    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 pseudorandom number generator includes a unit for providing a number of 2n sequences of numbers, n being greater than or equal to 2. The sequences of numbers are combined by a unit such that at first all the sequences of numbers are combined with one another in an intermediate processing stage to obtain an intermediate processing sequence, and that subsequently a subgroup of k sequences of numbers is combined with the intermediate processing sequence in a final processing stage to obtain the output sequence.

    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.
