Implementation method and device for data feature calculation consistency, equipment and storage medium

Abstract

The invention provides a method for realizing data feature calculation consistency under a mimicry architecture, which comprises the following steps of: respectively carrying out packet cutting and segmentation on a data message issued by each heterogeneous processor to obtain a plurality of sub-packets, wherein the packet cutting principle is that the contents of a plurality of cut sub-packets issued by the same data message from each heterogeneous processor are the same, but the sub-packet sequences are allowed to be different; performing digest algorithm processing on each sub-packet to obtain a sub-packet feature value of each sub-packet; and respectively carrying out accumulation processing and XOR processing on the sub-packet characteristic values of the sub-packets issued by the same data message from the heterogeneous processors, and then carrying out abstract operation processing to obtain the whole packet characteristic value of the whole data message. According to the method, packet cutting processing is carried out on the data issued by the heterogeneous CPU in the mimicry mode, the coverage content of each sub-packet is the same, disorder among the sub-packets is supported, exclusive or and accumulation operation is carried out on the extracted sub-packet feature values, disorder of feature data of each sub-packet can be tolerated, and the problem of inconsistency of the data issued by the heterogeneous processor is solved.

Description

technical field [0001] The invention belongs to the technical field of data message verification, and in particular relates to a method, a device, a device and a storage medium for realizing the consistency of data feature calculation under a mimetic architecture. Background technique [0002] In practical applications, with the emphasis on data security, the trend of data security in the mimetic mode is more and more obvious. [0003] The characteristic value of the entire packet of the message is used to distinguish the consistency of the packet data in different packets. Under the mimic architecture, it is necessary to compare whether the contents of the packet data in different packets are consistent. By calculating the characteristic value of the entire packet, compare different packets. The characteristic value of the entire packet of the text is equivalent to comparing whether the contents of the packets in different packets are consistent. [0004] In the prior art,...

Problems solved by technology

[0006] In view of this, the present invention aims to propose a method, device, device, and storage medium for realizing the consistency of data feature calculation under the mimetic architecture, which can realize the whole package feature for the data message sent by the CPU processor under the mimetic environment. Extraction, which solves the problem that the results of feature calculation are different due to the fact that the messages with the same attributes issued by each processor in the heterogeneous mode have inconsistency differences
