The security is a research area in a continuous evolving field and represents one of the most important perspective future lines in telecommunications.This work is focused on new techniques and methods employing the properties of quantum physics with the aim of obtaining unconditional security.Currently, these techniques and methods lack a key rate close to the current transmission rate.In order to improve the quantum key transmission rate, this article proposes the use of cryptographic hash functions used in the privacy amplification layer to expand the bit rate relying on the properties of these functions.
