One-way functions and circuit complexity

R.B. Boppana, J.C. Lagarias
1987 Information and Computation  
In this paper we study a nonuniform notion of one-wayness based on circuit complexity.  ...  They show that a family of one-way one-to-one functions exists if and only if the nonuniform versions of the complexity classes P and UP are not equal, and that a family of one-way one-to-one and onto  ...

Pseudorandomness and the Minimum Circuit Size Problem

Rahul Santhanam, Michael Wagner
2020 Innovations in Theoretical Computer Science  
We explore the possibility of basing one-way functions on the average-case hardness of the fundamental Minimum Circuit Size Problem (MCSP[s]), which asks whether a Boolean function on n bits specified  ...  We show that under the Universality Conjecture, the following are equivalent: One-way functions exist; Natural proofs useful against sub-exponential size circuits do not exist; Learning polynomial-size  ...  Are one-way functions equivalent to auxiliary-input one-way functions? One-way functions are also relevant to proof complexity.  ...

Phasors from the linear algebra perspective applied to RLC circuits
English

Munoz-Quinones Gerardo, Garcia Hurtado Orlando
2016 International Journal of Physical Sciences  
Since the analysis of complex circuits with resistors, inductors and capacitors for sinusoidal entry types is time consuming, the sinusoidal analysis by phasors is a simple way to analyze such circuits  ...  Phasors provide a simple way to analyze sinusoidally excited linear circuits. Solutions of those circuits would be undoable otherwise.  ...  CONCLUSIONS In this article, we present another way, from linear algebra, that do not require the Euler identity, to show the relationship between the sinusoidal function, complex numbers and plane .  ...

The Pattern Basis Approach to Circuit Complexity [article]

Bruce K. Smith
2016 arXiv   pre-print
We describe and motivate a proposed new approach to lowerbounding the circuit complexity of boolean functions, based on a new formalization of "patterns" as elements of a special basis of the vector space  ...  We prove that a "pattern basis" with certain properties would lead to a useful complexity formula of a specific form, and speculate on how to find such a basis.  ...  Acknowledgements This paper wouldn't exist without the excellent expository blogs of Scott Aaronson and Timothy Gowers, which introduced me to the status of circuit complexity and to the "natural proofs  ...

Provably Secure Cryptographic Constructions [chapter]

Feebly secure one-way functions We want the size of circuits breaking our family of trapdoor functions to be larger than the size of circuits that perform encoding.  ...  This argument suffices for Hiltgen's feebly one-wayness result for the square matrix A −1 :fi rst we apply the first part of Proposition 6 and see that every output has complexity at least n 2 − 1, and  ...

On the complexity of slice functions

Ingo Wegener
1985 Theoretical Computer Science  
All the main methods known for proving lower bounds on the monotone complexity of Boolean functions fail to work in their present form for slice functions.  ...  By a result of Berkowitz (1982) , the monotone circuit complexity of slice functions cannot be much larger than the circuit (combinational) complexity of these functions for arbitrary complete bases.  ...  Acknowledgment I like to thank Les Valiant, Mike Paterson, Riidiger Reischuk, and Friedhelm Meyer auf der Heide for valuable discussions about this paper.  ...
