Tests show that scaled-down versions of IBAA are unbiased for their entire cycle length. The alleged RC4 is used for comparison. No proofs of security are given.
What is the problem here? (Ignore ... The set of keys differing only in the input bits of the funnel can produce no more than half that number of hash values.
Functions that do not achieve avalanche make bad hashes and rotten ciphers. ... Change to ttlea() with NUMTEST=100 to whittle down the number of candidates ...
These changes are not backwards compatible: messages of all lengths will get different hash values from V1 ... Testing a trickle-feed mix was a new problem.
The problem is the per-character mixing: it only rotates bits, it doesn't really mix them. Every input bit affects only 1 bit of hash until the final %. If two input bits ...
Most input bytes are not treated commutatively. ... The only problem with this hash is that the result is a single byte, which is too small for many applications.
See http://burtleburtle.net/bob/hash/evahash.html Use for hash table lookup, ... If the length is included in the data being hashed, then lengths are not a problem.
... are a more subtle flaw. The last section shows that the new hashes have no funnels. ... is the first bit of each byte. What is the problem here? ... The proof can be found at http://burtleburtle.net/bob/hash/funnels.html. There is an efficient way of ...
