DDSSEC12 — Add explanation of how to use the secureWriterSet to support GROUP ordered access

Open Closed All
  • Key: DDSSEC12-68
  • Status: open  
  • Source: Real-Time Innovations ( Dr. Gerardo Pardo-Castellote, Ph.D.)
  • Summary:

    RTPS 2.4 added support for GROUP ordered access and coherent access. Part of this work added fields to the heartbeat submessage, one of which is a secureWriterSet.

    This field shall contain the 32-bit xxHash32 of all of the writer EntityIds that are sent via secure discovery.

    The use of this field should be mentioned somewhere in the security spec as the RTPS spec refers to the security specification to define the use of this field.

    A new inline QoS was also added: PID_SECURE_WRITER_GROUP_INFO. This inline QoS should also be added to the security spec.

    See the revised RTPS text here: DDSIRTP23-117
