"Patent Filed for Satellite Cryptography"

The province of Lower Austria presented the best inventions and discoveries made by Lower Austrian researchers in celebration of the province's 100th anniversary. One of the presentations highlighted a patent filed for satellite cryptography. Univ.-Doz. Ernst Piller, who led the Institute of IT Security Research at the St. Pölten University of Applied Sciences for many years, developed the technology behind this innovation. Digitalization and globalization call for secure communications. Existing cryptography procedures encrypt data using a highly secure mathematical method. However, as computer performance improves, these methods become increasingly insecure, especially in the context of future high-performance quantum computers. Therefore, scientists have been working to develop physical methods of encryption. They began with quantum cryptography, which is expensive and thus cannot be used on a large scale globally, especially over longer distances. For the past 15 years, researchers have been developing a new method based on measuring radio channel properties that is both inexpensive and suitable for mass use, but it is only suitable for short distances of up to 20 kilometers. Researchers used satellites in a project to make the technology applicable over longer distances, hence the name satellite cryptography. According to Piller, there is not a single publication or patent for this method anywhere in the world, so the project has filed an international patent application to secure comprehensive protection for the research findings. This article continues to discuss the project on high-security, long-term cryptography for wireless communication using radio measuring data.
