Title (EN) METHOD AND SYSTEM FOR SECURE STORAGE OF DIGITAL DATA
(FR) PROCÉDÉ ET SYSTÈME DE STOCKAGE SÉCURISÉ DE DONNÉES NUMÉRIQUES
Abstract:
(EN) A method and system for secure storage of digital data offers enhanced resistance to threat actors (whether insiders or hackers) gaining unauthorised access to extract and manipulate data, and to brute force computational attacks. The method employs double randomised fragmentation of source data into a random number of fragments of random sizes, encryption of each fragment with a separate encryption key, storage of the encrypted fragments and keys and a catalogue of the mappings of locations and fragments to keys all in physically and logically separate locations in a secure storage estate (1). The method may be repeatedly applied to encrypted fragments, keys and catalogue in a cascade fragmentation process to add further levels of security.
(FR) Selon l'invention, un procédé et un système de stockage sécurisé de données numériques offrent une résistance améliorée à des acteurs de menace (qu'il soient des initiés ou des pirates) qui obtiennent un accès non autorisé pour extraire et manipuler des données, et aux attaques informatiques par force brute. Le procédé utilise une fragmentation aléatoire double de données sources en un nombre aléatoire de fragments de tailles aléatoires, le chiffrement de chaque fragment avec une clé de chiffrement séparée, le stockage des fragments chiffrés et des clés et d'un catalogue des mappages d'emplacements et de fragments avec les clés tous dans des emplacements séparés physiquement et logiquement dans un domaine de stockage sécurisé (1). Le procédé peut être appliqué de manière répétée à des fragments chiffrés, des clés et le catalogue dans un processus de fragmentation en cascade pour ajouter d'autres niveaux de sécurité.
