Problems solved by technology

However, the installation of the web server entails that different subsystems have to be configured and for this also require, for example, passwords and shared secrets.
If the configuration data is stored in the public part of the smart card, there is a risk that sensitive data will be read out and leaked if the card is lost, for example in a shipping path or in a customer environment
[0009] On the other hand, the problem arises that a product or system must be (pre)configured once, so that authentication against a smart card is possible

Embodiment Construction

[0037] In FIG. 1 a can be seen configuration data, shown simplified as data blocks, which were obfuscated according to the invention in a first step S1 .

[0038] According to this embodiment this is done based on the encryption key and the initialization vector. This is illustrated schematically by feeding the data as well as the key data and the vector data to the obfuscation process.

[0039] As a result, this process provides obfuscated configuration data. These data are deposited on the smart card in a second step S2, wherein these data are stored in the common memory of the smart card.

[0040] In this case, a second stage of obfuscation can be implemented in a second step S2 , which consists in breaking down the structure of the obfuscated data and storing them in the memory in a different structure than the original structure.

[0041] Furthermore, this second level may alternatively or additionally consist in adding further data to the obfuscated data, which do not ...

Abstract

The invention relates to a method for configuring electronic devices, particularly terminals, wherein during configuration at least parts of first configuration data on a chip card are fed to an electronic device, wherein the configuration data are stored on the chip card as second configuration data such that the stored data are the result of an obfuscation following at least one first algorithm. Furthermore, at least parts of the first algorithm can be derived by the electronic device. The stored second configuration data are subjected to a de-obfuscation by the device such that, having knowledge of the first algorithm, they can be reconstructed as first configuration data and the configuration of the terminal can be based thereon. The invention further relates to an arrangement having means for carrying out the method.

Description

technical field [0001] The invention relates to a method for configuring an electronic device, in particular a terminal, in accordance with the preamble of claim 1 and a device for configuring an electronic device, in particular a terminal, in accordance with the preamble of claim 10 . Background technique [0002] The use of plastic cards with integrated chips, also known as "smart cards", is generally known. Generally, these cards offer the owner the possibility of entering areas or accessing data which are only open to a limited circle, especially only to specific persons. Therefore, these cards have data that are necessary for this function and are therefore considered sensitive or secret data. [0003] Such chip cards generally for this reason contain a private data area which can only be accessed after a successful authentication - such as entering a "Personal Identification Number" (PIN) or biometric authentication - as well as a public area which can be accessed wit...
