The thing is, nobody will break it but the NSA. So it's secure to a certain extent. Their argument is that it is designed to fit well within hardware and it is fast. I agree, but it's non-sense. Linux people don't really have a choice from where they stand but you do, you can patch up your own kernel. If you can't, learn how. If you don't want to then don't complain about the world being unfair. It's a game and if you're willing to play, better be aware of the repercussions.

IoT faggots who want to telemetry you to death need to send a lot of totally non-invasive data about you to their servers and don't want you peeking, yet their boards are low power and shitty as to spy on you from your sneakers. AES is too heavy that, because it actually encrypts things. So they want a variable block and key algorithm that is more modern than the couple people have been using that feel like they were found written on the back of a napkin. The variability means the choice of rounds is extremely complicated (if you want it to meet some level of security) and is probably the most interesting piece. That the NSA dodged him on his attempts to get them to explain mean it's compromised.


 No.951519>>951537

Btw, the IoT guys only care that it works on their hardware, that it's a standard, and that it was an unmodified part of their stack, as their channel partners will require it. They don't care at all if it's actually secure. They exert force on Linux devs to get shit like this mainlined to satisfy their requirements.

To answer your question, you have to look up who benefits from IoT spread: The chip makers. They manufacture billions of chips. Intel is the largest chip designer and manufacturer so far and if you look at their product range you'll undrstand. Intel is also one of the top contributers to Linux and other open source products. Intel is also closely related to all US agencies given that it ships crypto in its chips and they are sold almost everywhere on this planet. Keep in mind that all major tech companies play a behind the veil game where they throw technical flowers into each other to maintain their supremacy in a market niche.

Also, IoT has been introduced as "fun" and educational by other entities. Look around YouTube and you'll see how many tutorial videos for connected this, WiFi that are there and the childish pseudo-pedagogical packaging.

Honestly, for the aware mind it's good, you can hack the shit out of it and you get to sharpen your mind with some technical skills and learn how to make a phone out of parts, a care-free green house, ... whatever you wish.

On another side, ready-made products are to be approached with caution. Capitalism isn't serving the Human, it is serving the self proclaimed Masters. They will fall only when the Human becomes responsible and stops relying too much on other people's work while being a total ignorant.

If it requires certain initial values or constants, you can have solid math and still have a backdoor.

That is where the concept of "nothing up my sleeve number" originates from.

Or alternatively, it would take maybe 10 years of concertrated effort to break it, time that the NSA has already spent, since they lied about starting on it in 2011, or just build off of some earlier project.

That gives them until about 2023 until the goyim know, plenty of time for it to find it's may into billions of unupgradable devices.

It's not about math. Equations are math, processes are math. Constant values are data. Data isn't math it's raw number values.

When you get an algorithm with unexplained pulled-out-from-a-hat constants, you should be cautious. DES had P-Box and S-Box values chosen in a way that any key could at least be partially, if not totally, extracted. And it was broken when the public cyptographers started to get more compute power and understanding only reserved to the happy few who dwelt in the den of the three horned deamon (xD).

Speck uses same constants for number of rounds and ... without any single proof that it is the most secure value for that constant. At least, that's the argument presented. Also, powder all of this with typical NSAssholeness and things get stinky.

A proven backdoor means proof that the constant was derived in such a way that they own a master key. There is no proof of that. But they couldn't show how they chose those values which is enough smoke to assume fire. They're making the same refusals with spark.

There are lots of dangerous constants in crypto and today are usually chosen via formulas in such a way as to prove that you've limited the amount of control you had over the value. E.g. the 8192 bit SRP verifier is defined as "2^8192 - 2^8128 - 1 + 2^64 * { [2^8062 pi] + 4743158 }" not because there's some special magic to that formula (there's some minor magic) but because it produces a 8192 bit value that can be easily shown to be prime and shows it's not some transformation of a secret 8192 bit master key.

