Issue 5644: move checksums to application level                                                                                                                                                                     (smart-transducers-ftf)

Nature: Uncategorized Issue
Severity: 
Summary: It is proposed that the protocol provides checksums for parts of the MP rounds.
Then the application has to check a flag if the checksum has been correct and
react accordingly. Since the calculation of the checksum (some exclusive or
operations) is not significantly more effort than checking the flag the checksum
calculation should be moved to the application layer.
Resolution: Accept changes as proposed.
Revised Text: Revised Text:
Section 2.3.4 “Multi-Partner (MP) Round”
4. Type of protection of the data-frame (none, four-bit or eight-bit
checksum).
Section 2.3.7 “Data Security”
3. Each frame of an MP round can be protected by a four-bit or eight-bit
checksum (coded in the RODL).
4. When designing MP rounds, protected data bytes can be used if
required by the application scenario.
