Data communication and handshake process

An authentication handshake between participants starts after participant discovery. If a reader and a writer are created during that period, their match is delayed until after the handshake succeeds.

Warning

During the handshake process, volatile data is lost (as if there is no reader).

After publication match, the encryption / decryption keys are exchanged between the reader and writer. Best-effort data that is sent during this exchange is lost. Reliable data is resent.
