Parameter Dataset Key

The protecting part of a parameter dataset is interpreted as a common data block and therefore, if necessary, is protected with analogue methods also used by coding data. If using parameter datasets, you are able to use any random key as initial key (see common key information). In these cases the parameter dataset protection key takes the security function first associated with the initial key.

 

Technical that part of the parameter dataset possibly being coded has an internal structure, if encoded, not being distinguishable from an analogue parameter dataset part not encoded. In parameter datasets especially transformation tables are only present in form of their generation parameters, the transformation tables themselves have a much to concise structure. Therefore there is no possibility to decide whether a decoding trial of a protected parameter dataset results in an original parameter dataset that means it is successful or not. Also parameter datasets “wrong” decoded are usable. The programs cannot distinguish between “correct” and “wrong” decoded parameter datasets.

 

attention: If you save parameter datasets comprising intermediate states, please take into account that these datasets contains information concerning the security, even if it doesn’t include the final coding parameters totally. Such datasets for example can hold your initial key not included in the final coding parameters and not being deduced form these final parameters (!). For your safety you should encode such datasets with a “random” key before deletion.

 

In the selection area above the key input field you can decide to enter the key in a direct way (keyboard; direct key) or to read the key using a dataset (key dataset) or you can leave the parameter dataset unencoded respectively. The last of which means that by generating a parameter dataset this dataset is not encoded or is handled unencoded causing an error if it is marked encoded.

 

You can „encode“ a parameter dataset using an empty closing key (!), so the parameter dataset is marked “encoded” but in fact it isn’t. In this case you have to give an (empty) opening key too to use this parameter dataset with success.
