... However, since hash functions have a much larger input space than output space (e.g. SHA-256 output space has size 2 256, but its input space has size 2 18446744073709551616-1, which is substantially greater), chances are that the m' you get from leveraging the non-one-wayness will be distinct from the m you started with, and that yields a collision.

We present a binary tree based parallel algorithm for extending the domain of a universal one-way hash function (UOWHF). For For t 2, our algorithm extends the domain from the set of all n -bit strings to the set of all (( 2 t ?1 )(n ? m) + m) -bit strings, where

enter the zone barry sears pdf download In this paper, a novel algorithm for one-way hash function construction based on spatiotemporal chaos is investigated. A coupled architecture similar to that of a stream cipher named Rabbit is used in our scheme. The hash value is obtained through the XOR transform on the final state values of spatiotemporal chaos. Since the coupled architecture is a complex chaotic system, it is very

- A one-way function is a function which cannot be inverted. Simply put, the question boils down to why it is that one cannot get the original file that one checksummed from the checksum itself.
