WebAug 16, 2011 · 1 Answer. Proving that breaking any cryptosystem is N P -complete would be a great achievement in cryptography, since P ≠ N P is probably the most "standard" … Web1 Answer Sorted by: 43 I don't think there is any compelling evidence that integer factorization can be done in polynomial time. It's true that polynomial factoring can be, but lots of things are much easier for polynomials than for integers, and I see no reason to believe these rings must always have the same computational complexity.

WebAs an example, consider the problem of factoring an integer into primes. Over the course of my life, I must've met at least two dozen people who "knew" that factoring is NP-complete, and therefore that Shor's algorithm -- since it lets us factor on a quantum computer -- also lets us solve NP-complete problems on a quantum computer. Often these ...

How does NP-Complete compare to NP-Hard? - Stack Overflow

WebMay 23, 2024 · 1. NP-complete problems are decision problems and belong to NP (and every problem in NP can be reduced in polynomial time to them, but these details I guess you already saw online). NP-hard are problems to which any problem in NP can be reduced, but not necessarily belong to NP or are decision problems. Obviously, every NP-complete … WebNP is finding the prime factors of very large numbers, in the realm of Google to Googleplex. Relations to Encryption: P is the "key" which allows us to decrypt the information when it reaches where it needs to go. NP encrypts the information with a long complex algorithm based on the concept of NP. algorithms. computer-science. WebApr 12, 2024 · NP-complete N P −complete problems are very special because any problem in the NP N P class can be transformed or reduced into NP-complete N P − complete problems in polynomial time. This means that if you can solve an NP-complete N P − complete problem, you can solve any other problem in NP N P. spar piershil

Is the integer-factorization problem (used for many

Webprove) is not NP-Complete. That means that no one has ever been able to convert Satisfiability (or any other NP-Complete problem) TO factoring. Factoring can be CONVERTED TO Satisfiability because it is in NP (you can see it there in the big oval at the top). Because factoring is not NP-Complete, a polynomail time solution to it WebNo NP-complete problems are known to be in P. If there is a polynomial-time algorithm for any NP-complete problem, then P = NP, because any problem in NP has a polynomial-time reduction to each NP-complete problem. (That's actually how "NP-complete" is defined.) And obviously, if every NP-complete problem lies outside of P, this means that P ...

WebA problem is in NP if and only if it has a polynomial verifier – that's the definition of NP. All NP-complete problems are in NP – that's part of the definition – and so have a polynomial verifier. Factoring is not a decision problem, so it neither belongs to NP nor doesn't belong to … WebWhen a problem's method for solution can be turned into an NP-Complete method for solution it is said to be "NP-Hard".

WebJan 10, 2011 · 2. This is simple actually. Multiplication is in P. NP is the same as "checking all possible polynomial sized solutions in parallel". If alpha is encoded as a length n bitstring, the factors total length is at most n + c. What it is not is "NP-complete". There is no way to turn an arbitrary NP problem into factoring. Share.

WebThe exact complexity of factoring integers (the decision problem) is a major open question in TCS (with important implications, especially in cryptography because of the RSA algorithm ), and is widely conjectured to lie "between" P and NP-complete (see the AKS algorithm and Shor's algorithm for two other key aspects of its significance).
