The answer is yes: the common definition of a "Lebesgue measurable function" from R to R is really a Lebesgue-to-Borel measurable function. There are examples of functions from R to R which are Lebesgue-to-Borel measurable, but which fail to pull back Lebesgue measurable sets to ...

More precisely, we apply a meet-in-the-middle preimage attack on the compression function and combine it with a guess and determine approach which allows us to obtain a 6-round pseudo preimage for a given compression function output with time complexity of 2496 and memory complexity of 2112. ...
Can you solve this real interview question? Preimage Size of Factorial Zeroes Function - Let f(x) be the number of zeroes at the end of x!. Recall that x! = 1 * 2 * 3 * ... * x and by convention, 0! = 1. * For example, f(3) = 0 because 3! = 6 has no ze

Preimage resistance is the property of ahashfunctionthat it is hard to invert, that is, given an element in the range of a hash function, it should be computationally infeasible to find an input that maps to that element. This property corresponds to one-wayness, which is typically used fo...

In this paper to investigate the avalanche criterion of this function, we will generalize the results of Coulter and Mathews regarding...
According to its designers, the function is designed to be an evolutionary lightweight alternative to the ISO standard Whirlpool. In this paper, we study the preimage resistance of the Maelstrom-0 hash function using its proposed 3CM chaining construction. More precisely, we apply a meet-in-the...
We study the security of AES in the open-key setting by showing an analysis on hash function modes instantiating AES including Davies-Meyer, Matyas-Meyer-Oseas, and Miyaguchi-Preneel modes. In particular, we propose preimage attacks on these construction
A method for determining a preimage element of a cryptographic hash function includes providing an output value of a cryptographic hash function and hash function operations of the cryptographic hash function; for each of the hash function operations, determining at least one hash function relation, ...
