Monero uses elliptic curve for stealth address generation. And all the things i have read about stealth addresses mention elliptic curve. My question is are there other cryptosystems out there which could allow us to do the same ?
If so, do we also have PQC-Algorithms which would allow us to create stealth addresses ? Not that I'm concerned about Quantum Computers breaking privacy but I'm just curios.
I found a few related answers and comments regarding the importance of elliptic curve cryptography for stealth addresses, but none of them seem to answer this question directly.
ECDH with the private key of Bob gives the same result as ECDH with the private key of Alice and the public key of Bob. This is a neat feature of the Elliptic Curve cryptography algorithms (some other algorithms have this too, but there's more to come....
Also i found one related question what-is-elliptic-curve-cryptography-and-why-is-it-important-to-monero
But nowhere is mentioned if this is feature which only exists on Elliptic Curve Cryptography or if there are also other possiblities.
