High power lasers and ethanol were trained to create scramble holograms to encrypt DataI, and to decrypt data with 90-95% accuracy.
A team of Greek scientists have developed an optical encryption system that could eliminate traditional hacking methods.
In a research paper published by Optica, researchers behind the system reveal that artificial intelligence (AI) and laser-generated holograms combine to provide a high level of data protection that can virtually be cracked. I’ve done it.
Unlike traditional encryption methods that rely on mathematical algorithms, this optical approach uses the physical properties of light to become resistant to attacks from the most advanced computers, including quantum machines.
How it works: Scramble light for security
“The demand for robust protection systems to combat digital fraud, from rapidly evolving digital currency to governance, healthcare, communications and social networks continues to grow,” says research team leader Stelios Tzortzakis. said Stelios Tzortzakis, research foundation. Technology Helas and the University of Crete.
To this end, the team’s optical encryption system relies on the chaotic pattern that is generated when a high-power laser interacts with a small container of ethanol for a scrambled light beam. This process is enhanced by thermal turbulence within the liquid, ensuring that the original information is hidden beyond recognition, making it nearly impossible to decode using traditional methods.
Researchers have turned to AI for ways to retrieve encrypted data. By training the neural network to recognize and decode the scramble hologram, we achieved an accuracy rate of 90-95% when acquiring the original image.
“We came up with the idea of training neural networks to recognize the very wonderful details of scrambled light patterns,” continued Tzortzakis.
“By creating billions of complex connections or synapses within a neural network, the original light beam shape was able to be reconstructed, which is a decryption key that is unique to the configuration of each encryption system. It meant there was a way to create the
“The methods we have developed are extremely reliable even in harsh and unpredictable conditions, addressing real-world challenges like difficult weather that limit the performance of free-space optical systems.”
Finally, he says, “The new system (of the team) achieves exceptional encryption by utilizing neural networks to generate decryption keys that can only be created by the owner of the encryption system. .”
The team tested the system by encoding and decoding thousands of images, including animals, tools, everyday objects, and handwritten numbers. but. The technology is not ready for commercialization as current laser systems used in the encryption process are bulky and expensive, thereby limiting its practicality and affordability.
