Definitions

  • Private telecommunications systems (Private Branch Exchanges, PBX) today offer a wide range of features that can normally only be used by end devices that are directly connected to the PBX. Access to these features from outside, ie via the public network, is often not possible or blocked.
  • this DISA functionality not only offers advantages, but it also entails the risk of unauthorized use, which can result in high damage.
  • the present invention is therefore based on the object of specifying technical means which enable external access to protected performance features of private telecommunications systems (for example via the public network) while largely respecting the legitimate security interests of the operator of such private telecommunications systems.
  • This object is achieved by a device for performing user authentication with the aid of acoustic signals in connection with a telephone terminal with features according to claim 1.
  • This device comprises means for activating the device by a user, means for generating acoustic signals suitable for user authentication after activation and means for outputting acoustic signals in a suitable for transmission by a telephone terminal Wise.
  • the present invention is not restricted to applications in connection with private telephone systems, but rather that the present invention is generally used to carry out user authentication using acoustic signals in connection with a telephone end ⁇ device can be used. Any device that can receive commands in the form of acoustic signals via telephone lines is a possible field of application of the present invention.
  • the invention in this application is essentially to be described using the example of private telecommunications systems be, especially since it is riding to the expert no problems be ⁇ to run from this example another application of the invention.
  • the invention described here provides a separate small terminal (the "SecureDialer") for access control to a PBX, which enables external access to the PBX.
  • the SecureDialer is constructed like an auto dialer - that is, a device for generating acoustic signals for carrying out a dialing process in private or public telecommunications networks - which can be held against the mouthpiece of a telephone handset and which is used for automatic dialing enables phone numbers in the DTMF procedure via a built-in loudspeaker.
  • the SecureDialer additionally contains a data storage unit, preferably also a data processing unit, e.g. a crypto chip for encrypting information and possibly (depending on the authentication method used) an additional microphone.
  • Suitable authentication algorithms are known in large numbers to the person skilled in the art from the extensive specialist literature.
  • the publication "Information technology - Security techniques - Entity authentication - Part 2: Mechanisms using Symmetrie eneipherment algorithms" of the international standard ISO / IEC 9798-2: 1994 (E) is given here as an example, but not by way of limitation can serve the person skilled in the art as a possible source of information.
  • a remote station an authentication server, is required in the PBX to enable secure access to the PBX.
  • Access to the PBX is as follows: authentication is carried out between the external caller and the authentication server. To do this, the caller must first dial the number of the authentication server from any telephone. This can be done using both pulse and tone dialing. Depending on whether a (a) one-way or (b) two-way authentication method (see e.g. ISO / IEC 9798-2) is used, the further connection establishment preferably proceeds as follows:
  • the SecureDialer sends encrypted information (Token AB, see figure (2) in Appendix 2) in the DTMF process, which is decrypted and checked by the authentication server. If the token AB is correct, the calling subscriber is allowed to access the PBX features. He can now carry out the desired actions (e.g. dialing a phone number).
  • Token AB see figure (2) in Appendix 2
  • the authentication server After the authentication server has been selected, it sends a random number RB (see figure (3) in Appendix 2) to the SecureDialer via DTMF.
  • the SecureDialer which in this variant must have a microphone, calculates a value from RB, encrypts it to token AB and sends it to the authentication server. This decrypts and checks the token. If the token AB is correct, the calling subscriber is admitted for access to the PBX service features. He can now carry out the desired actions (e.g. dialing a phone number).
