Key-source Key-chain
The key-source key-chain is used to specify which keys to use.
You configure a list of keys with specific IDs and have different lifetimes so that keys are changed at
predetermined intervals automatically, without any disruption of service. Rollover enhances network security
by minimizing the problems that could result if an untrusted source obtained, deduced, or guessed the current
key.
RSVP handles rollover by using the following key ID types:
•
On TX, use the youngest eligible key ID.
•
On RX, use the key ID that is received in an integrity object.
