The signing process is divided into the following sections:
-
Signer Authentication
-
Signature Information Selection
-
SAD Generation
-
Signing Key Activation
-
Signature Value Creation
The Signing process corresponds to the usage scenario (US6) Signing and the operation Signing assigned to the SAM.
There are basically two different approaches to commissioning remote signature. The both resulting processes differ when it comes to the SAD generation. Either the SAD ist generated via a locally installed SAK/OS or this is done via a remote SAK. Both processes are described below.
