发明名称 CONTROL AREA NETWORK DATA ENCRYPTION SYSTEM AND METHOD
摘要 <p>A power machine is configured to carry an attachment which is detachably coupleable to the power machine. The power machine includes a supporting frame with an operating compartment from which an operator operates the power machine to actuate one or more actuators of the power machine. A sensing unit senses a change in an operating device of the power machine and generates data indicative of the change. A first controlling unit, positioned on and coupled to the power machine, receives the data from the sensing unit indicative of the change in the operating device, and generates in response a set of corresponding operating messages. An encryption module positioned on and coupled to the power machine uses a key to encrypt at least a first portion of the set of operating messages into encrypted messages. A first control-area-network (CAN) controller formats the encrypted messages into a CAN format, and the encrypted messages in the CAN format are transmitted over a CAN bus. At an attachment, the encrypted messages are received from the CAN bus, decrypted using the key, and used by a second controlling unit to execute instructions or acts.</p>
