The system which has the related device, and the aforementioned device which execute the safe deposition method of the digital data, the restoration method and these methods of the digital data which it is related
The method involves encrypting data (DATA) with a transfer key (RAND) by a depositor using a symmetric encrypting method e.g. data encryption standard method, and encrypting the transfer key with a public key (pkB)of a trusted third party by the depositor using an asymmetric encrypting method e.g. rivest shamir adelman method. The encrypted data and the encrypted transfer key are deposited on a storage support. The transfer key is generated by the depositor in a random manner before encrypting the data with the transfer key. Independent claims are also included for the following: (1) a method of recovering data (2) a device for securing data (3) a device for recovering data.
