A Composition Theorem for Universal One-Way Hash Functions
In this paper we present a new scheme for constructing universal one-way hash functions that hash arbitrarily long messages out of universal one-way hash functions that hash fixed...

Structural Properties of One-way Hash Functions
We study the following two kinds of one-way hash functions: universal oneway hash functions (UOHs) and collision intractable hash functions (CIHs). The main property of the former...

Duality between Two Cryptographic Primitives
This paper reveals a duality between constructions of two basic cryptographic primitives, pseudo-random string generators and one-way hash functions. Applying the duality, we pres...

Universal One-Way Hash Functions via Inaccessible Entropy
This paper revisits the construction of Universal One-Way Hash Functions (UOWHFs) from any one-way function due to Rompel (STOC 1990). We give a simpler construction of UOWHFs, whi...

haplog: A Hash-Only and Privacy-Preserved Secure Logging Mechanism
A secure logging mechanism named haplog is proposed. In essence, haplog uses only one-way hash functions to achieve the security and functional requirements of logging. This makes...
