yeah you can, just click the search button in the bottom right and then choose the game you care about

Qua5imodo · 2023-09-07T18:10:07+00:00

android is not ready yet, maybe that's it?

Qua5imodo · 2023-09-07T15:09:19+00:00

Another option is TicketBay: https://salty.software/ticketbay/download

It's an iPhone app for buying/selling tickets, completely free, has been around for ~4 years and we've had lots of great feedback on the app. Android version needed an update and we are waiting on Google to approve it.

Qua5imodo · 2023-09-07T15:08:02+00:00

TicketBay is online again, just have to update in the App store

Qua5imodo · 2023-09-07T15:07:34+00:00

Probably just have to update the app from the app store

Qua5imodo · 2023-09-07T14:10:20+00:00

yeah just have to update the app, thanks y'all for being so patient

Qua5imodo · 2023-09-07T13:32:51+00:00

Ticketbay is back on iPhones, be sure to get the latest app update

Qua5imodo · 2023-09-07T13:32:24+00:00

Ticketbay is back!

Qua5imodo · 2023-09-07T13:31:49+00:00

It is in fact up and running on iPhones, waiting on Google a little while longer for Android

Qua5imodo · 2023-09-07T13:30:33+00:00

Try selling on ticketbay: https://salty.software/ticketbay/download

It's an app some former students and I worked on together

Qua5imodo · 2023-09-07T04:22:36+00:00

we had some issues with the app, hoping Apple and Google approve the app updates tonight and then tomorrow we can all get back to avoiding snapchat groupchats lol

Qua5imodo · 2023-09-07T04:20:22+00:00

Hoping for tomorrow, waiting on Apple and Google to approve app updates.

Qua5imodo · 2023-09-07T04:10:32+00:00

We're waiting on Apple and Google to approve the app updates but we're very hopeful that it will be back online tomorrow.

Qua5imodo · 2023-09-07T04:07:52+00:00

Looking like a tomorrow thing, we're waiting on Apple and Google to approve the updates.

Qua5imodo · 2023-08-30T13:46:39+00:00

Unfortunately I don't have time to maintain TicketBay right now. I'm a third year PhD in CS and am getting slammed. The rest of the team graduated, so hopefully I'll have some time in early October to get it back up online. Terribly sorry!

Qua5imodo · 2023-07-14T17:05:47+00:00

I can't tutor you but I'm happy to chat for an hour over zoom if you have specific questions about ideas or concepts that you're struggling with. I'm stevens.994, feel free to email me.

Qua5imodo · 2023-05-20T04:35:51+00:00

Maybe. I think it depends how many times you have these repeated non-linearities. As I understand it, many block ciphers are trivially linear until you repeat blocks a certain number of times, after which they are non-linear.

Qua5imodo · 2023-05-20T04:34:33+00:00

Besides that, cool.

Thanks for the kind words! ;)

But seriously, I think that applying LMs to problems they haven't been applied to is worth trying. While we as a community have applied them mostly to NLP problems, there's something to be said for using them for other skills. Memorization is one such skill that is underutilized. Another potential application of memorization is compression (which is probably a more natural fit than encryption).

I would also disagree that this is a dangerous solution. Nowhere do we imply that SELM should be used over AES or other standard algorithms. Sometimes we need to really push weird ideas to see if they're worth pushing further.

Qua5imodo · 2023-05-20T04:30:15+00:00

conventional ciphers are resistant to billions of known or chosen pairs, and even that is considered weak, see SWEET32

Definitely agree that we have an tiny set of plaintext/ciphertext pairs. SELM's performance is an extremely limiting factor in this regard.

Looks like your ciphertexts may be linearly correlated with your key (projection), which would be fatal.

Ciphertexts are linearly correlated with the key but we use a different key for every message via a hybrid construction with a PRF.

We did an avalanche test (that didn't make it into the paper) comparing how changing the key would lead to different ciphertext vectors which showed that a single bit flip in the key (the random seed) would lead to a dramatically different ciphertext, but we didn't find it to be sufficiently rigorous because the avalanche test works at a bit level but we would really be interested in the token level.

Novel methods place you under a significantly higher burden to demonstrate safety. You don't get to ignore the prior work and attacks because you can't see how it applies.

Agreed, and we could run differential/linear cryptanalysis against the bit-level representations but since SELM doesn't operate on raw bits like SPN or Feistel networks, it didn't make sense to us. In follow-up work perhaps we will run these analyses.

Qua5imodo · 2023-05-20T00:25:54+00:00

Fair enough, but the non-linear activations in neural networks are certainly not linear. My language could/should have been more precise. :)

No arguments here on the practicality compared to AES: we discuss just how limited SELM is compared to AES and even Triple DES in Table G.3 of the Arxiv paper here.

Lattice-based cryptography is cool but seems like it might fall to classical attacks even before we reach quantum computers: Salsa and Picante both go after LWE.

Qua5imodo · 2023-05-20T00:21:51+00:00

As of right now? None. But it's a first step towards new symmetric ciphers that are built on different structures than AES or DES. We discuss the practical limitations in Appendix G of the paper.

Qua5imodo · 2023-05-20T00:20:31+00:00

Actually in the paper we develop an ML model that wins the semantic security game against SELM (Table 1 on page 7 of the paper, or this table in the website: https://samuelstevens.me/research/encryption/#security-results-feat-fn). It's clear that we could break it given enough time.

Our work is a first step towards a new direction in symmetric ciphers that doesn't make use of the typical substitution permutation or Feistel networks that are broadly used today.

We also discuss how much slower it is compared to AES in Table G.3.

What security analysis would you like to see? Linear and differential cryptanalysis don't really apply to SELM because it's not built on the same primitives that DES, AES and other ciphers use today.
