The invention relates to secure distributed execution of jobs. A processing unit, where the processing unit is one of a set of processing units of a system, the processing unit comprising: a processor; and a memory including instructions that, when executed by the processor while avoiding interrupting a controller that does not belong to the set of processing units, cause the processor to perform at least one iteration of (a) entering a trusted mode, (b) selecting a selected job to be executed by the processing units, and (c) transmitting the selected job to the set of processing units. The method comprises the steps of (a) selecting a job, (c) checking access control metadata related to the selected job, (d) entering an untrusted mode by the processing unit, (e) executing the selected job by the processing unit while complying with the access control metadata related to the job, and (f) resetting the processing unit.
本发明涉及作业的安全分布式执行。一种处理单元,其中该处理单元是系统的一组处理单元中的一个处理单元,该处理单元包括:处理器;以及包括指令的存储器,该指令当由处理器执行同时避免中断不属于该组处理单元的控制器时,使该处理器用于:执行以下步骤的至少一次迭代:(a)进入受信任模式,(b)选择要由处理单元执行的所选择的作业,(c)检取与所选择的作业相关的访问控制元数据,(d)由处理单元进入不受信任模式,(e)由处理单元执行所选择的作业,同时遵守与该作业相关的访问控制元数据,以及(f)重置处理单元。
