Fix packs for DataPower B2B Appliance version 7.0
Fix packs for DataPower Gateway version 7.1

APAR status

• Closed as program error.

Error description

• DataPower might not use the requested algorithm to calculate
  Message Disposition Notification Message Integrity Check (MDN
  MIC) for the inbound flow, which might result in MDN MIC
  mismatch error for external partner.
  

Local fix

Problem summary

• Affected are DataPower customers using B2BGateway as a receiver
  (inbound gateway) for unsigned message and sending back sync MDN
  with SHA2 signature.
  
  When the requested sign algorithm is SHA2 for MDN, DataPower
  will generate the MIC with only the payload, however, our
  partners were expecting the MIC to be generated with payload and
  part of the request header in this case.  With the fix,
  DataPower will now use the right way to generate the MIC.
  

Problem conclusion

• Fix is available in 7.0.0.5.
