    摘要: A process and system for generating a pseudo-random number is presented. Input data having entropy is gathered in an Entropy Pool and transformed once by a cryptographic hash function. The transformed data forms the internal state of the pseudo-random number generator. The generator forms the output by applying a second cryptographic hash function to this internal state. Finally, the generator updates the internal state by inputting the current internal state and data from the Entropy Pool into a third cryptographic hash function. The output of the third hash function forms the new internal state of the pseudo-random number generator.

    摘要: A drive unit in particular for an actuating element of a motor vehicle, is described, which has a gear mechanism unit, a drive motor and a contacting unit, with the gear mechanism unit encompassing a first interface for a detachable attachment of the drive motor and a second interface for the detachable attachment of the contacting unit, and with the drive motor being energized by the contacting unit in the mounted condition. The interfaces of the gear mechanism unit are designed to energize the drive motor through the contacting unit, and a rotary sensor that can contact the contacting unit and can detect the rotation of a gear mechanism rotating element (for example 6) is provided. Such a drive unit is very flexible with regard to the applicable control- and/or regulating electronic system.
