The invention relates, inter alia, to a method for access control, performed by an access control apparatus (4). The method comprises obtaining access authorisation information (B, V) that is communicated to the access control apparatus (4) and that comprises at least one or more access authorisation parameters (B) and first check information (V); using at least the communicated access authorisation parameters (B), the communicated first check information (V) and a second key (S, ST) from a symmetric or asymmetric key pair, to perform a first check on whether the communicated first check information (V) has been produced by performing cryptographic operations by means of access authorisation parameters (B) corresponding to the communicated access authorisation parameters (B) using at leastone first key (S, ST) from the key pair, wherein the second key is stored in the access control apparatus (4).
