      Earlier today some folks published a paper that claims the SIMON cipher from the NSA has been broken, at least for the 32/64 variant. I've spent the last hour reading the paper, https://eprint.iacr.org/2019/474.pdf  , there's some really strange things in there ...

      There is no value of x that equals 2^x. Maybe it's a weird say that by 'size' they mean the size in bits, which has 2^size number of possibilities, but anyway, it's weird. That's just the first weird thing ...pic.twitter.com/LKsE40n4Px

      1 and 2 make a sort of sense. 3 is just ... wut. It's like defining a Function where keys can be mapped directly to cipher texts? The next section makes it seem like some kind of trial of all keys ...pic.twitter.com/9THIjP1rIr

      The next section is basically the Chewbacca defense. Focus on Yi. There is no other mention of Yi in this paper. Is it a typo? Was it meant to be Xi? If so ... Xi is uniformly distributed, it says so right above, not binomially.pic.twitter.com/JHYdE6QJzT

      Is this next bit basically saying that if the key size and the block size are the same, then some keys must produce identical cipher texts? Under what conditions? Obviously this is not true of a crappy block cipher that just uses the key directly as the cipher block!pic.twitter.com/omzm3BvcBJ

          O.k. so https://www.gutenberg.org/cache/epub/10/pg10.txt … is 4,452,069 bytes long, that's 556,509 64-bit blocks. Should there really be some kind of analysis of Birthday bounds?pic.twitter.com/5y4ClVDcU3

          There's a few other typos, it says 54-bits in one place, for example. My point with these weirdnesses isn't that they are flat-out wrong, it's that they are imprecise and missing links, and if you just broke an encryption algorithm, it's not helpful to convince the reader!

          Btw "Alba" is just the Scottish Gaelic word for "Scotland" ... so Alba3 means "Scotland 3". The authors claim to be in Edinburgh, but they use "ize" suffixes throughout, like "optimize".
