PROCEDIMENTO PER L'ARCHIVIAZIONE DI DATI DIGITALI IN MODALITA' CIFRATA

摘要

System for secure storage of data (DAT1), comprising a number N≥=4 of devices (100) for secure data storage, connected in a network, wherein an asymmetric cryptography decryption key (AD-K) generated by a device (100) is not present in the mass memory of the said device and is stored subdivided into M decryption key parts (AD-K1,AD-K2,AD-KM), with 2MN, each stored on at least one of the N-1 safe storage devices of the system (S), different from the device (100) which generated the asymmetric cryptography decryption key (AD-K), and wherein reconstruction data (S-MAP) able to allow the reconstruction of the asymmetric cryptography decryption key (AD-K) by the device (100) which generated it, from said M decryption key parts, is stored in at least one file saved in a part of the mass memory of the said device (100), encrypted by the operating system by means of said encryption key stored in the storage chip (170).
