Abstract: A transponder located for example in a contactless smart card receives energy via an antenna (L2) from a high-frequency alternating field. A voltage (Udd) formed with a rectifier (12) is fed as a control quantity to a clock generator (14) with a clock frequency adjusting device. At high field strength on the antenna, the voltage (Udd) is adjusted downwards by increasing the clock frequency for a digital circuit (10). If no further increase of clock frequency of the clock signal (CLK) is possible, a charge pump (16) is connected for an EPROM (18) in order to increase the writing speed thereof. Optionally, a conventional shunt regulator can be connected as well. An interface circuit (20) is not affected by the adjusted clock frequency, but works at fixed frequency during communication with a reader.

Abstract: The invention relates to a security element, preferably for documents of value, which at least has one area with a diffraction structure, which under specific viewing conditions reconstructs a diffractive image.

Essential is that the information represented by the subareas is recognizable mainly only under the viewing conditions, under which the diffractive image can be perceived.

Abstract: A method and apparatus for storing and retrieving a number of PIN codes for protected-access devices, in particular smart cards and magnetic stripe cards, involves storage of the individual PIN codes together with a unique feature of the associated protected-access device in a special apparatus, in particular a pocket card reader. The data stored in the pocket card reader can be accessed by a freely selected access code. By entry of the access code and the unique feature into the pocket card reader, the PIN number associated with the unique feature is found and indicated on a display for a short time. The unique feature may be a serial number that is inputted into the pocket card reader via a keyboard or automatically determined and used by the pocket card reader. The stored unique features and particular associated individual PIN codes may be encoded by means of the access code before they are stored. The access code remains stored as long as it is required for encoding or decoding.

Abstract: The invention relates to a method for authenticating a smart card (SIM) in a messaging network, preferably a GSM network, wherein an optionally secret algorithm and a secret key are stored in a smart card (SIM), whereby for authentication the network or a network component first transfers a random number to the smart card, a response signal is generated in the smart card by means of the algorithm, the random number and the secret key, said signal being transmitted to the network or network component in order to check the authenticity of the card there. According to the invention both the secret key and the random number transferred by the network are split into at least two parts to form the authentication message, one part of the transferred random number and one or more parts of the secret key being encrypted by means of a one- or multistep, preferably symmetrical calculation algorithm. To output an authentication response, a selectable part of the encryption result is transferred to the network.
