!n a method for exchange of first cryptography data (such as a cryptographic key or a cryptographic certificate) associated with a first data processing device, the current cryptography data are stored in a memory of the first data processing device, with which a current expiration criterion is associated. The stored cryptography data are exchanged for new cryptography data in an exchange step; wherein a communication with a remote second data processing device ensues and the exchange step is implemented at the latest upon fulfillment of the current exchange criterion. The fulfillment of the exchange criterion associated with the current cryptography data and/or the data processing device is monitored in a second data processing device and the second data processing device initiates the exchange step upon fulfillment of the exchange criterion.
