Abstract
(EN)
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.

La présente invention concerne un module de génération de clé de chiffrement permettant de protéger de manière sécurisée des données qui : extrait une table correspondant à une valeur numérique qui est la somme de toutes les données d'une pluralité de tables, mod le nombre des tables, puis définit, en tant que valeur de position et une clé, une valeur numérique qui est la somme des données de la table extraite, mod la taille de la table; et combine, avec des données, des clés générées par répétition de la valeur de position et de la clé par le même procédé que la longueur de la clé de façon à chiffrer, signer, puis stocker les clés. Par conséquent, la présente invention a pour effet : des données qui sont stockées en toute sécurité et qui sont à l'abri d'être exposées à l'extérieur lorsque les données sont chiffrées; des données étant protégées de manière sécurisée en raison de nombres aléatoires configurés de sorte que des clés pour chiffrer les données soient générées différemment pour chaque dispositif; et un processus de récupération de clé étant très rapide lorsque la clé est récupérée par l'opération modulo.

본 발명은 다수의 테이블이 갖는 모든 데이터의 합을 테이블 수로 mod하여 나온 수치에 해당하는 테이블을 추출한 후 추출된 테이블의 데이터 총합을 테이블 크기로 mod한 수치를 위치값과 키로 설정하고 같은 방법으로 위치값과 키를 키 길이 만큼 반복하여 생성된 키를 데이터와 결합하여 암호화하고 서명한 후 저장하는 데이터를 안전하게 보호하는 암호화 키 생성 모듈에 관한 것이다. 이에 따른, 본 발명은 데이터를 암호화하여 안전하게 저장하고 외부 노출로부터 안전한 효과가 있고 데이터를 암호화하는 키가 장치마다 다르게 생성된 난수로 인하여 데이터가 안전하게 보호되는 효과가 있으며 mod로 키를 찾음에 따라 키 찾는 과정이 매우 빠른 효과가 있다.
