I am working on an seminar paper regarding key exchange protocols. Of course my first choice of protocol was DH. Second, I choose Otway Rees protocol since I found it very interesting that there is not much literature existing.
So I did a little bit of research and have some basic knowledge regarding OR-protocol. I thing I somehow couldn't find were applications / use cases of Utway-Rees.
In literature they are talking about that its used for parties to agree on a secret key using TTP in unsafe networks and that its a common thing for VPNs. But one thing I am still missing is: where is implemented? Does it have some applications in TLS/SSL, or IPSec?
