On 6 Jan 2015 16:12 -0500, from kevinsisco61...@gmail.com (Kevin): > I figured I'd start building my own open source encryption algorithm: > https://github.com/kjsisco/qode To borrow a very apt quote from Bruce Schneier: "Who the hell are you?" [1] [2] Nobody is perfect. Even very clever people make mistakes when designing encryption algorithms. Sometimes they are unaware of particular attacks which turned the believed-secure algorithm into a trivially breakable entropy-reducing mess. Other times cryptographic advancements make previously infeasibly breakable algorithms feasibly breakable. Yet other times pure computing power did. Sometimes those same smart people come up which believed secure schemes that are trivially breakable by anyone with the right knowledge. [3] Which leads us back to the question: who are you? What are your credentials in the field of cryptography? Why should we trust _your_ algorithm over something designed by people with an established track record in the field? And also, _what problems_ do you see with current algorithms which you are attempting to solve, and _how_ do you intend to solve those problems? This is not meant to be sarcastic at all. Homegrown algorithms tend to fall very quickly to even a modicum of competent analysis. If you want the community to take your algorithm proposal (whatever it might be) seriously, then you need to show why the community should take it seriously. I once believed I had come up with a great encryption algorithm. Thankfully, it never saw any use beyond a few toy programs which I never distributed to anyone else.

If it's so foolish to build your own crypto, how foolish would a Fortune 500 company be to deploy it? Too bad there's not a crypto hacker service to test out various crypto algorithms.

The confidence in AES comes from its designation process during which many publicly tried and failed to convincingly reduce its security claim and the fact that it has (publicly still) stood the test of time : ten years later all we have are the bicliques which gains us 2 bits.

Re: [cryptography] QODE(quick offline data encryption)
Just use XXTEA. It's the only good cipher that allows for blocks of size equal to that of a disk sector. Additionally, maybe use XXTEA in CTR mode to provide additional confidentiality so that blocks with all zeroes won't output to the same value.

Take a look at for example RC4; it's been broken, but it's a _dead simple_ example of an encryption algorithm that for a long time stood the test of the community. (And it was designed by a well-known and well-renowned individual in the field of cryptography, who knows and knew the craft. Ever heard of RSA? One of those guys.) > $l = BinaryLen($b) > ;length in bytes > $br = BitRotate($b, $l) > ;left bit rotation So this is basically a Caesar cipher with the rotation amount equal to the plaintext length? If we assume for a second that the rotation is per-byte, that will be modulo eight anyway. I can try those eight combinations by hand if necessary; it'd probably be quicker than writing up a program to do it for me. Even if the rotation is bitwise over the entire plaintext input, the value is bounded by 8 * L, where L is the length in bytes of the plaintext input. For a full DVD (a little over 4 GiB), that value is about 32 billion, corresponding to right around 32 bits of key. Anything less than 128 bits of key is considered short, and 80 bits of key is considered breakable with some reasonable amount of effort by a determined attacker. Keep in mind that every single bit added to the key _doubles_ the attacker's effort, assuming a brute force mode of attack. > $x = BitXor($br, $l) > ;xor of rotation and length > $y = @YEAR > ;current year > $r = Random(20, 50) > ;random number > > $formula = $salt+$br+$x+$y+10+32+$r*100 > ;formula Wait, _what!?!_ Back up a few lines above, you assigned $salt to _include a representation of the plaintext input!_ > $t = $formula*$formula*$formula*Log($formula) > ;total So, for some transformation f(x) on the plaintext (your $formula assignment), _the output of which includes x_, we have that the algorithm is f(x)^3 * log(f(x)). I'm not really up to looking at the math of that right now, and the intricacies will depend on exactly what Log() in your language is, but I'm willing to bet that there is a trivial transformation of that right back to _x_, at which point we essentially have the original plaintext input. There should _certainly_ be a trivial transformation back to $formula, which is essentially the same thing. There isn't even a key in there that I can see, only a salt (which is included in clear in the output once you allow for the Log()). > $o = FileOpen("output.txt", 1) > ;create output file > FileWriteLine($o, $formula) > ;store the result Doesn't this mean that in your implementation, since $formula includes $salt which includes $b which is a representation of $i (the original plaintext input), the output file will contain a copy of that representation of the input? Presumably, StringToBinary() is trivially reversible. > FileFlush($o) > ;flush buffer to disk > FileClose($o) > ;close the stream The above took me all of a few minutes to look over and write up (mostly slowed down by your rather odd code formatting, causing me to have to look back and forth several times). And _I am definitely not an expert in the field_ and _have never used the language you wrote it in_. I'm just a mostly random guy who happens to do _programming_ for a living and have an _interest_ in cryptography. If we may assume that writing $formula to the output file is a simple bug, and you meant to write $t instead (a very embarassing bug indeed, but one that does not affect the _cryptography_), then is the entire security of your algorithm in what you call the "salt"? Is it even in the _length_ of what you call the "salt"? If so, you should start out with some basic terminology: _salts are meant to be public_ and are generally used so that _two plaintexts *hash* to different outputs_ in order to thwart dictionary or rainbow table attacks on hash values. They are, roughly, the _hash_ equivalent of an initialization vector. Here is an exercise for you. Assume that an adversary has access to the full and complete details of your algorithm. Also assume that the same adversary can run as many encryption attempts as they want to, on any plaintext input they choose to. Assume that they have access to the _particular_ implementation that the entity attempting to secure communications uses, as well as a copy of the ciphertext of the communication. Under these circumstances, _what_ property of your algorithm provides guarantees of _confidentiality_ against reasonable effort on the part of the attacker? -- Michael Kjörling • https://michael.kjorling.se • mich...@kjorling.se
