The invention discloses a distributed rendering device and system. The device comprises a network interface, a mainboard, a microcontroller unit, a digital signature chip and a graphics processor, wherein the network interface is used for receiving a rendering task sent by a task sending end and transmitting the rendering task to the mainboard; the mainboard is used for sending the rendering taskto the graphics processor through the microcontroller unit; the graphics processor is used for performing rendering according to the rendering task, generating a corresponding rendering result and sending the result to the microcontroller unit; the microcontroller unit is used for sending the rendering result to the digital signature chip; the digital signature chip is used for performing encryption processing on the rendering result, generating a first HMAC value and returning the value to the microcontroller unit; and the microcontroller unit is used for sending the first HMAC value and therendering result to a distributed network, so that the task sending end performs verification on the rendering result. According to the distributed rendering device and system in the invention, safetyof transmission of the rendering result output by the rendering device can be ensured, and the hazards of man-in-the-middle attacks and data tampering are avoided.
Description
technical field [0001] The present invention relates to the field of distributed networks, in particular to a distributed rendering device and system. Background technique [0002] Existing distributed rendering devices are of various types. Almost any device with an operating system can be used as a distributed rendering device, such as mobile phones, tablets, PCs, and workstations. For individuals, it is possible to increase the rendering speed by adding idle devices. For enterprises, large rendering tasks can be handed over to specialized cloud rendering companies. [0003] For individuals, the number of devices that can be added is limited, and external devices will not help with homework because they have no profit. For enterprises, it is bound to be more expensive to hand over the rendering tasks to a dedicated cloud rendering company because they need to pay for the company's operating costs. Therefore, the best distributed rendering system is that a large number ...
