Title:
ENCRYPTION KEY GENERATION MODULE FOR PROTECTING DATA SECURELY
Document Type and Number:
WIPO Patent Application WO/2020/067616
Kind Code:
A1
Abstract:
The present invention relates to an encryption key generation module for protecting data securely, which: extracts a table corresponding to a numerical value which is the sum of all data of a plurality of tables mod the number of the tables and then sets, as a position value and a key, a numerical value which is the sum of data of the extracted table mod the size of the table; and combines, with data, keys generated by repeating the position value and the key by the same method as long as the length of the key so as to encrypt, sign, and then store the keys. Accordingly, the present invention has the effects of: data being safely stored and being safe from being exposed to the outside as the data is encrypted; data being protected securely due to random numbers configured such that keys for encrypting the data are generated differently for each device; and a key retrieval process being very fast as the key is retrieved through the modulo operation.
