APPARATUS FOR ENCRYPTING DATA

摘要

An apparatus for encrypting data is provided. The apparatus is capable of symmetrically encrypting data and then encrypting the symmetrically encrypted data with the aid of a bit string. The bit string has a maximum entropy. Encryption of the symmetrically encrypted data is designed such that a section of the bit string is used for encryption and successive encryption operations are carried out with carrying sections of the bit string while the bit string remains unchanged.

1. An apparatus for encrypting data, the apparatus comprising:
a symmetrical encryption device, said symmetrical encryption device encrypting data and creating symmetrically encrypted data; an encryption device, said encryption device encrypting said symmetrically encrypted data with the aid of a bit string and creating twice encrypted data, wherein said bit string has a maximum entropy, said bit string is generated from a physical process, and only a section of said bit string is used for encrypting said symmetrically encrypted data, and wherein successive encryption operations are carried out with varying sections of said bit string, wherein said bit string remains unchanged.
