Quantum data protection algorithm

23.11.2023

QuantumCTek Co from China, specializing in quantum information technology, has introduced a new method for ensuring cybersecurity of data in cloud storage. Researchers have used random quantum numbers as encryption keys, increasing the level of data security from quantum computing.

The presented innovative cybersecurity solution based on quantum technologies provides a new level of data protection in the cloud. By using random quantum numbers as encryption keys and applying quantum key distribution (QKD), the system successfully demonstrates quantum security as well as efficiency and fault tolerance. This is an important advance in the field of cybersecurity, which can be extremely useful in the face of the growing threat of cyber attacks and the development of quantum computing.

The basis of the method is the Shamir key distribution algorithm, which allows you to share private information between a certain group of people. This information remains secret until the majority of the group members pool their knowledge.

To improve efficiency and reduce costs, the researchers implemented an additional erasure encoding step within the ciphertext before data transmission using quantum key distribution (QKD). This not only ensures quantum security, but also increases fault tolerance.

The new solution is a practical application of the synthesis of quantum technologies and cryptography, providing quantum key security, guaranteeing the security of user data when uploading it to servers and transmitting data across distributed cloud storage nodes.

The researchers also conducted tests to see if their method could be used not only to transmit data, but also to store it. Experiments including encryption/decryption, key information and data storage confirmed the effectiveness of the new approach.

The solution is technologically and engineering viable, complies with quantum cryptography standards, and provides effective protection against the challenges presented by quantum computing. Given the potential of quantum computers to solve problems orders of magnitude faster than modern computers, the development of a new generation of cybersecurity becomes more than urgent.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
