An authority for guaranteeing an article's quality and origin provides the article with devices that contain a first digital non-readable key/code, with which an initial value is encrypted for authenticating the article. The encrypted initial value is decoded to a final value with a second digital key/code issued by the authority for guaranteeing the article's quality and origin. Independent claims are also included for the following: (A) An article to be checked for authenticity via a radio frequency computer identification chip storing a non-readable cryptographic key; (B) and for a device for assigning second keys/codes to digital certificates.
