Efficient Hybrid Post-Quantum File SecurityFramework

Moulay Ibrahim El‐Khalil Ghembaza

The shift towards a quantum-secured future has driven the demand for more practical ways of protecting filesthat can add post-quantum cryptographic components without creating a massive increase in computational or storagedemands. This study proposes and tests a hybrid file-security approach combining a post-quantum key encapsulationmechanism and authenticated symmetric encryption for real-world file security. An experimental research design wasfollowed with the use of a valid subset of GovDocs1 corpus as the evaluation sample, and the files were stratified basedon the format, size and entropy characteristics. Three different architectures were designed, built and evaluated fordesign evolution from direct lattice-style architecture to standards-based hybrid architecture. Correctness, runtime, andciphertext expansion were used to measure performance and compared to other files of various types and datacharacteristics. The results demonstrate the capability of the final framework to retain the exact reconstruction of thefile and gain significantly in storage efficiency and execution time over previous model generations. A comparison ofperformance over different heterogeneous categories of files showed no significant difference, and overhead was seento be a consistent decreasing function of file size. The results show that a hybrid design that can provide quantumresistant key protection and efficient authenticated encryption can be used to provide practical post-quantum-ready filesecurity. The study offers an empirically supported framework for the security of files in a post-quantum era and offersa repeatable foundation for research into implementing it for deployment.

AKQ: A Hybrid Quantum-Classical Image Encryption System

Tran Khanh Nguyen, Nguyen Thi Thanh Truc, Vu Tuan Hai

Image encryption is an essential field between computer vision and security which aims to protect the image before future attacks. Nowadays, it is threatened by quantum computers, which can break some classical cryptography. The encryption system has been upgraded from quantum key exchange protocol to post-quantum key-establishment mechanisms, but they are not explicitly designed for the image encryption task. In this paper, we propose a hybrid quantum-classical theoretical framework and its instance AKQ system which is more secure and suitable in the post-quantum era.

Post-Quantum Attribute-Based Encryption: a Comprehensive Survey of Lattice-Based and Hybrid Approaches

P. Purnima, Tejaswi Khanna, Deepak Kumar Verma

With quantum computing, traditional methods of encryption have become insufficient. This has led to the need for a transition to more reliable and flexible encryption systems. In this context, we examine the latest approaches to attribute-based encryption ABE schemes based on lattice cryptography and hybrid ones that combine symmetric encryption with public key ABE. These systems give post-quantum security in addition to fine-grained control, adaptive policy dynamic enforcement, and multi-level hierarchical control. We examine the most significant gaps regarding revocation, multi-authority frameworks, and ciphertext-controlled policies using LWE and Ring-LWE. Text length, key management complexity, and system interoperability are practical concerns too. A comparative analysis of five schemes shows each one's strengths and weaknesses. Designating the encryption phase speeds up the key generation process, so we implemented a multithreaded structure to address some of the identified performance constraints. This worked with other researchers designing robust quantum-access-controlled systems.
