DDSSEC11 — Non-Recoverable Communication After Authentication Session Terminated

After two participants are mutually authenticated and authorized, each participant's session with the remote participant (certificate, shared secret, challenge1, challenge2...) may be terminated/removed at a certain time for various reasons such as:

• Automatic termination: sessions should have a max lifetime to follow best security practices, to handle the fact that the remote participant's certificate may expire, be revoked, etc. and therefore no longer trusted (worst case scenario: the issuing CA (or any ancestor) cert expires/is revoked).
• Administrative termination: some administrator decides to force the session termination because of a security alert or for debugging purposes.

If the session is terminated on one side but not on the other, we end up in the same deadlock situation as in DDSSEC11-43 (scenario 1 and 2) except the root cause is not liveliness loss but simple automatic/administrative session termination.

This will be handled with DDSSEC11-43
