    摘要: A device for protecting a data word against data corruption includes first and second determiners. The first determiner is configured to determine an error correction code cvA associated with a data word a so that cvA=aAT, with A being a generator matrix of a linear systematic base correction code, the columns of which enable performance of an x-bit error correction on replica of the data word a and the associated error correction code cvA. The second determiner is configured to determine an extended error correction code cvE so that (cvA|cvE)=aFT, with F being an extended generator matrix F = ( A E ) of an extended linear systematic correction code, the columns of which enable, using the extension error correction code cvE, performance of an y-bit error correction, with y>x, on a replica of the data word a and the associated error correction code cvA.

    摘要: Applying both an encryption and also a decryption algorithm, which is inverse to the encryption algorithm, as an encryption definition to thereby enable the use of an encryption unit and a decryption unit of an encryption/decryption device simultaneously, i.e. temporally overlapping, in an encryption process when a part of the data to be encrypted is supplied to the encryption unit while the other part is supplied to the decryption unit. The result is encrypted data or is a cipher text, respectively, whose parts are only “encrypted” in a different way. During decryption, it only has to be guaranteed by suitable regulations that those parts which were encrypted by the encrypted unit are again decrypted by the decryption unit, while the other parts which were “encrypted” by the decryption unit are “decrypted” by the encryption unit.