Oh? AES (Rijndael) was not made by NSA, but by two European academics. RSA was not made by NSA. Nobody (smart/informed/free) uses the backdoored elliptic curve NSA pushed. They (or GCHQ, I forget) claimed to have discovered asymmetric cryptography first, but they didn't share it publicly and it was rediscovered independently by non-NSA academics. It's true that the NSA designed the SHA-2 suite of hash algorithms, but their design was based on the work of Ralph Markle and Ivan Damgård, one of whom is European, and neither of whom worked for NSA, as far as I can tell. It's true that the SHA-2 suite is important and widely used, though it is going to be phased out by SHA-3 (Keccak, which was not designed by NSA) in the future. In terms of protocols, NSA invented none of TLS, OpenPGP, Axolotl, etc. So, unless there's some significant contribution that I'm missing, your assertion that NSA is responsible for half the crypto we use today is, at best, a significant exaggeration, but probably just total bullshit.

>Their job is making and breaking security Not breaking it.

It's true that that is nominally NSA's mission, and there are historical examples of NSA being "good guys", like when they strengthened DES against differential cryptanalysis, which they knew about, but most people didn't at the time. However, that time seems to be over, and NSA now seems far more interested in its SIGINT mission than its COMSEC mission.

> Update: I am not sure if it was the impact of our story here but it looks like Speck will be removed from Linux Kernel. Apparently, Google has now dropped the idea of using Speck for Android Go and since no one is going to use this algorithm, there is no point in keeping it in Kernel.

That's not how things work. Once something's in the kernel, anyone might use it for anything. Putting code that is extremely likely to be backdoored in the kernel raises its profile, makes it usable by contractors with a "no third party code" requirement, and is taken as a seal of approval. There's a philosophical argument as to whether landmines bad code should be made available like that and also surely a very large amount of shilling going on as this is likely a many million shekel project of the NSA's.

That's literally a LARP presentation. Watch the first 2 minutes.

If you think they'd only spend 5 figures researching, testing, creating, getting approvals for, and promoting a complex new algorithm through multiple national standardization processes you're out of your mind. "5 figures" would be all this being done by one man in one year.

Dual EC DRBG has kleptographic backdoors. In it's proper application, a kleptographically backdoored encryption algorithm cannot be distinguished from a legitimate one, expect for the attacker who implemented it in the first place.

https://en.wikipedia.org/wiki/Kleptographic

>A kleptographic attack is an attack which uses asymmetric cryptography to implement a cryptographic backdoor. For example, one such attack could be to subtly modify how the public and private key pairs are generated by the cryptosystem so that the private key could be derived from the public key using the attacker's private key. In a well-designed attack, the outputs of the infected cryptosystem would be computationally indistinguishable from the outputs of the corresponding uninfected cryptosystem. If the infected cryptosystem is a black-box implementation such as a hardware security module, a smartcard, or a Trusted Platform Module, a successful attack could go completely unnoticed.

>A reverse engineer might be able to uncover a backdoor inserted by an attacker, and when it is a symmetric backdoor, even use it himself. However, by definition a kleptographic backdoor is asymmetric and the reverse-engineer cannot use it. A kleptographic attack (asymmetric backdoor) requires a private key known only to the attacker in order to use the backdoor. In this case, even if the reverse engineer was well-funded and gained complete knowledge of the backdoor, it would remain useless for him to extract the plaintext without the attacker's private key.

Does anyone here use Kuznyechik and Camellia daily? They are made by Russians and Japanese respectively and I think former doesn't have any backdoors that can be exploited by NSA. I can't confidently say the same for KGB but anyway it's secure enough to be used in western countries imho.

Grover's algorithm already reduces AES-n by (2^n)^(1/2) so AES-128 can be broken with 2^64 steps, rendering it unusable within the next decade or so. AES-256 on the other hand, should be secure for the foreseeable future.

That seems way to optimistic. Can you explain your reasoning about this figure. Make sure to remember that the quantum computers we have now are different than theoretical ones because we have a lot of error to deal with.

OS choice doesn't even matter anymore because of hardware backdoors that are added for IT "enterprise" solutions. AES probably also has a backdoor but even if it doesn't all modern processors which use code that has AES-NI in it would be perfect for a side-processor inside the CPU to remember and or call home saying somebody is using AES and here are some values.

NSA led Feminist Social Justice has completely ruined the decision making in a lot of the community.

It matters a little, because Windows 10 outright spys on everything you do. Pretty much any Linux distro is better than that.

Of course, the hardware isn't safe, but that requires a bit more work on their part. Else they wouldn't need Windows 10 to begin with.
