherein the transmission takes place in a coupled state and not in a decoupled state and wherein the transmission of force does not damage an actuator that requires little energy to change between the coupled and decoupled states. A coupling cartridge of an electronic lock can easily be handed. The electronic lock can be retrofitted in installed mortise locks and used with cylindrical locks. The electronic lock can include a security feature that prohibits the electronic lock from changing between the coupled and decoupled states.

An electronic access control device with an actuator that requires little energy to change between the coupled and decoupled states. The actuator can have levers that interact to bias the control actuator in the decoupled state. The actuator can be changed between coupled and decoupled states by magnetizing and demagnetizing an armature that interacts with the levers. The electronic lock can include a security apparatus that prohibits the electronic lock from changing between the coupled and decoupled states when an external magnetic field is applied.
