摘要:
An identification system comprises at least one user medium (2), which is equipped to store a derived key and authenticate itself using the same with respect to a write and/or read device. Furthermore, at least one key dispensing medium (1, 71) is present, which comprises a monolithic first integrated circuit having storage means and processor means, wherein the first integrated circuit is equipped to store a source key and derive therefrom the derived key and to pass it on for storage in the user medium, wherein the user medium (2) is enabled neither directly nor by way of aids to read the source key from the key dispensing medium and/or the user medium is not enabled to calculate a derived key.
摘要:
An identification system is described that has: a plurality of user media (1), each of which has an integrated circuit (2) having memory means and an identification code (8) stored in the memory means; at least one reading device; wherein the reading device (41) is capable of contactlessly reading data for an authentication process from the integrated circuit (2) via radio waves; and wherein the identification system additionally has a user management device (31) and is capable of initiating or not initiating a process on the basis of whether the read user medium is recorded as authorised in the user management device. The system is distinguished in that each user medium additionally has an optically readable code (7) that contains an identification information item individually identifying the user medium in question, wherein the identification system is capable of recording a user medium recognised via the optically readable code in the user management device.
