FIELD: data storage devices.
SUBSTANCE: invention relates to data storage devices in which encryption is used. Task is to provide additional protection of data from external influences during their storage. Device comprises a storage device, encryption and decryption key generators, an encoder, a decoder, a control device, a slot programmer, wherein the first output of which is connected to the input of the encryption key generator, the second output of the programmer slot is connected to the input of the control device, the third output of the programmer slot is connected to the input of the decryption key generator, at the same time the encoder generates X° signals for each slot. Device can be built on logic elements and on programmable logic integrated circuits.
EFFECT: high security of stored data due to synchronized variation of encryption and decryption keys in a wide range, intended for limited time intervals (slot), as a result, multiple re-encryption is realized.
