DATA DISTRIBUTION STORING AND RESTORING METHODS AND APPARATUSES

摘要

PURPOSE: A data distribution, storage, and restoring method and apparatus thereof are provided to effectively minimize redundancy by performing secret diffusion about clear text data. CONSTITUTION: A seed buffer(120) stores a seed value from padding which is generated by a padding generation unit. An allocation unit(130) divides clear text data into allocation values based on the padding. An arranging unit(140) arranges the allocation values according to the size of allocation using an ascending order and a descending order. An XOR calculation unit(150) calculates the allocation value of the arranged clear text data. The XOR calculation unit perform an XOR calculation about the result value of inverting.
