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.
摘要翻译： 将与加密算法相反的加密和解密算法应用为加密定义，从而能够在加密中同时使用加密/解密装置的加密单元和解密单元，即时间上重叠 当将一部分要被加密的数据提供给加密单元，而另一部分被提供给解密单元时，处理。 结果是分别是加密数据或密文，其部分仅以不同的方式“加密”。 在解密过程中，必须通过适当的规定来保证被加密单元加密的部分再次被解密单元解密，而由解密单元“加密”的其他部分由加密“解密” 单元。

摘要： An encryption unit and decryption unit located in an encryption/decryption device may be used both for encryption and decryption, without their effects canceling each other out when, between the decryption input of the decrypter and the encryption output of the encrypter. An encryption combiner maps the encryption result data block at the encryption output to a mapped encryption result data block according to an encryption combining mapping and is exemplarily used when encrypting. A decryption combiner maps the encryption result data block at the encryption output to an inversely mapped encryption result data block according to a decryption combining mapping which is inverse to the encryption combining mapping and is exemplarily used when decrypting.

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： By arranging a redundancy means and a control means upstream from an encryption means which encrypts and decrypts the data to be stored in an external memory, the integrity of data may be ensured when the generation of redundancy information is realized by the redundancy means, and when the generation of a syndrome bit vector indicating any alteration of the data is implemented by the control means. What is preferred is a control matrix constructed from idempotent, thinly populated, circulant square sub-matrices only. By arranging redundancy and control means upstream from the encryption/decryption means, what is achieved is that both errors in the encrypted data and errors of the non-encrypted data may be proven, provided that they have occurred in the data path between the redundancy/control means and the encryption/decryption means.
