Properties of Neutrosophic κ- bi-ideals in near-subtraction semigroups [PDF]

Neutrosophic Sets and Systems
This paper presents the concept of neutrosophic κ-bi-ideals within the framework of nearsubtraction semigroups and explores the associated findings. The concept of neutrosophic intersections is explored.

Provable Second Preimage Resistance Revisited

, 2013
International audienceMost cryptographic hash functions are iterated constructions, in which a mode of operation specifies how a compression function or a fixed permutation is applied.

Preimage Attacks on 3-Pass HAVAL and Step-Reduced MD5 [PDF]

, 2008
This paper presents preimage attacks for the hash functions 3-pass HAVAL and step-reduced MD5. Introduced in 1992 and 1991 respectively, these functions underwent severe collision attacks, but no preimage attack.

Second Preimage Attacks on Dithered Hash Functions

, 2008
. We develop a new generic long-message second preimage attack, based on combining the techniques in the second preimage attacks of Dean [8] and Kelsey and Schneier [16] with the herding attack of Kelsey and Kohno [15]. We show that these generic attacks

Preimage of Tillich-Zemor Hash Function with New Generators

, 2013
We constructed a hash function by using the idea of cayley graph, hash function based on computing a suitable matrix product in groups of the form SL 2 (F 2 n ).We found collision between palindrome bitstrings of length 2n+2 for the new construction ...

On the Collision and Preimage Resistance of Certain Two-Call Hash Functions

, 2010
In this paper we present concrete collision and preimage attacks on a large class of compression function constructions making two calls to the underlying ideal primitives.

Solvability criterion for multiple interpolation problem in preimage of convolution operator

In this paper we find a solvability criterion for the multiple interpolation problem in the preimage of a convolution operator and, consequently, a criterion for the solvability of Abel - Goncharov problem in the same space.

Practical Preimage Attacks on 3-Round Keccak-256 and 4-Round Keccak[r=640, c=160]

IACR Transactions on Symmetric Cryptology
Recently, linear structures and algebraic attacks have been widely used in preimage attacks on round-reduced Keccak. Inherited by pioneers’ work, we make some improvements for 3-round Keccak-256 and 4-round Keccak[r=640, c=160].

A Second Preimage Attack on the XOR Hash Combiner

IET Information Security
The exclusive-or (XOR) hash combiner is a classical hash function combiner, which is well known as a good PRF and MAC combiner, and is used in practice in TLS versions 1.0 and 1.1.
