For fixed public key is viewed as a function of that maps bits to bits.
Trapdoor one way function example.
A trapdoor function is a function that is easy to compute in one direction yet believed to be difficult to compute in the opposite direction finding its inverse without special information called the trapdoor.
On the other hand knowing one of the factors it is easy to compute the other ones.
Informally a function is a trapdoor one way function if.
In mathematical terms if f is a trapdoor function then there exists some secret information t such that given f x and t it is easy to.
A trapdoor function is a function that is easy to compute in one direction yet difficult to compute in the opposite direction finding its inverse without special information called the trapdoor trapdoor functions are widely used in cryptography.
A trapdoor function is a function that is easy to compute in one direction yet believed to be difficult to compute in the opposite direction finding its inverse without special information called the trapdoor trapdoor functions are widely used in cryptography.
To calculate xfrom f a trapdoor one way function has one more property that with certain knowledge it is easy to invert to calculate x from f x there is no proof that trapdoor one way functions.
A trapdoor one way function is a function that is easy to compute but computationally hard to reverse easy to calculate f x from hard to invert.
Then there is an efficient algorithm that on input produces such that for some trapdoor key.
In mathematical terms if f is a trapdoor function there exists some secret information y such that given f x and y it is easy.
Is a trapdoor one way hash function if is also a one way hash function i e if additionally.
The concept of function is defined and some example.
Such a function is hard to invert unless some secret information called the trapdoor is known.
A trapdoor one way function or trapdoor permutation is a special kind of one way function.
An example of such trapdoor one way functions may be finding the prime factors of large numbers.
It is a one way function and.
This video gives a motivation and a general idea about the concept of one way function in cryptography.
