There exist other asymmetric encryption schemes; indeed there exists one that is basically non interactive Diffie Hellman key exchange, and DH was discovered before RSA was.
- Cyph0n 10y agoI was under the impression that RSA was first, but I guess I was wrong. DH is a key exchange algorithm, not a general public-key encryption algorithm. So, as far as I understand, TLS would work, but the others I listed would not.
- Ar-Curunir 10y agoRSA was the first PKE scheme, but El Gamal, another PKE, is essentially a small modification of DH. Elgamal was discovered in 1985; before encryption really hit the mainstream.
- Cyph0n 10y agoI see. I'm not too familiar with crypto, so thanks for explaining. I guess that the argument is now: would ElGamal have been invented had RSA never existed?
- Ar-Curunir 10y agoI think so; as I said it's essentially a small modification to DH.
