Abstract: A testing device of display devices and a testing method thereof are disclosed. The testing device includes a first connecting interface, a processing module, and a memory module. The first connecting interface is pluggable and is connected to the display device. The processing module is electrically connected to the first connecting interface. The processing module provides the information of test items stored in the memory module to the display device through the first connecting interface when the testing device and the display device are being transported on a production line, so the display device performs an operation procedure according to the information of test items. The processing module generates a test result according to the operation procedure executed by the display device and stores the test result in the memory module.

Abstract: A communication system includes a management device of Internet of Thing (IoT) devices and an agent communicatively coupled between the management device of IoT devices and plural cloud servers. The agent receives identification information corresponding to a first IoT device, and obtains a key hash corresponding to the first IoT device from one of the cloud servers that corresponds to the first IoT device according to the identification information, and transmits the key hash to the management device of IoT devices. The management device of IoT devices encrypts management information by utilizing the key hash and transmits the encrypted management information to the first IoT device. The management information includes a control hash. The first IoT device decrypts the management information to obtain the control hash, and encrypts a message by utilizing the control hash, and transmits the encrypted message to the management device of IoT devices.
