Title:
UNIVERSAL LIGHTWEIGHT HASH PROCESSING METHOD AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/007506
Kind Code:
A1
Abstract:
Disclosed in the present invention are a universal lightweight Hash processing method and system, and a storage medium. The method comprises: selecting a linear feedback shift register, and performing status transition on the linear feedback shift register by using a register status transition function; initializing an internal status of a Hash algorithm by using an output of the linear feedback shift register in conjunction with an initialization algorithm; inputting data requiring to calculate Hash values, and updating the initialized internal status by using an updating algorithm, wherein the data requiring to calculate Hash values is filled data; and performing post-processing on the updated internal status by using a determination algorithm to generate a final Hash value. The problems of speed and security of the existing Hash processing are solved, the implementation is simple, a length and a starting point can be flexibly adjusted, parallel and rapid calculation is facilitated, the required storage space is small, a calculated Hash word can be dynamically added to eliminate collision when Hash collision occurs, and the security is improved.
