Abstract:
1. Apparatus for generating an encrypted token associated to a product, the apparatus comprising: a plain token generator for generating a plain token, wherein the plain token generator is configured to generate a plain token comprising information bits related to the product; wherein the plain token generator is configured to generate a plain token comprising structure bits related to a predetermined condition for verifying a validity of the encrypted token; wherein the plain token generator is configured to generate structure bits, which fulfils a predetermined condition; an encryptor for encrypting the plain token using an encryption key to acquire an encrypted token; and wherein the plain token generator is configured to determine a higher number of information bits when a first subset of functions of the product comprising less, less expensive or less complicated functions to be usable, is generated and to determine a lower number of information bits when a second subset of functions of the product comprising more, more expensive or a more complicated functions to be usable, is generated.
