As an optional implementation manner of the present invention, if the target terminal does not belong to a preset blacklist, the step 103 is executed; if the computation offload task is normal, execute step 104: and unloading the target terminal based on the calculation unloading request.
Illustratively, when the target terminal is not in the white list or the black list, the target terminal is a new terminal, whether the unloading task of the target terminal is normal needs to be judged, if the unloading task is normal, the unloading task is abnormal, a trust violation label is attached to the target terminal, the target terminal is marked as a trust violation terminal, and meanwhile, the score of the target terminal is reduced.
As an optional implementation manner of the present invention, the preset measurement factors include an interaction frequency, a task execution period, a memory utilization rate, and a channel number, and step 103 includes: judging whether the interaction frequency of the target terminal exceeds a first threshold value, if so, generating alarm information and reducing the reliability of the target terminal; if the interaction frequency of the target terminal does not exceed a first threshold, judging whether the task execution period of the target terminal exceeds a second threshold, if so, generating alarm information and reducing the reliability of the target terminal; if the task execution period of the target terminal does not exceed a second threshold, judging whether the memory utilization rate of the target terminal exceeds a third threshold, if so, generating alarm information and reducing the reliability of the target terminal; if the memory utilization rate of the target terminal does not exceed a third threshold, judging whether the channel number of the target terminal exceeds a fourth threshold, if so, generating alarm information and reducing the reliability of the target terminal; and if the number of the channels of the target terminal does not exceed a fourth threshold value, judging that the unloading task is normal. As shown in fig. 3, it is a flowchart for determining whether the unloading task is normal.
Illustratively, whether the offloading task of the target terminal is normal is judged by judging a metric factor of the target terminal, where the metric factor includes four indexes, i.e., an interaction frequency, a task execution period, a memory utilization rate, and a channel number, the interaction frequency is a sum of frequencies of the target terminal entering and leaving the network, the task execution period is a CPU period that the target terminal executing the offloading task needs to consume, the memory utilization rate is a memory that the offloading task needs to consume, the channel number is a historical channel number of the target terminal and an edge computing node and an allocated channel number, and when the target terminal is a new terminal, the channel number is only an allocated channel number. And when one of the four indexes in the measurement factors does not meet the corresponding threshold, the unloading task is abnormal, alarm information is generated, the target terminal is marked as a trust violation terminal, and the credibility of the target terminal is correspondingly reduced.
