Patent ID: 8880859

Claim:
A method for configuring an electronic device, wherein during configuration at least parts of configuration data on a chip card are fed to the electronic device, the method comprising: a) obfuscating first configuration data by encrypting the first configuration data in accordance with a first algorithm to transform the first configuration data into second configuration data having a first structure; b) further obfuscating the second configuration data by resolving the first structure of the second configuration data to save the second configuration data in a second structure that is different from the first structure; c) saving the second configuration data in the second structure in non-transitory storage memory of the chip card; d) subjecting the stored second configuration data to de-obfuscation to reverse the encryption of the second configuration data to transform the second configuration data into the first configuration data; and configuring the electronic device based on said first configuration data after the second configuration data is subjected to the de-obfuscation and is transformed into the first configuration data.
