  • Apparatus for verifying and for generating an encrypted token and methods for same
    Patent number: 9043606
    Abstract: Embodiments show an apparatus for verifying a validity of an encrypted token associated to a product, wherein the apparatus has a decryptor for decrypting an encrypted token using a decryption key to obtain a decrypted token having information bits related to the product and structure bits. The apparatus further has an evaluator for evaluating whether the structure bits fulfill a predetermined condition, wherein the encrypted token is verified to be valid when the predetermined condition is fulfilled or is not verified to be valid when the predetermined condition is not fulfilled. Further embodiments show an apparatus for generating an encrypted token associated to a product, wherein the apparatus has a plain token generator and an encryptor for encrypting the plain token using an encryption key to obtain an encrypted token.
