Integrity Check Method for Fine-Grained Data Based on Complex Rotary Codes
Guoyin Wang · Journal of Southwest Jiaotong University · 2009
To overcome the shortcoming of the existing integrity check methods for fine-grained data and improve the error indication capability,a novel multiple-error indicating method based on the complex rotary codes was proposed.This method checks the integrity of data objects via cross-checking with grouped Hashes,where each group Hashes can indicate the integrity of all data independently.Analysis and experiment results show that the proposed method can compress Hash data effectively,and its base error amplification ratio reaches almost 1,much lower than that of the existing check methods.
