Calculation format for signature generation
Parameter-ID:
UHF-Manager:
OPC UA:
Webserver:
Defines the data areas of the data carrier that are included
in the calculation for generating and verifying the signature
(usually the EPC and the TID, possibly also part of the user
data area for data carriers with larger memory). The area
where the signature itself is stored (currently the first
64 bytes of the user data area) must not be included.
Meaning
The specification must be exactly the same for signature
generation and signature verification, otherwise the
signature cannot be recognized as valid.
Prefix for
The specifications are generated using the same system
ReadMul-
as for the formatted output, although it is not useful to
tipleTag-
specify format modifiers (X, x, or d).
DataFor-
Examples:
matted
12 bytes of the EPC and 12 bytes of the TID are to be
included:
Calculation format: "%E[0.12]%T[0.12]"
12 bytes of the EPC and 12 bytes of the TID and 16 bytes
of the user data area starting at address 64 are to be
included:
Calculation format: "%E[0.12]%T[0.12]%U[64.16]"
