Definitions

  • the invention relates to arrangements and methods for the use of services offered on the Internet or in other networks which make high security requirements.
  • Devices with chip card units are e.g. B. mobile phones, which are used essentially for voice transmission in mobile networks.
  • the so-called SIM module or the integrated chip card integrated in the mobile radio telephone serves for the authentication of the mobile radio telephone as a device authorized for the mobile radio and contains keys for the encryption of the transmitted voice information or for the decryption of the received voice information.
  • Another type of device with a chip card unit is e.g. Remote controls for television sets in which the chip card serves as proof of authorization and possibly also as a means of payment for the reception of chargeable television programs.
  • Computers such as personal computers or laptops, which have a landline or mobile network connection, are able to use Internet applications, for example using the http protocol.
  • chip cards are used which control the respective transactions via a chip card reader connected to the computer.
  • the connection to a mobile radio network can also be established via a cellular telephone equipped with a data connection - see, for example, "PC Professionell", March 1994, pages 253-260 or "Cash Flow", 2/95, pages 140, 141.
  • Possible applications of a computer in connection with a chip card are e.g. Authentication, digital signature generation, credit / debit card applications, electronic wallet.
  • a particularly high level of security can be achieved by asymmetrical cryptographic methods, in which the private key is stored in a manner that cannot be read out in the chip card and corresponding cryptographic methods can not be manipulated in the chip card.
  • Chip card modules for such applications are available on the market today, e.g. the SLE 44CR80S block from Siemens AG.
  • the object of the invention is to extend the field of application of the devices with a chip card unit so that secure transactions are possible in connection with a computer.
  • the device is expanded in such a way that it can also be used as a card terminal for a computer.
  • protected services available on the computer can be used.
  • the use of such an extended device in accordance with claim 2 in connection with a coupled computer, which is connected in a known manner to a communication network enables personal or public network services, for example via the Internet, to be used which are high in security Make requirements without the computers having to have chip card readers.
  • the advantage for mobile radio telephone holders is that they can use the network services from any standard computer, regardless of their location.
  • Developments of the invention relate to methods for operating such a device combination. These include the ready operation of the device serving as a card terminal, which, in addition to the handling of network services in the usual way, also enables encryption or decryption in a manner known per se.
  • control words via an existing microphone as proof of authorization, which are then digitized and forwarded to a control entity in the communication network and compared with a reference pattern.
  • identity of a user can also be verified on the basis of a personal biometric feature, which meets increased security requirements.
  • data and / or control information can also be transmitted from the computer via the connection interface to the memory in the device and stored there. This makes it possible to change or save data on the chip card.
  • These data can be, for example, keys for encryption or decryption or an amount of money for a cash card.
  • the latter for example in connection with a mobile radio telephone as a device, opens up the possibility of a card telephone, in that incoming fee impulses result in the corresponding amount of money being debited when operating as a telephone.

However, as shown in FIG. 2, the mobile radio applications for GSM / DCS 141 and the various Internet / network applications 142, 143, 14x can also be stored on a chip card with their different keys.
