Title: Christoph Pacher: Innovator in Cryptography and Photonics

Introduction

Christoph Pacher is a notable inventor based in Vienna, Austria. He has made significant contributions to the fields of cryptography and photonics, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is a method for creating and distributing cryptographic keys. This method secures communication between two terminals by distributing signals for creating correlated values through a first communication channel that may be burdened with errors. The correlated values serve as keys, and a checksum is formed based on the first key present in the first terminal. This checksum is then transferred to the second terminal via a second communication channel. A second checksum is formed based on the second key, and information derived from both checksums is sent to a server. The server determines a correction value that aligns the keys, which is then applied to one or both keys.

Another significant patent is a device for generating polarization-entangled photons through parametric down-conversion. This device includes a waveguide structure made from an optically non-linear material with periodically poled regions. When operational, pump photons are supplied from a pump laser to the waveguide structure, and a separating means is arranged to follow the waveguide structure to separate the entangled photons for further conduction of signal and idler photons.
