Very Large Cliques are Easy to Detect
It is known that, for every constant k 3, the presence of a k-clique (a complete subgraph on k vertices) in an n-vertex graph cannot be detected by a monotone boolean circuit usi...

Approximability of Minimum AND-Circuits
Given a set of monomials, the Minimum AND-Circuit problem asks for a circuit that computes these monomials using AND-gates of fan-in two and being of minimum size. We prove that t...

Graphs and Circuits: Some Further Remarks
We consider the power of single level circuits in the context of graph complexity. We first prove that the single level conjecture fails for fanin-2 circuits over the basis {, , 1...

Fault Jumping Attacks against Shrinking Generator
In this paper we outline two cryptoanalytic attacks against hardware implementation of the shrinking generator by Coppersmith et al., a classic design in low-cost, simple-design p...

Using Quantum Oblivious Transfer to Cheat Sensitive Quantum Bit Commitment
It is well known that unconditionally secure bit commitment is impossible even in the quantum world. In this paper a weak variant of quantum bit commitment, introduced independent...

Bounds on the Fourier Coefficients of the Weighted Sum Function
We estimate Fourier coefficients of a Boolean function which has recently been introduced in the study of read-once branching programs. Our bound implies that this function has an...
