MD4 is a hash function introduced by Rivest in 1990. It is still used in some contexts, and the most commonly used hash function (MD5, SHA-1, SHA-2) are based on the design princip...
In this paper, a technique to generate expander graphs using Cellular Automata (CA) has been presented. The special class of CA, known as the Two Predecessor Single Attractor Cellu...
Naor and Yung show that a one-bit-compressing universal one-way hash function (UOWHF) can be constructed based on a one-way permutation. This construction can be iterated to build...
Abstract. A simple one-way function along with its proposed application in symmetric cryptography is described. The function is computable with three elementary operations on permu...
In this paper we study the possibility of proving the existence of one-way functions based on average case hardness. It is well-known that if there exists a polynomial-time sample...
