Zusammenfassung:The embodiment of the invention provides a distributed multi-party secure computing system and method. The system comprises at least two TEE computing parties, and different computing tasks included in multi-party secure computing are allocated to different TEE computing parties; each TEE computing party comprises at least one TEE node; the at least one TEE computing party comprises at least two TEE nodes; TEE nodes in different TEE computing parties communicate through a multi-party secure computing protocol; and at least two TEE nodes in the same TEE computing party respectively execute one sub-calculation task in the computing task allocated to the same TEE computing party. The performance of multi-party secure computing can be improved. 本说明书实施例提供了一种分布式多方安全计算系统及方法。该系统包括至少两个TEE计算方,不同TEE计算方被分配有一次多方安全计算中包括的不同计算任务;其中,每一个TEE计算方中均包括至少一个TEE节点;且,至少一个TEE计算方中包括至少两个TEE节点;不同TEE计算方中的TEE节点通过多方安全计算协议进行通信;同一个TEE计算方中的至少两个TEE节点分别执行该同一个TEE计算方被分配的计算任务中的一个子计算任务。能够提高多方安全计算的性能。
