Trapdoor One Way Function 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 one way function in cryptography.

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. However if one has some additional secret information he can easily compute the. This module reviews the principles and requirements of asymmetric cryptography which uses a pair of keys with one party using a public. An example of a trapdoor one way function is factorization of a product of two large primes.

As in the case of ordinary one way functions it is easy to compute their values for given data but it is very difficult to compute their inverse functions. Video created by university of colorado system for the course asymmetric cryptography and key management. The problem of finding a one way function is thus reduced to proving that one such function exists. Trapdoor functions are widely used in cryptography.

Since this function was the first combinatorial complete one way function to be demonstrated it is known as the universal one way function. It is not known if a trapdoor one way function can be constructed from any one way function. 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.
