Classification: CPC H  G | IPC G  H

Claim 0:
1. A hash algorithm circuit, comprising:
an input circuit unit, configured to receive data to be processed;
at least one hash circuit unit, electrically coupled to the input circuit unit, wherein the hash circuit unit has a circuit structure arranged according to a preset hash algorithm, and is configured to form the data to be processed, passing through the hash circuit unit, into a target data, wherein a data length of the data to be processed is greater than a data length of the target data;
an output circuit unit, electrically coupled to the at least one hash circuit units, and is configured to output the target data; and
a first hash circuit unit and a second hash circuit unit, wherein:
the first hash circuit unit is electrically coupled to the input circuit unit, and the first hash circuit unit has a circuit structure arranged according to a first preset hash algorithm, and is configured to form the data to be processed into an intermediate data, wherein the data length of the data to be processed is greater than a data length of the intermediate data;
the second hash circuit unit is electrically coupled to the first hash circuit unit, and the second hash circuit unit has a circuit structure arranged according to a second preset hash algorithm, and is configured to form the intermediate data into the target data, wherein a data length of the intermediate data is greater than the data length of the target data;
the data to be processed is divided into n sequences;
the first hash circuit unit is configured to form, through its circuit structure, the n sequences into the intermediate data having k sequences according to the first preset hash algorithm, where n and k are both natural number, and n>k; and
the second hash circuit unit is configured to form, through its circuit structure, the k sequences into the target data having u sequences according to the second preset hash algorithm, where u is a natural number, and k>u.
