One-way functions would separate P and NP
Earlier version 1. View current version 2 →
Statement
If standard one-way functions exist, then P ≠ NP.
Assumptions
- Standard polynomially bounded one-way functions; classical polynomial-time computation.
Scope
The reverse implication is not established; P ≠ NP alone is not a security guarantee.

P versus NP →
Conditional implication · Proved
This statement contributes context in its stated scope; it does not settle the canonical P versus NP question.
This is one indexed assertion in its own scope. No disjoint solved fraction, strongest-known ranking or additional parent resolution is inferred.
One-way implication
Average-case one-wayness is a stronger sufficient hardness premise.
P ≠ NP alone does not establish one-way functions or the security of a particular cryptosystem.
Details & sources
Standard one-way functions exist →
Open · version 1
There exists a polynomial-time-computable function that is hard to invert on average for probabilistic polynomial-time algorithms.
- The standard asymptotic cryptographic definition, efficient sampling and polynomially bounded encodings.
Scope: Average-case cryptographic hardness; stronger than merely worst-case NP hardness.
P ≠ NP →
Open · version 2
There exists a language in NP that is not decidable by any deterministic polynomial-time algorithm.
- Finite binary inputs; uniform classical computation; polynomial time in bit length.
Scope: The conjectural negative answer to the same canonical question.
