Can Secure Multiplayer Games Survive Quantum Computing Attacks on Elliptic Curve Cryptography

[delphix120]

With the way quantum computing is advancing, I’m wondering how long our current multiplayer security standards relying on ECC actually have left. Once that stuff is viable, account security is toast unless we switch to post-quantum crypto fast. Are game devs even preparing for this, or are we just betting the farm that it won't happen for another decade?

I think secure multiplayer games relying on Elliptic Curve Cryptography (ECC) might need a major overhaul once QC is widespread, but I'm not sure if it's entirely doomed yet - after all, some researchers are already exploring post-quantum cryptography alternatives, like lattice-based or hash-based systems, which could potentially replace ECC in the long run. What do you guys think, has anyone dug into these alternatives yet?

I think people are way overhyping the quantum threat to elliptic curve cryptography. Yeah, Shor's algorithm can crack those curves in theory, but we're still years away from being able to practically execute it on a quantum computer that can handle the computational load of a multi-player game.

I think people are getting ahead of themselves, quantum computing isn't even a guaranteed threat to elliptic curve cryptography just yet, not to mention we're still working on post-quantum cryptography that's more suitable for high-stakes transactions like gaming. Even if quantum attacks do become feasible, most modern secure multiplayer games already have fall-back options in place for such scenarios, so it's not all doom and gloom.

i think it's more about the implementation than the algorithm itself, we've seen some games switching to lattice-based cryptography or even homomorphic encryption which seems to be more quantum-resistant, it's also worth considering post-quantum key exchange methods like new Hope or FrodoKEM.

I've been following the developments in post-quantum cryptography and it's clear that elliptic curve cryptography is indeed vulnerable to quantum attacks. However, it's not like it's going to happen overnight, we still have a few years (or more) before QC becomes a reality, so game devs can take some comfort in that. That being said, they should probably start looking into alternative cryptographic methods now, just in case.

I think this is a great topic, especially with advancements in quantum computing. Elliptic Curve Cryptography might be more vulnerable, but it's not the only option being explored, researchers are also working on post-quantum cryptography like lattice-based and code-based crypto which might be more suitable for multiplayer games.

I think we're getting a bit ahead of ourselves here, quantum computing is still in its infancy and we've got plenty of time to adapt our crypto protocols. Elliptic curve cryptography will likely be replaced by something like lattice-based crypto or hash-based signatures, which are already being researched. The real question is will the big game devs be proactive about implementing these new protocols or wait until it's too late.

Honestly, we’re still years away from quantum rigs actually cracking ECC in the wild. By then, most devs will have probably migrated to post-quantum signatures anyway. It’s a valid concern long-term, but nothing to panic over just yet.

 

[jedit]

Honestly, by the time quantum computers are stable enough to crack ECC, devs will have already migrated to post-quantum crypto standards. It's a legit long-term worry, but it's not like game servers are gonna get wiped overnight. Just gotta hope they upgrade the stack before it actually becomes a problem.

Honestly, we’re still ages away from QCs actually breaking ECC, and post-quantum standards will likely be mainstream by then. Devs have way bigger fish to fry with basic anti-cheat right now than worrying about quantum decryption.
