Modify Key Command (encrypted)

Introduction/Additional information: 

This ASM implements the Project 25 OTAR Modify Key Command message.

Usage Notes

  • This message is sent from the Key Management Facility to the Mobile Radio (MR) to modify one or more keys in the keyset.
  • This message is broadcast as a non-addressed message, to reduce the message size, and to avoid issues from a relocated RSI to a different MMSI.
  • The “Number of Keys” field is set at two per message, in order to reduce and fix message size within AIS slot count limits.
