Embodiment 2

[0124] Embodiment 2 of the present invention provides a data processing method, such as diagram 2-1 , 2-2 shown, including the following steps:

[0125] In step 201, the CPU detects a data processing signal.

[0126] In step 202, the CPU judges whether a data processing signal is detected, and if a data processing signal is detected, executes step 203; otherwise, returns to step 201.

[0127] In step 203, the CPU initializes the data in the first storage area, the second storage area and the third storage area.

[0128] Specifically, the CPU may set the data in the first storage area, the second storage area, and the third storage area to 0x00, wherein the size of the first storage area may be 64 bytes for storing intermediate data; the size of the second storage area may be 20 bytes, and is used for storing the intermediate data of the output data; the size of the third storage area may be 20 bytes, and is used for storing the result of the output data.

[0129]Step 204,...

Embodiment 3

[0209] Such as image 3 As shown, it is a structural diagram of a data processing device in Embodiment 3 of the present invention, including a detection module 310, a first judging module 320, a first processing module 330, a second processing module 340, a second judging module 350 and a second judging module 350. Three processing modules 360 .

[0210] Wherein, the detection module 310 is configured to detect the data processing signal.

[0211] The first judgment module 320 is configured to judge whether the detection module 310 has detected the data processing signal, and trigger the first processing module 330 when the detection module 310 detects the data processing signal;

[0212]The first processing module 330 is configured to initialize the data in the first storage area, the second storage area and the third storage area; copy the data in the fourth storage area to the first storage area, and Perform an XOR operation on the data in the first storage area and the f...

Abstract

The invention discloses a data processing method and device. The method comprises the following steps of: detecting a data processing signal; judging whether the data processing signal is detected or not, if so, initializing the data in part of the storage areas; writing data in the initialized storage area and carrying out a series of operation on the data in the storage area and a preset value; reading the data with one byte from the storage area for storing an operation result, using the value of the read data with one byte as the index, and reading the data with a preset amount of bytes from the storage area for storing the operation result; and outputting the data processing result according to the read data with the preset amount of bytes. By the method and device, one or more groups of data with different lengths and formats can be integrated and processed, and the data with fixed length and fixed format can be output, so that the data processing efficiency is improved, and the output data has the characteristics that the randomness is good, the processing process is irreversible and the like.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] Data is a representation of facts, concepts, or instructions that can be processed by human or automated means. Data can be in the form of numbers, text, graphics or sound, etc., and after being interpreted and endowed with certain meanings, the data becomes information. Data processing is the collection, storage, retrieval, processing, transformation and transmission of data, which runs through all fields of social production and life. Data that is valuable and meaningful to certain people. [0003] In information security technology, hash (Hash) functions are often used to verify the integrity of messages. The hash function processes input information of different lengths to obtain output information with a fixed length, and the output information with a fixed length is a hash or a message digest of...
