Problems solved by technology

[0006] Since multiple encryption cards may be encryption cards of different manufacturers, that is, the processing performance of different encryption cards may not be consistent. Therefore, when the data is evenly distributed to each encryption card, the processing performance of each encryption card cannot be fully utilized, that is, Said that the processing performance of the cryptographic card cannot be maximized

Abstract

The invention provides a heterogeneous cipher card parallel computing method, device and equipment, and the method comprises the steps: determining a target data length corresponding to a to-be-processed service, and querying an initial weight ratio corresponding to the target data length from a weight table; for each password card, determining a data volume needing to be processed by the password card based on the initial weight ratio, and issuing to-be-processed data matched with the data volume to the password card; wherein for each data length, the initial weight proportion corresponding to the data length is determined based on the initial weight, corresponding to the data length, of each password card; and for each password card, determining an initial weight, corresponding to the data length, of the password card based on test data generated in the test process of the password card. According to the technical scheme, the processing performance of each password card is fully utilized.

Description

technical field [0001] The present application relates to the technical field of data security, in particular to a parallel computing method, device and equipment for heterogeneous cryptographic cards. Background technique [0002] In order to effectively protect data, when data is stored, it is necessary to store the data after encryption, and correspondingly, the encrypted data also needs to be decrypted before use. During data transmission, the data needs to be encrypted before transmission, and correspondingly, after receiving the encrypted data, it also needs to be decrypted and used. [0003] Considering that both data encryption and data decryption require a large amount of computing resources, a cryptographic card is usually integrated in the device to realize data encryption or data decryption. As a kind of hardware encryption card and hardware decryption card, the cryptographic card can improve data encryption or The processing speed of data decryption has been wi...
