Abstract

Provided is a method for access control, performed by an access control apparatus, including obtaining access authorization 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 authorization 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 authorization parameters corresponding to the communicated access authorization 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 authorization parameters respectively provides access authorization.
