METHOD AND SYSTEM FOR SECURE INFORMATION STORAGE IN FILE-BASED DATA WAREHOUSES

摘要

The present method increases the security of secure information storage in file-based data warehouses, wherein at least one public key of at least one user is obtained, and at least one file is obtained on at least one client. At least one key is generated for encrypting the at least one file that is stored in a file-based data warehouse; the at least one file is encrypted using the at least one key previously produced obtained for file encryption. The at least one key, by means of which the at least one file is encrypted, is encrypted using the public keys of users who are granted access to the at least one file. The at least one key that was encrypted in the previous step is saved in an encryption key base, and the at least one encrypted file is saved in a file-based data warehouse.
