发明名称 Method, system and securing means for data archiving with automatic encryption and decryption by fragmentation of keys
摘要 In the method for data archiving with automatic en- and decryption data (9, 10) are exchanged between a client station (1) and an archive station (4). A securing means (2) connected between the stations (1, 4) encrypts the plain data (9) which are transmitted towards the archive station (4) and decrypts the encrypted data (10) which are transmitted towards the client station (1). The encryption is carried out with at least two keys (6, 7). One of the two keys (6, 7) is swapped out by transmitting it to the archive station (4) and deleting it locally, i.e. in the securing means (2), after the encryption. If the securing station (2) is stolen, the encrypted data (10) on the archive station (4) can be accessed, however their decryption can be prevented in a simple, reliably and comprehensible manner by deleting the swapped out key (7) in the archive station (4).
