The roadwarriors <b>carol</b> and <b>dave</b> set up a connection to gateway <b>moon</b>.
|
|
At the outset the gateway authenticates itself to the clients by sending
|
|
an IKEv2 <b>RSA signature</b> accompanied by a certificate.
|
|
The roadwarrios then use the <i>Extensible Authentication Protocol</i>
|
|
in association with an <i>MD5</i> challenge and response protocol
|
|
(<b>EAP-MD5</b>) to authenticate against the gateway <b>moon</b> and includes
|
|
a <b>Postquantum Preshared Key (PPK)</b> that's also mixed into the
|
|
derived key material. The PPK_ID used by <b>dave</b> is unknown to <b>moon</b>
|
|
but since both peers don't enforce the use of a PPK they fall back to regular
|
|
authentication by use of the authentication data provided in the NO_PPK_AUTH
|
|
notify.
