DDSSEC_ — Multiple DataReaders per topic on secured Participant

  • Key: DDSSEC_-190
  • Status: open   Implementation work Blocked
  • Source: ZettaScale Technology ( Mr. Julien Enoch)
  • Summary:

    Looking at the datareader_crypto parameter description of the preprocess_secure_submsg operation:

    "If secure_submessage_category is DATAWRITER_SUBMESSAGE, the datareader_crypto shall be the DatareaderCryptoHandle returned by a previous call to register_local_datareader for the DataReader that is the destination of the RTPS Submessage."

    It seems that only a single DatareaderCryptoHandle can be returned. This implies that a secure DATAWRITER_SUBMESSAGE should be at destination of a single DataReader.

    How to deal with several DataReaders in a Participant matching the same DataWriter ? Most of the time, the submessage destination is ENTITY_UNKOWN. As a consequence a clarification is required.
