In addition to the supported cluster & per-node encryption keys for the
en/decryption of TIPC messages, we now introduce one option for user to
set a cluster key as 'master key', which is simply a symmetric key like
the former but has a longer life cycle. It has two purposes:
- Authentication of
We reduce the lasting time for a pending TX key to be active as well as
for a passive RX key to be freed which generally helps speed up the key
switching. It is not expected to be too fast but should not be too slow
either. Also the key handling logic is simplified that a pending RX key
will be
Rekeying is required for security since a key is less secure when using
for a long time. Also, key will be detached when its nonce value (or
seqno ...) is exhausted. We now make the rekeying process automatic and
configurable by user.
Basically, TIPC will at a specific interval generate a new key
With support from the master key option in the previous commit, it
becomes easy to make frequent updates/exchanges of session keys between
authenticated cluster nodes.
Basically, there are two situations where the key exchange will take in
place:
- When a new node joins the cluster (with the
This series adds some new features to TIPC encryption:
- Patch 1 ("tipc: optimize key switching time and logic") optimizes the
code and logic in preparation for the following commits.
- Patch 2 ("tipc: introduce encryption master key") introduces support
of 'master key' for authentication of new
