Abstract:
Provided is a method for access control, performed by an access control apparatus, including obtaining access authorisation information that is communicated to the access control apparatus having at least one access authorization parameter and first check information; using at least the communicated access authorisation parameters, the communicated first check information and a second key from a key pair, which second key is stored in the access control apparatus, to perform a first check on whether the communicated first check information has been produced by performing cryptographic operations by means of access authorisation parameters corresponding to the communicated access authorisation parameters using at least one first key from the key pair, and deciding whether access can be granted, based on the first check delivers a positive result and it is established that at least one predefined set of the communicated access authorisation parameters respectively provides access authorisation.

Claim (Index 20):
An apparatus comprising at least one processor and at least one memory that includes program code, wherein the memory and the program code are configured to cause the apparatus with the at least one processor to perform and/or control:\n a communicating of access authorization information comprising at least one or more access authorization parameters and first check information to an access control apparatus in order to enable the latter to decide whether access is permitted to be granted on the basis of the communicated access authorization information, wherein necessary conditions for granting access are that a first checking, using at least the communicated access authorization parameters, the communicated first check information and a second key of a symmetrical or asymmetrical key pair, said second key being stored in the access control apparatus, whether the communicated first check information was generated by performing cryptographic operations on access authorization parameters corresponding to the communicated access authorization parameters using at least a first key of the key pair, yields a positive result and it is determined that at least one predefined set of the communicated access authorization parameters, in view of respective pieces of reference information present in the access control apparatus at least at the time of the first checking, respectively authorize for access; wherein the memory and the program code are further configured to cause the apparatus with the at least one processor to perform and/or control action group A or action group B as defined below: action group A:\n a communicating to the access control apparatus of information comprising at least one fourth key that is encrypted using at least the first key of the key pair and that can be used in an authentication of the access control apparatus vis-\u00e0-vis the access authorization proving apparatus, or in the checking of the authenticity and/or integrity of information communicated to the access control apparatus, in order to enable the latter to decrypt the encrypted fourth key using at least the second key of the key pair and to use said fourth key. \n action group B:\n a communicating to the access control apparatus of information comprising at least one combination\u2014encrypted using at least the first key of the key pair\u2014of a fourth key and an identifier for the access authorization information or for the access authorization proving apparatus, wherein the fourth key can be used in an authentication of the access control apparatus vis-\u00e0-vis the access authorization proving apparatus or in the checking of the authenticity and/or integrity of information communicated to the access control apparatus, in order to enable the latter to decrypt the encrypted combination using at least the second key of the key pair, in order to obtain the fourth key and the identifier, wherein the identifier further constitutes one of the access authorization parameters, and wherein it is determined in the access control apparatus that the identifier contained in the communicated access authorization information authorizes for access if the identifier contained in the communicated access authorization information corresponds to the identifier obtained by decrypting the encrypted combination, or if the identifier contained in the communicated access authorization information corresponds to the identifier obtained by decrypting the encrypted combination and the identifier is not contained in a rejection list stored in the access control apparatus.
