Abstract: 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.

Abstract: The invention relates to a method for the measurement and/or determination of sensory disorders, in particular, related to neuropathies, whereby an air current (10) is directed at a measuring point (4) on the body of a living being, in particular a human, by means of a device (2), in order to influence the thermal sensitivity of the being at said measuring point (4), during a measuring process. The thermal sensitivity and/or a change in thermal sensitivity is correlated with a perceived temperature and, in order to determine the perceived temperature before and/or during the measurement process, at least one parameter from the environment and/or the being is recorded and analysed. The invention further relates to a device for the measurement and/or determination of sensory disorders, in particular, related to neuropathies.

Abstract: The invention relates to a method and a device for the generation of checkable forgery-proof documents with an externally supplied cryptographic module, whereby the checking of authenticity of the document is carried out without using key information belonging to the cryptographic module. According to the invention, the method and the device are characterised in that the cryptographic module is supplied with two types of data, even on supply from a communication partner which is cryptographically not trustworthy, which either remain in the cryptographic module or are attached to the document. The information remaining in the cryptographic module is used to secure the document information by means of a check value and the information transferred into the document serves to verify the securing of the document by the cryptographic module during a check of the authenticity of the document at a checkpoint.

Abstract: A method for authentication and identification uses different keys for the prover and the verifier, but on the other hand dispenses with the utilization of long number modulo arithmetic by the use of simple basic components such as, for example, arithmetic operations in finite bodies GF(2n). A private key is stored in the prover, so that the latter can receive, in encrypted form, data elements generated as random elements and can itself utilize them again as key for an authentication method of a data set to be transmitted. The verifier receives the authenticator thus formed and checks it. If the data set is generated by the verifier and transmitted to the prover, then this method can serve for the identification of the prover. The method is particularly advantageous in the area of smart cards, since there the required space in the hardware implementation can be considerably reduced.

Abstract: The invention is characterized in that the data processing unit detects the error and then sends a first coded message to a central data processing facility. The central data processing facility decodes the signal and evaluates information on the error contained in the first message. Depending on the result of said evaluation, the central data processing facility then generates and/or selects an error elimination routine. The central data processing facility issues a program instruction that can be executed by the data processing unit. The program instruction is then coded by the data processing facility and sent to the data processing element as part of a second message.
