For example, a data processing device may be provided with 64 expansion interfaces, wherein 32 expansion interfaces are respectively connected with an encryption device, that is, 32 encryption devices. If the computing power demand of the current user exceeds the computing power of the current data processing equipment, one or more new encryption devices can be inserted in a non-shutdown state to improve the computing power of the data processing equipment.
In one illustrative example, each encryption device includes a secure memory chip;

and selecting the encryption device as a target from all encryption devices according to the load information of each encryption device, and sending the received data to the encryption device as the first target.
In an exemplary example, the selecting, from all encryption devices, an encryption device as a first target according to load information of each encryption device, and transmitting the received data to the targeted encryption device includes:
and selecting the encryption device with the lowest load according to the load of each encryption device, and sending the received data to the encryption device with the lowest load.

Assume scene one is: the data acquisition end sends the video data acquired by the camera to the data processing device of the present example through the network channel for processing, and the following description takes a scene one as an example to illustrate the working principle of the data processing device as follows:
after the data processing equipment is started, loading load balancing software and security module mutual trust software in a memory into a processor;
step two, the processor carries out safety verification on all safety modules through safety module mutual trust software, and if all the safety modules are credible, the processor executes step three; and if any security module is not credible, the buzzer alarms and sets the data processing equipment to be in an unavailable state.
Loading a safety module by the processor;
step four, the number 0 security module generates a key and synchronously sends the key to each other security module;
step five, the processor loads all the security modules into a usable state;
step six, after receiving the video data, the network interface sends the video data to the processor;
step seven, the processor determines the safety module with the lowest current load;

secondly, the existing single encryption machine cannot realize disaster recovery, and when a fault occurs, two encryption machines are needed to realize disaster recovery operation. The data processing equipment of the example comprises a plurality of security modules, disaster recovery of the secret key can be automatically realized among the security modules, and after a certain security module is invalid, the data processing equipment can still continue to operate without adding extra hardware equipment, so that the user cost can be reduced;
third, the present example may dynamically adjust the number of security modules based on computing power, and when the current computing power demand of the user exceeds the computing power of the current data processing apparatus, a new security module may be inserted without shutdown to increase computing power. Compared with the scheme of adding the encryption machine when the current computing power is insufficient, the scheme has lower cost and simpler operation.
