"Random flood" crypto 
  Hi. I read this, it looks pretty old given the date though, but I was curious about the idea as it seemed kind of weird: [link] which suggests a type of "cryptography" that involves transmitting a huge "flood" of random data, such that only a tiny part is relevant to... more »

JSH: Generalizing quadratic residues solution idea 
  Earlier today I was pondering this weirdly simple idea for solving for quadratic residues I have and realized I should look at the generalization, so I wrote down: f_1 = ak mod p, and f_2 = bk mod p, and quickly realized I had: k = (a+b)^{-1}(f_1 + f_2) mod p with T = f_1*f_2 = abk^2 = abq mod p to solve for k, when k^2 = q mod p.... more »

Unique factor key and quadratic residues 
  Quadratic residues and factoring are intimately related using some basic congruences. And there is a uniqueness property with residues which appears to have been missed by practitioners in various math disciplines that consider factoring. This unique key is critical in determining quadratic residues by using... more »

noob question about AES & pigeonhole principle 
  Hi everyone ! This is a noob question. I've tried using AES recently (using SunJCE), & the result is surprising to me. If I try to encrypt a 3 bytes message using a 128 bits key, the cipherText is 128 bits (16 bytes), & when I decipher it the resulting message is 3 bytes. So apparently I can encrypt messages from 1 to 16 bytes, & the cipher... more »

JSH: But is quadratic residue idea new? 
  Finding a result is one thing but often I wonder afterwards, why is this result new? Now I'm in pondering mode as I consider something so trivially simple that it seems weird if it's NOT previously known. Because of the way congruences work, it's possible to do something interesting with quadratic residues, where I've simplified from the... more »
