What is the post-quantum cryptography alternative to Diffie-Hellman?
For authenticated/mutually authenticated key exchange, you can use that piece of TLS. TLS requires public key encryption and a key derivation function for the key exchange (plus a signature algorithm …

How does the wider cryptographic community view non-abelian group based cryptography?
In my experience, I never have found that cryptographers base their opinion of a cryptosystem on the properties of the underlying group. If its a braid group, abelian group, or finite field: that does …

Generalizing the conversion of Diffie-Hellman to El Gamal
The conversion of Diffie-Hellmen into Elgamal is assisted by a few factors that are not inherent to key exchange/agreement protocols in general, but a general conversion may be possible.
The DH $\rig …

Do Quantum Key Distribution and Physical Unclonable Functions combine, and how?
It seems difficult to combine the two. PUFs can provide authentication but they are based on the sender having first built up a small number of challenge/response pairs before handing the PUF over. So …

Is it possible to ensure security with zero pre-shared information?
No. Consider using encryption to protect against a passive adversary. In this case, encryption needs to hold from the sender to the receiver. The sender can verify that the message leaves them encrypt …

RSA-based authentication and key-agreement protocol
What you are looking for is authenticated key agreement with perfect forward secrecy based on certificates.
First, to address @Paulo's comment, TLS/SSL does provide this functionality with any of the …
