    • An access-controlled system includes a portable identification device and a control unit with which the encoded information on the identification device can be read. The control unit allows a user access to the system once the identity of the identification medium has been established. The portable identification device includes a signal generator device configured for generating a reproducible acoustic signal in a mechanical manner. The reproducible acoustic signal includes a clacking noise, a frequency spectrum of the clacking noise encoding information. The signal generator device includes a tongue, plate, and/or curved surface that folds upon an overcoming of an initial resistance, the folding generating the clacking noise. The tongue, plate, and/or curved surface springs back to an original position subsequent to being acted upon.
    • 访问控制系统包括便携式识别装置和可以读取识别装置上的编码信息的控制单元。 一旦建立了识别介质的身份,控制单元允许用户访问系统。 便携式识别装置包括被配置为以机械方式产生可再现的声信号的信号发生器装置。 可再现的声信号包括敲击噪声,起重噪声编码信息的频谱。 信号发生器装置包括在克服初始电阻时折叠的舌,板和/或曲面,折叠产生敲击噪声。 舌,板和/或曲面在作用之后弹回到原始位置。

    • A method for providing a time stamp by using a tamper-proof time signal via a telecommunications network includes the steps of: receiving, at a central system, a request from a network user for a time signal. The time signal is encrypted by the central system with at least one key. The encrypted time signal is transmitted to the network user via the telecommunications network. The network user is provided with the same at least one key. At the central system and the network user, the at least one key is synchronously generated.
    • 通过电信网络使用防篡改时间信号来提供时间标记的方法包括以下步骤:在中央系统处接收来自网络用户的时间信号的请求。 时间信号由中央系统用至少一个密钥加密。 加密的时间信号通过电信网络发送给网络用户。 网络用户具有相同的至少一个密钥。 在中央系统和网络用户处,同步生成至少一个密钥。
