Abstract: The invention refers to a method for accessing an passenger transportation device control means comprising several separated printed circuit boards (PCB), whereby each of these PCBs comprises a unique identifier (ID), and in which method the passenger transportation device control means comprise a matching table which is used by the passenger transportation device control means to perform a matching test to check the identifier of at least two of the PCBs and to put the passenger transportation device control means into normal operation only if their IDs match the IDs of the matching table. A service technician connects via a key to the passenger transportation device control means, which key enables the service technician to set the passenger transportation device control means into a fault finding mode, in which fault finding mode the passenger transportation device control means are initiated to skip the matching test before getting into operation, whereby the fault finding mode is terminated at the latest when the service technician terminates the key-based connection with the passenger transportation device control means.

Abstract: The invention allows verification of authenticity of a maintenance means connectable to a controller of a passenger transportation/access device of a building. A digitally signed license key including a public asymmetric cryptography key of the maintenance means and optionally a one-way hash of a unique identifier of the maintenance means is used for this verification. Furthermore, an asymmetric cryptography key pair of the maintenance means and a symmetric cryptography key created by the controller are utilized in this verification.

Abstract: The invention allows checking the validity of a license of a maintenance unit for accessing a controller of a passenger transportation/access device of a building, without a need for an online connection to a service center or the like. An expiration time of the license is read from an encrypted license file stored in the maintenance unit in response to detecting the maintenance unit being connected to the controller. A manufacturing time and a current usage time of the controller, both stored in a secure memory of the controller, are read. A total of the manufacturing time and the current usage time of the controller are compared to the expiration time of the license. In response to the total not exceeding the expiration time, the license is determined to be valid.
