The invention discloses a multi-party privacy computing method, device and equipment and a computer readable storage medium, and the method takes a hardware acceleration card (such as an FPGA computing card) as a carrier to realize privacy computing, can realize data encryption / decryption in the hardware acceleration card of a data provider server, and can realize multi-party privacy computing. And the encrypted data is sent to the hardware acceleration card of the privacy calculation party server, the hardware acceleration card on the privacy calculation party server carries out decryption, corresponding privacy calculation is executed, and an encrypted privacy calculation result is returned. The hardware acceleration card and the server are isolated in hardware, so that the privacy and security of data can be ensured through isolation in hardware. In addition, data encryption / decryption and safe calculation are achieved through the hardware acceleration card, the data communication cost can be effectively reduced, and the calculation performance is further improved.
Description
technical field [0001] The present application relates to the field of secure computing, and in particular, to a method, device, system, and computer-readable storage medium for multi-party privacy computing based on a hardware accelerator card. Background technique [0002] Privacy computing refers to a series of information technologies that analyze and calculate data on the premise of ensuring that the data provider does not leak the original data, so as to ensure that the data is "available and invisible" in the process of circulation and integration. Currently, commonly used technologies for implementing privacy computing include: 1) Secure Multi-party Computation (MPC); 2) Federated Learning (FL); and 3) Trusted Execution Environment (TEE, Trusted Execution Environment) Wait. [0003] However, the above scheme has the problems of high computational and communication overhead and poor performance. Using a trusted execution environment also requires using vendor-specif...
