Quantumctek CO from China, which specializes in quantum information technologies, has introduced a new approach to cybersecurity in the cloud environment. Their research is based on the use of quantum random numbers as encryption keys, which makes data protection from quantum computers more efficient.
This method is based on the shamir key distribution algorithm that allows you to separate private information between a limited group of persons. The information remains confidential until most of the group members combine their knowledge.
To increase the efficiency and reduce costs, the researchers added a staging of erasure inside the ciphertext before transmitting data by quantum key distribution (QKD). This not only provides quantum safety, but also increases resistance to possible failures.
Yun Zhao, Vice President Quantumctek CO, noted that their decision combines quantum safety and practical use of quantum technology and cryptography synthesis. "The keys generated by QKD guarantee safety both when you download the user's data to servers and during the transfer of data to distributed cloud storage nodes," he added.
Researchers have also taken tests to check if their approach can be used not only for transmission but also to store data. They have successfully undergone encryption/decrypting, storage of key information and storage of data, confirming its effectiveness.
This solution is viable both technologically and engineering, meets the standards of quantum cryptography and withstands the challenges that quantum calculations put before it. Given the ability of quantum computers to solve problems much faster than modern computers, the development of new generation cybersecurity becomes extremely urgent.
