Method for substitution of cryptogtaphic data

摘要

The second data processing unit (3) monitors fulfillment of the first exchange criterion presently associated with the first cryptography data and/or the first data processing unit (2, 6.1, 6.2). Once this criterion has been fulfilled, the second data processing unit (3) initiates the first exchange step (9.6). The first exchange criterion is assigned by the second data processor. The first exchange criterion is fulfilled before the current expiry criterion. The first expiry criterion and/or the first exchange criterion are functions of time. An independent claim is included for corresponding equipment.
