Bounds on the efficiency of black-box commitment schemes
Constructions of cryptographic primitives based on general assumptions (e.g., one-way functions) tend to be less efficient than constructions based on specific (e.g., number-theor...

New Combinatorial Complete One-Way Functions
In 2003, Leonid A. Levin presented the idea of a combinatorial complete one-way function and a sketch of the proof that Tiling represents such a function. In this paper, we presen...

Efficient Concurrent Zero-Knowledge in the Auxiliary String Model
We show that if any one-way function exists, then 3-round concurrent zero-knowledge arguments for all NP problems can be built in a model where a short auxiliary string with a pres...

Complete Classification of Bilinear Hard-Core Functions
Let f : {0, 1}n {0, 1}l be a one-way function. A function h : {0, 1}n {0, 1}m is called a hard-core function for f if, when given f(x) for a (secret) x drawn uniformly from {0, 1}n...

Efficiency Improvements in Constructing Pseudorandom Generators from One-Way Functions
We give a new construction of pseudorandom generators from any one-way function. The construction achieves better parameters and is simpler than that given in the seminal work of ...
