A Lightweight Secure Appliance for Database Encryption and Authentication Using Quantum Key

Cuiling Liu, Zhen Yao, Haoyu Hou +3 more

This paper presents a lightweight secure appliance for database encryption and authentication, leveraging quantum random number generator (QRNG) keys. The appliance functions as an integrated and transparent layer between application servers and relational databases, enabling fine-grained, field-level encryption and access control without requiring changes to existing systems. By integrating lightweight symmetric encryption, mutual authentication with digital signatures and ephemeral key exchange, and true quantum entropy for all key material, the solution achieves strong data confidentiality and integrity with minimal computational overhead. The modular architecture is suitable for edge, embedded, and enterprise environments, and supports seamless upgrades to post-quantum cryptographic algorithms, ensuring long-term data security in the quantum era.This paper presents a lightweight secure appliance for database encryption and authentication, leveraging quantum random number generator (QRNG) keys.

Research on Quantum Encryption Information Security Protection Technology for Distribution Networks

Jin Qian, Jun Luo, Chao Chen +1 more

To enhance the level of information security protection in the construction of the new power system of the energy internet, quantum encryption protection technology is introduced in the 5G wireless network multi-access edge computing (MEC) environment, enabling secure upgrades and transformations between distribution terminal devices and distribution main stations. This article introduces the current security status of 5G networks in the new power system and the problems encountered in the practical application of quantum technology. It elucidates the adaptation and transformation of the MEC environment and power terminal in the integration of quantum encryption technology, as well as the deployment plan in the main station. Finally, this article demonstrates the application in the distribution network scenario and provides a solution to meet the requirements of encryption upgrade in the power 5G wireless network.To enhance the level of information security protection in the construction of the new power system of the energy internet, quantum encryption protection technology is introduced in the 5G wireless network multi-access edge computing (MEC) environment, enabling secure upgrades and transformations between distribution terminal devices and distribution main stations.

Statistically secure uncloneable encryption of arbitrary messages

Archishna Bhattacharyya, Anne Broadbent, Eric Culf

Unconditional uncloneable encryption of a single bit with efficient encryption and decryption is now possible. However, whether the extension to messages of arbitrary length achieves statistical security remains to be known. Using the fact that the encoding bases for the single-bit scheme known to be secure consist of a subset of the Clifford unitaries, we show that this scheme can be upgraded to achieve unconditional uncloneable encryption for messages of arbitrary length, with encoding time polynomial in the message length and security parameter. This establishes that one-time uncloneable encryption of arbitrary messages enjoys statistical security.Unconditional uncloneable encryption of a single bit with efficient encryption and decryption is now possible.
